Corey, the owner of Clyde Oak, was telling me about the process this kit goes through before it lands in your backyard.
Once you have the corners lined up, tighten them 75% of the way leaving some room for flexibility.
This was our way, I’m sure there are many many more ways to prep a raised bed for planting so please give tips or ask questions. To catch everyone up, Sunday night we went out on the sailboat and to put it lightly I punctured my leg while raising a sail. Containers also work great for urban gardens, that’s what we use on our roof (also great on patios). Ouch – that sounds like a pretty gnarly injury, hope your road to recovery is speedy!

Difficult to maintain (weeds, grass clippings, dirt get into stones, pain in the kiester, worse than weed-eating around the foundation).
I have always heard (no foundation expert here, just homeowner) that the dirt should go right up to the foundation and that, if you can see a crack between the dirt and the foundation, you need to water so the foundation will not crack. Now, on the north side of my house, the concrete driveway is directly up against the foundation, and there don't appear to be any cracks in either---so who knows? I'm considering French Drains for my back yard; big puddles form along the back fence (at least the yard is sloped correctly) when we get those week-long or drenching rains. The previous poster was right that a good visual indication that the soil under the foundation is getting too dry is when it begin pulling away from the footing. In regards to the rock around the foundation- not a smart idea especially if it's in the sun.
FWIW IRC Codes calls for the floor of the slab to be 8" above the exterior grade or grass. As others have already mentioned, you really need to have clear slab showing all the way around the house all the time. A concrete shed base is without a doubt the strongest and most durable form of shed foundation. A few days after I put together my raised garden beds, I headed to Menards to work on my soil.
I used weed mat that I purchased at Menards only to find out I still had some from our last flower project in our barn.
After mixing your soil mixture together and securing your weed barrier, dump your soil into the raised gardens. The danger of exhausting valuable aquifers by excessive pumping is paralleled by the threat of polluting the groundwater with industrial, agricultural and home landscape contaminants. If only one-half the amount of water required for healthy growth of your garden or landscape is applied at a given time, it only penetrates the top half of the root zone; the area below the point where the wetting front stops remains dry as if no irrigation has been applied at all.
Once enough water is applied to move the wetting front into the root zone, moisture is absorbed by plant roots and moves up through the stem to the leaves and fruits. The total water requirement is the amount of water lost from the plant plus the amount evaporated from the soil.
Category C-4 water is very high salinity and cannot be used for irrigation on a regular basis. Sodium is a major component of the salts in most saline waters but its impact can be detrimental to soil structure and plant growth beyond its status as a component of salinity.
Hard, firm baked, cracked usually too stiff or tough to work or ribbon* by squeezing between thumb or forefinger.
To determine if irrigation is needed, feel the soil in the soil zone where most roots are located. This type of watering allows moisture to penetrate into the soil area where roots can readily absorb it. Thoroughly moisten the soil at each watering, and then allow plants to extract most of the available water from the soil before watering again.
Mulching prevents compaction by reducing soil crusting during natural rainfall or irrigation. Most weed seeds require light to germinate so thick mulch layer shades them and reduces weed problems by 90 percent or more. Organic mulches decompose or sometimes wash away, so check the depth of mulches frequently and replace when necessary. Recent research indicates that mulching does more to help newly planted trees and shrubs become established than any other factor except regular watering. Four distinct methods of irrigating are sprinkling, flooding, furrow-irrigation and drip irrigation. Sprinkler equipment varies in cost from a few dollars for a small stationary unit to $50 or more for units that move themselves. Flood irrigation is useful where alkaline water causes a buildup of salts to toxic levels in the soil. Most gardens can be irrigated easily with the furrow method by using a hoe or shovel to make shallow ditches. Leaves and fruit of erect plants such as beans and peppers will stay dry during furrow irrigation. If trees and shrubs are surrounded closely by tenacious grasses such as bermuda, remove or kill the turf.
Trees need a deep, thorough soaking once a week in the growing season, either from natural rainfall or supplemental irrigation. Professionals indicate that large trees require more deep watering than homeowners can imagine. Young and mature pecans, which are popular lawn trees in many areas, respond positively to irrigation.
Growth of young, nonbearing pecan trees depends on a regular supply of water from April bud break to mid-August. Pecans require 1 inch of water each week from April to October; the optimum amount is 2 inches per week. Severe drought during one of these four periods can cause complete crop failure or serious loss. If waterings are too light or too frequent the lawn may become weak and shallow-rooted, which in turn makes it more susceptible to stress injury. Use the following steps to determine the amount of water your sprinkler or sprinkler system puts out and check its distribution pattern at the same time. Run the sprinkler or sprinkler system long enough to apply at least 1 inch of water or until runoff occurs. If runoff occurs, repeat above steps until at least 1 inch of water has been applied and allowed to soak into the soil. There are a number of wetting agents available; apply them according to directions on their labels. Generally speaking, if you keep your tomatoes happy, the rest of the vegetables will receive enough water. For fruiting crops, the most critical growth stage regarding water deficit is at flowering and fruit set.
In terms of food production, the period of yield formation or enlargement of the edible product (fruit, head, root, tuber, etc.) is critical for all vegetables and is the most critical for non-fruiting crops.
Irrigation, especially over irrigation during the ripening period may reduce fruit quality. One of the best techniques to use in applying water to home landscapes, gardens and orchards is drip irrigation. Use drip irrigation for watering vegetables, ornamental and fruit trees, shrubs, vines and container grown plants outdoors. Drip irrigation is not well suited for solid plantings of shallow-rooted plants such as grass and some ground covers. The basic concepts behind the successful use of drip irrigation are that soil moisture remains relatively constant, and air, as essential as water is the plant root system, is always available. With proper management, drip irrigation reduces water loss by up to 60 percent or more as compared to traditional watering methods. Drip irrigation requires little or no time for changing irrigation sets and only about half as much water as furrow or sprinkler irrigation because water is delivered drop by drop at the base of the plants. Water shortage and high energy costs motivate gardeners to harvest the greatest possible yield from every precious drop of water. The financial investment is reasonably small if you are willing to spend a few hours to plan, assemble and install the system. The life of a drip system is extended by proper design, proper filtering, avoiding puncture with tillage tools, mulching over plastic lateral driplines to shield them from sunlight, and flushing and draining lines and storing system components inside a warm building before hard freezing temperatures arrive. The 3- to 5-gallons-per-minute flow from a typical house faucet limits the area which can be adequately irrigated to usually not more than 1,500 to 2,000 square feet. From $15 to more than $30 per 100 feet of row can be spent for equipment in an average sized home garden, depending on whether it is simple or has fancy automatic controls, pressure regulators and fertilizer injectors. The two basic kinds of drip irrigation systems which have worked best for Texas growers are the two-channel plastic tubing represented by IRS Bi-Wall and Chapin Twin-Wall, and the plastic pipe with insert emitters represented by Submatic, Melnor Tirosh, Spot, Microjet and many others.
A source of clear water which flows at a rate of at least 2 to 5 gallons per minute with at least 30 to 40 pounds pressure is needed. The principal effect of salinity is to reduce the availability of water to the plant; however, certain salts or ions may produce specific toxic effects. Salts accumulate in the soil around the edges of the west area under drip irrigation emitters, and some leaching (removal of salts with drainage water) may be required. Other helpful facts involve the direction of downward slope in the garden and the gallons per minute delivered by your faucet. When buying irrigation equipment avoid mixing brands of fittings, hoses and emitters unless they are compatible. When a header is used, begin the installation by running a hose from the house faucet to a female hose connector which is installed in the end of the header closest to the faucet.
To join the Bi-Wall tubing to the header pipe (the main water supply), use a connecting attachment called an ear tee. All of the drip irrigation fittings are connected to the plastic tubing in the same manner. Trees previously irrigated by the other methods change their root systems when drip irrigation is used.
The following chart on emitter placement suggests a 1-gallon-per-hour emitter at the base of the plant, assuming you have a low shrub in sandy soil. When working with vegetable crops and sandy soil, use closer spacing (12 inches) to ensure that all shallow roots receive sufficient moisture. Water quality may be a factor in emitter location since salts concentrate at the edges of the wet area. A popular emitter arrangement for large trees such as pecans uses a loop which circles the tree between the trunk and the dripline. In-line emitter arrangements have been used satisfactorily for smaller trees such as apples, peaches and citrus.
Emitters are more easily observed, cleaned and oriented near the tree when they are located on the soil surface, although drip systems with underground emitters are out of the way. In landscaping, plants with different watering requirements must frequently be mixed together.
Once the system is set up this way, maximum benefit for all plants is achieved by several shallow waterings–leaving the water on for a short time (20 minutes to 2 hours) with an occasional deep watering (several hours) as needed, depending on season, plants and soil type. When watering closely spaced plants such as garden crops, flowers or shrubs using insert emitters, a system must have the capability to maintain uniformly moist soil near the surface along any row where you wish to germinate seeds. Knowing the total length of a drip hose required allows you to buy a ready-made kit with emitters already inserted in the hose.
Taking one step at a time in customizing a drip system to fit your planting area is fun and easy.
If the garden slope is only slight and there are only a few rows, put the header on the high end. For example, here is a hypothetical garden 20 feet wide and 30 feet long, with 25 feet from the hose faucet. Installing this emitter hose system requires only a knife to cut the hose and a twist punch or hand punch to install insert emitters.
Operating a drip system is a matter of deciding how often to turn it on and how long to leave it on.
Anyone can turn on a faucet for an hour or two every day, and some drip system manufacturers advise leaving systems on continuously for the entire growing season. Estimate daily operating time in hours by dividing the daily water requirement of each plant in gallons by the application rate to each plant in gallons per hour. The object of each watering is to bring the moisture level in the root zone up to a satisfactory level. Table 6 give the amount of water various plants need under a range of temperature conditions.
Divide the amount of water needed per week by the watering time to determine the number of waterings weekly.
Knowing the number of gallons delivered per hour by a drip system is also vitally important.
To calculate the delivery rate of a particular drip system, read the meter again, subtract the first reading from the second and divide the total gallons per hour by the approximate number of units of 100 square feet in the garden.
Another method of measuring the volume delivered by one emitter in 1 minute is to use a measuring cup or graduated cylinder. Probably the easiest method is to install an inexpensive water meter with automatic shutoff on the faucet.
For newly seeded gardens the system should be run only a short time every day for a few days to keep the surface soil from drying out. Most people new to drip irrigation notice immediately that the soil surface is dry except for a circle of moist soil right around the emitter.
The water which falls gently from the drip hose into the soil is pulled downward by gravity. It is easy to see why water from a drip hose in the row spreads out several feet in all directions even though only a small circle of wetness on the soil surface is visible.
Very often after spring or fall tillage, especially rototilling, the soil is fluffy and very loose.
For tilled soil to regain its ability to conduct the water sideways, soil particles must settle back together after each spading, plowing or rototilling.
The frequency and duration of drip irrigation also depend on the kinds of plants being grown. Three to 6 gallons of water daily usually is sufficient for a tree during the first and second year after planting. This responsibility is fulfilled by following the recommendations in this bulletin concerning water conservation and to further avoid practices that contribute to surface and groundwater contamination.

The two vigorous asparagus sprouts at right got me started building my second permanent raised bed in a year.
I guess I've saved what I think is the best reason for building a permanent raised bed for last in my list. The section shown at right from our main garden plot produced a succession of good crops last summer. Since our main plot in the Senior Garden suffered both from soil erosion and standing water at times, I also added a dry sump near the middle of the patch. Much of the content that ends up in one of our Senior Gardening feature stories started out as postings on our daily blog. Our asparagus bed is located on some gently sloping ground at the corner of our property that in the past has grown acceptable crops of tomatoes and broccoli.
With all the soil amendments added, including eight, forty pound bags of composted cow manure added last fall, the soil level of the plot was well above the surrounding area.
I already had some of the required treated timbers on hand, so I decided to go ahead and build a permanent raised bed for our asparagus.
Then I scraped away the topsoil with a garden spade to create a level surface for the first landscape timber. It's really, really important to make sure that first board or timber goes in level (both ways).
I generally don't get my trench level on the first try and end up rolling the timber in and out of the trench as I add or remove soil to level it. The photos below are from our main plot raised bed construction, but give a good look at rebar going in both at an angle (inset) and straight down. That's about all there was to it, although it took considerable time to get the rest of the raised bed done. I looked around the web just a little bit after completing this feature to see what else was out there about building raised beds.
Do note that Miles McEvoy, who works in organic certification with the Washington State Department of Agriculture, has said that no pressure-treated wood is allowed in soils used to grow organic food. After two winters, I noticed some minor heaving of the timbers in our large raised bed from winter freezing and thawing. Paul Calback shared his experience in building a raised bed for asparagus with me recently.
I added one more, possibly our last, raised garden bed in our main gardening area this week. It has taken a year, but I realized that I hadn't updated this page to reflect what probably will be a final raised garden bed on our property. The new bed is another with interior dimensions of 3' x 15' and sits beside a previous bed of the same size.
Differences this time around were that I had a nearly brand new 4x4 truck to haul materials, and I'd found a new source for good compost with which to fill the bed.
The soil in the new bed got to settle for a whole week before I transplanted what would turn out to be a fabulous crop of broccoli and cauliflower.
The area around the new raised bed is still low and subject to standing water after a heavy rain. As I write this update on April 2 (2015), we're getting some pretty heavy April showers outside. The ground around the raised bed when I seeded the peas was a muddy mess, but the raised bed was just about perfect for planting (other than the soil still being frozen here and there). With four raised garden beds now available to us, you might think we're done building raised beds.

Starting with the wood, it’s American timbered cedar that is preserved with an ancient Japanese technique called Shou-sugi-ban. Our amazing friends navigated us back to shore and stayed with me all the way through the hospital trip.
We may be too late this year to get started but I’m bookmarking the Clyde Oak kit for next year.
This rarely happens in a bed because presumably you're doing some watering to keep plants alive. It's called percolation when the sun hits something like rock and literally cooks the water out of the ground. You can have wet soil at a flower garden but if you're not watering evenly where grass meets the slab, that area will be dry and now you have uneven support of the foundation and it will eventually fail. We have tried to do a garden in the past and it often ends in a weedy rotting vegetable mess.
The reason why I choose Menards is I had several certificates that I had been collecting since apparently 2007. Leaves have thousands of microscopic openings, called stomates, through which water vapor is lost from the plant. It is the primary medium for chemical reactions and movement of substances through the various plant parts. Plants with insufficient water respond by closing the stomata, leaf rolling, changing leaf orientation and reducing leaf and stem growth and fruit yield. Prior to implementing an irrigation system, the water source should be tested for water quality.
Sometimes it is useful on soils with high gypsum levels and in low salinity situations where it can be chemically treated. It is imperative that a good moisture supply be maintained during seed germination and seedling emergence from the soil. A soil watered deeply retains moisture for several days, while one wet only an inch or so is dry within a day. Certain types of diseases live in the soil and spread when water splashes bits of infested soil onto a plant’s lower leaves. Grasses and weeds, especially bermuda grass, which grow around new plants rob them of moisture and nutrients.


A solid-set sprinkler system for a small garden could cost more than $100, although it is not necessary to spend that much.
Use sprinkler irrigation early in the day to allow time for the soil surface to dry before nightfall. It is often used in areas with extreme summer heat, especially in large farming operations. It can waste water because it is easy to apply much more water than is required to meet normal plant needs. Successful furrow irrigation requires soil with enough clay so that water flows along shallow ditches between the rows and sinks in slowly. New seedlings can be watered by running water as often as needed to keep the seedbed moist.
When summer rainfall is low and less than adequate watering occurs, competition for water and nutrients imposed by weeds or grass substantially reduced tree growth, bud development and fruit size. The longer turfgrass grows under trees and shrubs, the greater the reduction of new growth.
The safest grass killer for use near young trees and shrubs is glyphosate, which is sold as Roundup, Kleenup, Doomsday or Weed and Grass Killer. Use a piece of wood, cardboard, etc, as a shield to prevent spray droplets from touching trunks or foliage of desirable plants.
If the competition of grass for water can be overcome by extra watering, plants will grow much better. Remember that watering which is adequate for lawn grasses growing under trees is not adequate for actively growing trees. In general, pecans in good soil bear with only 32 inches of rainfall from August to October.
Therefore, consider a mid-winter irrigation to ensure good tree health and regular production. Consider this when establishing a lawn, for it may significantly reduce irrigation needs during the summer. After the sod is applied, soak it with enough water so that the soil under the sod is wet to a depth of 2 to 3 inches.
For soils high in clay, an inch of water is usually necessary to wet the soil to the desired depth. Vegetables which have most of their root systems in the top 18 inches of soil including beans, beets, carrots, cucumbers, muskmelons, peppers and summer squash. Moisture shortage at this stage may cause abscission of flowers or young fruits, resulting in insufficient fruit for maximum yield.
For example, the relative drought resistance of beans during flowering and early pod formation is the result of the lengthy flowering period — 30 to 35 days with most varieties. Moisture deficits at the enlargement stage normally result in a smaller edible portion because nutrient uptake and photosynthesis are impaired. Ample water during fruit ripening reduces the sugar content and adversely affects the flavor of such crops as tomatoes, sweet corn and melons.
In other watering methods there is an extreme fluctuation in soil water content, temperature and aeration of the soil. It is then left to dry out, and often it is not until the plant begins to show signs of stress that it is watered again.
If you have shied away from installing a drip irrigation system because it looked too complicated or too costly, this publication explains how to have one easily and economically.
Savings in water combined with increased yield and quality of vegetables and flowers more than pays for the cost of parts to maintain a drip system. Clean water is essential for successful drip irrigation because sand, silt, organic material and other foreign material can easily clog small emitter openings.
A filter system in the main line near the faucet is much easier to maintain than several filter systems scattered throughout the irrigation system. However, irrigation water adds salt to the soil, where it remains unless it is removed in drainage water or the harvested crop.
Poor quality irrigation water containing moderate amounts of salt often can be used more successfully with drip irrigation than with sprinkler or surface irrigation.
Sufficient rainfall is received in much of the state to accomplish any required leaching of salts. If the area is more than 100 feet from the faucet it may be difficult to get enough volume to run the drip system properly in a large area. Use graph or grid paper to draw the area’s shape using a scale of 1 inch to 5 to 10 feet. The distance from the water source to the edge of the area to be irrigated is the length of garden hose or plastic pipe needed to connect to the irrigation system.
Use a container of known volume, such as a 5-gallon pail, and a watch to estimate gallons per minute. The design and installation of Bi-Wall and Twin-Wall drip tubing and the design and installation of Submatic, Melnor, Spot and Microjet emitter systems are discussed separately so that the instructions are easier to understand.
At each row, punch a small hole in the side of the 16-millimeter header tubing facing down the row. For the hose connector, push the 16-millimeter header over the shaft and under the locking collar.
When designing a drip system with insert emitters, strive to have the same amount of water flowing out of all emitters in the system. With finer soils, use greater distances between emitters while still ensuring proper coverage.
It may be necessary to locate emitters so that wet areas overlap the tree trunk to prevent harmful salt accumulations near the trunk. Install two or four emitters in the lateral so that wet areas overlap in line with the tree row.
Some emitters perform satisfactorily underground while others must be used only above ground. Some emitters can be flushed easily to remove sand or other particles which cause clogging, while others are more difficult to clean. When native plants are transplanted they often require watering for the first year or so until they establish a root system. Some ornamentals require occasional deep watering, while others prefer more frequent shallow watering. A tree with only 25 percent of its roots wet regularly will do as well as a tree with 100 percent wetting at 14-day intervals. If emitters are placed on only one side of a tree, the root system is not balanced and stability is threatened. You do not use the same spacing for all vegetables and flowers and you must not grow the same kind of plant in the same spot year after year.
Roots soon penetrate the soil around the plant in a radius several feet from the stem, and absorb water from every cubic inch of this soil.
Lay enough garden hose to reach from the house faucet to the area to be irrigated, attach the hose end to the coupling on the emitter hose and unroll the hose down the first row. First, select an emitter that delivers 1 to 2 gallons per hour when operated in a pressure range of 2 to 10 pounds per square inch. That is why water flows faster from the emitter nearest the header and slowest from the emitter farthest from the header. For steep slopes where rows must be contoured, run the header down the slope and the emitter hose across the slope with the contour.
The object is to maintain adequate soil moisture without wasting water by applying too much. Continuous irrigation may be required for short periods when water use by the plants is maximum, but continuous operation when it is not required offsets the basic advantage of minimum water application with drip irrigation. Any more means cutting off necessary oxygen along with the loss of water and nutrients below the root zone. For example, a closely spaced vegetable garden in medium soil needs to be watered for 2 hours at each watering, and with warm weather the garden needs 6 hours of water each week. This makes it difficult to give each type of planting optimum watering, but with some care results can be more than satisfactory.
If the delivery rate of a system is known, one can easily decide how long to leave it on to get the desired amount of water. Divide the gallons per hour per 100 square feet by 60 to see what fraction of an inch is applied in 1 hour.
At other times it is a waste of water because tremendous quantities evaporate from a wet soil surface. It is also pulled sideways, moving from one tiny soil particle to the next by a force known as capillary attraction.
Actually, the dry surface soil prevents moisture from evaporating into the air, thus conserving water. Sprinkle irrigate an inch of water on the entire garden after spring and fall tillage to settle soil particles so that the soil will conduct water laterally as well as downward.
In June and July rainfall is less, and higher air temperatures and longer days cause plants and soil to lose much more water into the air.
When temperatures reach the high 90’s and humidity is low, fruiting tomato plants require irrigation every other day with at least an inch of water for maximum production. If the zone of moistened soil is increasing in size, reduce operating time; if the moistened soil zone is decreasing in size, increase operating time.
For instance, tomatoes use more water than any other vegetable in the garden when full grown and laden with fruit. Only 3 to 6 hours of irrigation time are required daily during maximum water use months if one 1-gallon-per-hour emitter is used at each tree.
Each gardener utilizes a small part of the total water consumed, but the total use by all gardeners is significant. Among the threats to pure water are improper use of fertilizers, pesticides and soil erosion. Water flows through the large tube and into the small tube through holes spaced every 4 to 6 feet. The ears are two semi-rigid loops of plastic that are looped over the header pipe to prevent the tee from being pushed out by water pressure. This emitter is plugged into flexible plastic pipe permitting water to flow out of the pipe at a very slow rate at any point along its length.

I've used raised beds in the garden for a long time for growing intensive plantings of onions, carrots, beets, and such. Some folks just like the appearance and order of a garden or flower bed neatly contained with landscape timbers. Our first raised bed (shown below), more of a terrace until completed this spring, was built for that purpose.
This drying can allow the gardener to get back into the garden more quickly after heavy rains. The spring intensive planting of onions, carrots, beets, and more onions was easily accessible from the side and via walking boards on the interior. A dry sump is simply a homemade drain where you dig as deep as you can with a post hole digger and fill the hole with coarse builders' sand.
I deep dug the plot in 2006, mixing copious amounts of composted cow manure, peat moss, bone meal, and lime into the soil before transplanting asparagus plants I'd grown from seed into it.
I'd used a couple of old boards to hold most of the soil in place, but it was obvious this spring that something better was needed. My first step in building the bed was to extend the true north-south line I'd built our main raised bed on.
I dug and leveled the trench for the timbers and placed the base and one top timber to be sure it was all going to work out right. I angled two of the pieces against the expected force of the soil inside the new bed with the other piece angled the opposite way just for good measure.
On our first raised bed, I anchored the base pieces first and ended up using a lot more of the rebar than may have been necessary. I found that I exhausted the battery pack on the drill after about 4 holes through the doubled timbers. When I did, I used the circular saw to cut on each side of the 6" timbers and finished the cut with my chain saw. Not everyone will want to invest as much as I have in my raised beds, and some may want circular or irregular raised beds for landscaping purposes.
The old CCA (chromated copper arsenate) treated lumber or timbers have the danger of leaching arsenic, a carcinogen, into your soil.
All ACQ types contain 2 active ingredients which may vary within the following limits: copper oxide (62%-71%), which is the primary fungicide and insecticide, and a quaternary ammonium compound (29%-38%), which provides additional fungicide and insect resistance properties.
Are Pressure Treated Woods Safe in Garden Beds by Phil Wood (no relation) gives some alternatives to ACQ treated timber if you're still a bit wary about using it. After manhandling the heavy treated timbers and then hammering in twenty-seven pieces of rebar in two days, my hands were swollen and my whole body ached for days afterward!
It's quite similar to our asparagus bed in construction, although I did change the dimensions a bit.
Subtracting the width of the timbers, it leaves about 36" of usable gardening space inside.
As you can see in the photo above, I haven't finished backfilling around the outside as yet. That may be because I anchored the base first and then drove more rebar through the top and anchor timbers. I had lots of peat moss and screened compost available, so they were mixed with the existing soil to make what I hope will be an ideal growing medium.
There's actually room for a wide aisle and one more narrow raised bed, probably similar in size to the one I just put in.
I got started leveling ground and laying the base timbers on March 31, 2014, finishing the project the next day. The area for the bed is on part of what was the original garden plot when we moved to our Senior Garden. Defying proper crop rotation, we seeded the bed to kale after the broccoli and cauliflower came out. Fortunately, I'd tilled the bed in the fall and covered it with grass clipping mulch for the winter. But I keep looking at the area around our shallow well cover, thinking an herb garden in a raised bed might go really well there.
Even with our wonderful, current raised beds, I was a little envious of his raised bed construction. Clicking through one of our ads will produce a small commission for Senior Gardening for any purchase you make, and you won't pay any more than you would have by directly going to the vendor's site. Plant health, moisture retention and proper drainage are all achieved with raised beds and also when you choose the right ingredients to fill your raised-bed garden. You can purchase it in bags from a garden center or in larger, bulk quantities from soil and gravel dealers.
Use a blend of composted manure, composted wood products and humus from composted leaves and vegetation. Meaning you live in the city, don’t have enough yard space, or just feel totally overwhelmed by the thought of 600sqft. You can search for more videos on this online to see the full process, but basically the wood is charred with a flame to naturally create a rot and insect resistant slab of wood. Nie hatte eine Idee, uber diese, wird fur mehr solcher informativen Beitrage von Ihrer Seite aussehen. It is designed by our brand building studio Wild Measure based in Raleigh, North Carolina & Traverse City, Michigan. The bottom of the shallow trench should slope, with the high point being in the middle of the wall. Would the stones in the flower beds be considered an impervious area even if the water ran off to the grass outside of the flower beds along the perimeter of the foundation? Otherwise, I think using a soil that is designated for vegetable growing will probably work just as well!
This continual loss of water called transpiration, causes the plant to wilt unless a constant supply of soil water is provided by absorption through the roots.
Evapotranspiration rates vary and are influenced by day length, temperature, cloud cover, wind, relative humidity, mulching, and the type, size and number of plants growing in a given area. Water is an essential component in photosynthesis and plant metabolism, including cell division and enlargement.
The instructions for testing and the testing results may be obtained from the Texas AgriLife Extension Service or an independent water lab. On well drained, low salt soils, the water can be used for salt tolerant plants if it is well managed. As you gain experience feeling the soil and observing plant symptoms, it will help you time irrigations.
Fresh grass clippings are fine for use around well-established plants, but cure them for a week or so before placing them around young seedlings. They are inexpensive to buy, but if used incorrectly they can be extremely wasteful of water.
The best investment is an impact-driving sprinkler than can be set to water either a full or partial circle. Salt does not accumulate because water percolates downward from the surface carrying salts with it. Beneficial flooding is possible only if the area is level and the soil contains enough clay to cause the water to spread out over the surface and penetrate slowly and evenly. The surface soil of a raised bed does not pack as with sprinkler irrigation, so there is less crusting. When competition from grass is eliminated, roots are more evenly distributed, root numbers increase and they utilize a larger volume of soil.
To water large trees let water flow slowly onto an area under the dripline of the tree for several hours. After a couple of weeks root system development should be well under way and the watering frequency can be slowly reduced.
Grass under drought stress also shows evidence of tracks after someone walks across the lawn. The worst time to water is late evening because the lawn stays wet all night, making it more susceptible to disease.
Early in the season when plants are young and have small root systems, they remove water from the soil near the center of the row.
These vegetables withdraw water from the top foot of soil as they approach maturity and can profit from 1 to 2 inches of water per irrigation. Slight deficits during part of this period can be partially compensated for by subsequent fruit set when the water supply is adequate.
Moisture deficits at ripening do not significantly reduce yield of most fruit crops, irrigate at this time with extreme caution.
The water flows under low pressure through plastic pipe or hose laid along each row of plants. When the soil is saturated in this way, there is little or no available oxygen; at the end of the cycle there is insufficient water. Water applied in excess of this penetration rate can only run off the surface, removing valuable topsoil and nutrients. Most city water sources do not require a filter; however, some gardeners add a filter to avoid clogging. Y-type, in-line strainers containing single, 100-mesh, corrosion-resistant screens (such as stainless steel or bronze) are usually adequate for filtering small amounts of sand, rust particles, etc.
All water from streams and underground sources contains dissolved materials known chemically as salts. When the amount of salt added to the soil exceeds the amount removed, salt accumulates until the concentration in the soil may become harmful to plants. However, extra irrigation water may be required in some areas to leach accumulated salts from the root zone.
A large fruit or ornamental tree having a canopy spread of 15 feet or more in diameter needs six emitters. Count the number of rows and multiply the number of major rows by the row length to get the total length of drip hoses needed. Divide irrigation systems for larger areas into two or more sets when the water volume is insufficient to cover the whole area at once. Secondly, have the flow rate regulated so that water drips into the soil without puddles forming on the surface. It is best to start drip irrigation at the beginning of spring growth to allow time for new roots to develop before hot weather arrives. In sandy soil where spaces between sand grains are relatively large, gravitational forces affect water movement more than capillary action.
Increasing the wet area encourages wider development of the root system, and watering time is reduced somewhat.
To get a better idea of soil structure experiment with slow water applications to observe lateral movement and depth of water penetration. In-line connections are made by cutting the pipe and connecting the emitter to the pipeline at the cut. Differing needs can be satisfied through the number or size of emitters by placing either a greater number of emitters or by using emitters with a greater flow rate for plantings requiring extra water. This not only hides the tubing from view but also adds to the system’s life expectancy.


In one experiment with drip irrigation, a large crop of trees was blown over in a storm because the roots had been watered on one side only.
All things considered, a spacing of 2 feet between emitters is best for most closely spaced plants and soils; a spacing of 18 inches might be better in very sandy soil. At the end of the row, curve the hose back up along the second row and so on for remaining rows.
One emitter commonly used in Texas is rated at 2 gallons per hour when operated at a pressure of 10 pounds per square inch. Water is wasted at the beginning of the row to get enough water into the soil at the end of the row.
Divide this number by 60 to get the gallons per minute your water source must supply to allow the system to irrigate uniformly. Knowing how often and how long to water depends on the system’s rate of delivery, soil type, varying weather conditions, kinds of plants, their growth stage and cultural practices in use. Plants with shallow root zones and shorter watering times benefit from more frequent applications. To apply a 1-inch irrigation to a garden, run the system long enough to deliver about 60 gallons for each 100 square feet of garden area. The small circle of moist surface soil around a drip irrigation emitter is like the tip of an iceberg, because after a few hours of irrigating a great volume of water under the emitter has spread out through the soil for several feet in all directions. The slower the water flows into the soil, the greater is its sideways flow relative to its downward flow. Instead of spreading out and wetting the entire soil volume in the garden, the water travels almost straight down.
Generally, water spreads sideways more in clay loam than in sandy loam soils, but there are exceptions. Watch the weather and record the amount and frequency of rainfall, remembering that supplemental irrigation may be necessary even in a rainy week if the required amount has not been supplied naturally. In the fall, with the return of more frequent rainfall and cooler temperatures, allow more time between irrigations.
Label instructions on all pesticides and fertilizers must be followed faithfully and water run-off due to excess irrigation should be minimized. But I had never put in any permanent raised beds, always just building a plateau of raised soil for the plantings.
I really don't recommend building a raised bed this large, but this one fits our current needs. It is especially valuable in the spring when frequent rains make getting cool weather crops into the soil difficult.
But even with that dimension, I can reach in from the ends or the sides and work any part of the raised bed without stepping into it. We followed the spring planting with a crop of lettuce that lasted until Thanksgiving with the aid of a portable cold frame.
It isn't fancy, and it certainly isn't a perfect drain, but it helps dry things out in the middle of the plot. I was fortunate that I wanted the end of the new bed to be along the same line as our main raised bed. Mine wasn't terribly expensive, as I picked it up several years ago off the sale table at a local hardware store. To get the side straight, it was necessary to use stakes and twine to keep my sides straight. Since I had to use my circular saw to start my cuts on the timbers, I needed power at the site anyway. I would have never thought of that on my own, but years and years ago, I worked as a carpenter's assistant for one summer. If I were building a raised bed just for vegetables or flowers, I'd make the inside width an even three feet to make everything easy to reach.
Overlapping the corners also made the side pieces overlap, adding strength to the sides and making it much easier to keep the sides straight. I ran outside as I was finishing up this feature and snapped a shot of the Senior Garden, showing the asparagus bed in the foreground, the main Senior Garden, and our original garden plot at the back. Shipping lumber can get a bit expensive, though, so you might want to take a peek at the ads and then design your own raised bed from what you see in the ads. It would be better to recruit a strong helper for such a job than doing it by oneself (as I did). Since this feature is already way too long, I shared his email and photos on my garden blog. It's approximately 16' long (15' interior), consistent with our other two raised beds in the area. But even on the one end I did backfill, I needed a couple of lumber scraps to drive the rototiller into the new bed.
All the years of gardening have caused the soil there to settle considerably, despite all the soil amendments we had added to the area. We got lucky on that one and got a good crop, although I'd prefer not to tempt fate in the future by growing two brassica crops in a row in the same area.
In mid-March, I pulled back the mulch and seeded the bed to tall, early peas, which were just beginning to break the soil surface yesterday.
Of course, he did his beds on a much larger scale than we did ours and with a far, far greater budget. Add the soil ingredients in layers and mix and water at regular intervals as you fill the beds. Quality garden soil supplies basic nutrients and a coarse particle size to help with drainage. Buy it in compressed bales then cut them open and break up any compressed clods that may have formed before adding them to the raised bed. If you are in a city and placing it on cement there is no need for creating this barrier if you do not want to. I recently sold a house that had a 20' stretch of side yard without any beds and I used a soaker hose to keep it moist since I didn't water the yard in that house.
You can use layered cardboard with newspapers for your weed barrier if you prefer to go a more frugal route.
Water moves downward through a sandy coarse soil much faster then through a fine-textured soil such as clay or silt. The results of the test will determine if the water is suitable for irrigation or reveal if any special tactics will be required to overcome quality deficiencies. These symptoms should be the same, since they result from insufficient water in the plant tissue. Mulching also keeps fruit clean while reducing rot disease by preventing soil-fruit contact. Different amounts of water can be applied to separate plantings to match plant requirements. If you have poor quality water, the mist which dries on leaves may deposit enough salt to injure them.
Also, rapidly growing plants are injured by the low oxygen level present (oxygen starvation) in flooded soil, and fruits resting on flooded soil stay wet, often rotting as a result. Many sandy or open soils are so porous that water seeps in too quickly, never reaching the end of the row.
If the water sinks in too fast at the high end, divide the garden lengthwise into two or more runs and irrigate each run separately.
Only a hoe or shovel and a length of hose are needed to get the water from the house faucet to the garden. Effective soil utilization by a large root system means that fertilizer and moisture will be used more efficiently.
For instance, if the growth of a tree is reduced by 20 percent for one year because of grass competition, the growth automatically is 20 percent less during the second year’s growth. At about 1 month after seedling or sprigging the lawn it should be treated as an established lawn. Roots develop fairly rapidly and within 2 weeks or so the sod can be treated like an established lawn. Use this information to find out how long it takes your sprinkler to apply 1 inch of water. As the plants grow larger, roots penetrate into more soil volume and withdraw greater quantities of water faster. More determinate crops such as corn or processing tomatoes are highly sensitive to drought during the flowering period.
The water drops out into the soil from tiny holes called orifices which are either precisely formed in the hose wall or in fittings called emitters that are plugged into the hose wall at a proper spacing.
Drip irrigation overcomes this traditional watering problem by keeping water and oxygen levels within absorption limits of the plants. Filters with replaceable cartridges, synthetic-fiber fabric elements or multi-stage screens such as 100- and 180-mesh are required where water contains larger amounts of sand. In addition, a uniformly high soil moisture level is maintained with drip irrigation, which keeps the salt concentration in the soil at a lower level. Operating the system when the crop’s water requirement is low can probably accomplish required leaching of salts in most cases. If you run several rows close together (only a few inches apart) to create a bed culture, consider using one drip hose if it is up to 18 inches wide and two drip hoses if it is 24 to 36 inches wide.
Insert emitter systems are ideally suited for irrigating trees, which are planted farther apart than garden crops, flowers or shrubs. If drip irrigation is initiated in midsummer, an occasional supplemental irrigation by the old method is recommended to avoid plant stress. However, remember that smaller volume emitters clog more easily than larger volume emitters.
Observe the application rate and time so better decisions on emitter placement, as well as watering practices, can be made.
Emitter openings must be small to release small amounts of water, consequently, they clog easily. In clay soils it is best to increase the number of emitters rather than the rate of flow since soil density limits absorption rates. If the kit has a Y hose for equal lengths of hose connected to each leg of the Y, put the Y near the center row at the high end. Well-designed small systems can be operated with no more than 10 to 15 percent variation in flow rate. If the garden is level, it is easy to shorten the length of run by placing the header in the center (halfway down the length of the garden).
For example, 100 emitters multiplied by 2 gallons per hour per emitter equals 200 gallons per hour, 200 gallons per hour divided by 60 equals 3.3 gallons per minute. Measure pieces of header hose and push them into the compression fittings (tees) so that the drip hose lines up exactly with a center of the row. If plants are showing signs of insufficient moisture and watering duration is long enough (see Table 5), then shorten intervals between watering. Other plants requiring deeper watering are satisfied by emitters with greater outputs, or in the case of clay soils, a greater number of emitters.
Likewise, a system with a 30-gallon-per hour rate of delivery would do the same job in 2 hours. Some homeowners have added so much organic matter to their sandy soil that the water from an emitter travels outward in a circular pattern, wetting soil 3 feet away from the emitter to within 3 inches of the soil surface. Non-essential use of water implies a special responsibility on the part of gardeners to efficiently use the resource and to protect its quality. This system allows water to be distributed evenly along a relatively long row of up to several hundred feet.
Then the water drips out of tiny holes formed every 12 to 18 inches in the walls of the outer tubing. The photo at right is of our big raised bed and our non-raised, older garden patch after a heavy, spring rain. Of course, that part of the garden plot had served for several years as our composting area, as the slope and subsequent erosion discouraged other efforts there. I used stakes and twine to extend the north-south line to and past the site for the new raised bed. Lacking surveyors tools (or skills) to accurately survey the slope involved, I later realized a second layer of timbers would be required on the high side, as the base would disappear into the soil.
As it turned out, 42" was just barely enough, as my original planting of asparagus roots had spread beyond the original 3' wide bed, and I ended up cutting roots as I dug out to lay the timbers on each side! If I were to redo this project, I'd probably sink a short stub of timber under any junction of single deep timbers to prevent heaving. I went with a slightly narrower raised bed this time, as I've found it a bit difficult getting to the center of our asparagus bed from the side during the summer. Building the bed allows us to continue gardening an area that often is too wet for any gardening activity. And of course, you can work such a bed from the side, even standing in mud, without damaging the soil structure of the raised bed. But there are lots of nuggets of knowledge on building raised beds in his podcast and in his show notes at the bottom of the page that may prove helpful to my readers. Peat moss is especially important in a raised bed because the soil dries out more quickly above ground than it does underground especially if you live in an area with hot, dry summers. So nothing is leached off into the soil, in fact it fortifies the soil and creates a stronger crop. I find a Miller High Life does the trick but I would recommend checking in with your grandpa or grumpy old neighbor if you need assistance in beer selection.
You can instead place it on top of a flat large piece of wood so it is easy to move and clean up after if you choose to move it. If needed, put your gravel or river rock or whatever inside the trench, but never above the footing. Light sprinkling only settles the dust and does little to alleviate drought stress of plants growing in hot, dry soil. Make a serpentine ditch to guide the water up and down short rows in small gardens on level ground. With careful observation and experience, one can determine the correct number of days between waterings. It frequently (even daily) replaces the water lost through evaporation and transpiration (evapotranspiration). Filters should be equipped with cleanout or flush valves to easily remove trapped particles. Garden rows should be level or only slightly downhill (not more than 1 to 2 percent grade) even if it is necessary to run them on the contour (around the hill instead of up and down it).
The number of emitters multiplied by the rated output per emitter gives the flow rate needed to irrigate all the trees and shrubs simultaneously.
In finer soils such as clay, capillary action is much stronger and water spreads laterally before penetrating very deeply. Additional lengths of pipe 8 to 12 feet long, each containing another emitter, are connected to the initial loop as the trees grow and require more water. Rodent damage (sometimes they chew through the tubing) and accidental damage from shovels or tillers are problems associated with buried systems. In actual practice the emitter would be operating at a pressure somewhere between these two extremes.
If your water supply is 5 gallons per minute, design the header hose to irrigate the garden in one set; if your water supply is only 2 to 3 gallons per minute, divide the header into two sets using a tee with two shutoffs to permit irrigating each half of the garden separately. Row shutoffs and flow control valves can be omitted, but the system would be less versatile and less uniform in flow rate. Then, punch a hole with the twist punch along the top side of the drip hose every 2 feet and press an emitter into each hole.
Water requirements are influenced by tree size and growth as well as rainfall, temperature, relative humidity and wind velocity. Again, divide your gallons per hour by the number of units of 100 square feet in the garden to get gallons per hour per 100 square feet. The lush growth of asparagus hinders access, but a shorter reach in the new bed will be helpful. Soils in wet climates with lots of rain lose nutrients even faster than soils in drier climates.
If your soil is overly sandy and falls apart in your hand when you form a ball with wet soil, it is overly sandy and needs less vermiculite than more dense soil.
Of course, you'll need to make sure the water has a clear path away from the house when it reaches the end of the trench.
Some water also is wasted by attempting to cover a square or rectangular area with a circular pattern. The number of rows which can be irrigated at the same time depends on the volume of water available and your ingenuity. In areas with salty water, salts accumulate near the center of the row and can injure plants.
Common bermuda grass lawns can go 5 to 7 days or longer between waterings without loss of quality. In addition to maintaining ideal water levels in the soil, this also prevents extreme temperature fluctuations which result from wet-dry cycles associated with other watering methods. Daily flushing is necessary where water contains moderate amounts of sand or other material. Place small irrigation pipes (drip hoses) right along the row; water drips out more uniformly when the rows are level or slightly downhill. For example, if there are 12 trees on which 72 emitters will be used, each with a rated output of 1 gallon per hour at 15 pounds per square inch, the flow rate will be 72 gallons per hour or 1.2 gallons per minute. If the water contains sand or dirt particles, screw a filter to the hose connector as sand particles and other trash can clog openings in the Bi-Wall tubing. For installing Bi-Wall tubing, push it on the ear tee as far as it will go; push the collar outward, then grasp the Bi-Wall tubing and pull back on it while holding the ear tee in place with the other hand.
An emitter in sandy soil will water an area with a diameter of about 15 inches, while in clay soil the same emitter will water an area up to 2 feet in diameter. Repairing cut or punctured laterals is easy with a couple of connectors and a new section of tubing. Emitter systems with insets irrigate most uniformly when the pressure in the hose along the row is maintained in a range of 3 to 6 pounds per square inch. Ideal system operation applies just enough water to replace the amount used by the plants the previous day. And of course, a 48" outside width allowed me to cut the end cap pieces from just one timber, helping hold the cost down just a bit. Also the mulch will retain moisture that will be good to make waterings last longer and create a more real in the ground experience for your plants.
This may involve a french drain to move it to the street or any place lower where extra water won't be a problem. Move the sprinkler unit at regular intervals if the garden is larger than the sprinkler pattern. If only a small volume of water is available, water a few rows at a time and then change to a new set. Screens and filter cartridges need thorough cleaning or replacing periodically, depending upon the amount of foreign material in the water.
Since the same amount of water is released in both cases, the sandy soil obviously receives deeper watering than the clay. The widest spacing to use safely on vegetables and ground cover is closer than the narrowest required by tree crops. Uniform soil moisture content is maintained and the volume of moistened soil neither increases nor decreases. Then on top of the mulch add a layer of fertilizer, whether that is manure, peat moss, or compost. The rock in front of the weepholes means they can't work as designed and eventually won't drain at all. With caged tomatoes or trellised crops, set the sprinkler on a stand to allow the spray to arch up and over the top of the leaf canopy.
Wind does not carry water away as it can with sprinkler systems, and water lost to evaporation is negligible. This is kinda like the pest control companies that want to shove something like steel wool into the weepholes to stop buds but in reality they are putting an air filter in the weephole and it will plug up with fine dirt. If irrigating only one row with Bi-Wall, put a wide Bi-Wall collar on the hose connector, install it in the Bi-Wall and fasten it to a water hose or faucet just as for the header. It may be necessary to twist the locking collar to allow the Bi-Wall to go all the way up.) Work the locking collar down on the Bi-Wall, then hold the ear tee in one hand and pull on the Bi-Wall tubing with the other hand. That means the house is literally going up and down 16" from the wettest time of the year to the driest. If it leaks around the collar on the ear tee, push the Bi-Wall farther up on the eat tee, twist the locking collar again and pull on the tubing.
That's why it's recommended to water your foundation during the summer or dry time of the year. We can't control how wet it gets but we can control how dry to stop the house from being like an elevator.
