The Benefits of Raised Bed Gardening
Raised garden beds (also chosen garden boxes) are great for growing small plots of veggies and flowers. They keep pathway weeds from your garden soil, preclude soil compaction, provide expert drainage, and serve as a barrier to pests such equally slugs and snails. The sides of the beds proceed your valuable garden soil from eroding or washing away during heavy rains. In many regions, gardeners are able to plant earlier in the season considering the soil is warmer and better tuckered when information technology is in a higher place ground level. Raised beds are also ideal for square pes gardening.
Raised garden beds are available in a variety of different materials, or they tin be made with relative ease.
By raising the soil level, raised garden beds as well reduce back strain when bending over to tend the bed. This is especially helpful for older gardeners or people with bad backs. And if the beds are congenital well, the gardener tin can sit down on the border of the bed while weeding. For some gardeners this is the biggest benefit of all.
Raised beds are non the same every bit garden planters. Planters are elevated containers which have bottoms to prevent the soil from falling out. Planter bottoms usually are slatted, with some type of semi-permeable textile barrier which permits drainage. Raised beds, however, do non have bottoms; they are open to the ground, which offers the benefit of permitting plant roots to get farther into the ground for bachelor nutrients.

How to Build a Raised Garden Bed
Edifice elevated beds for your vegetable garden is simpler than information technology looks. Yous'll demand to decide what kind of woods to employ, how alpine yous want the bed to be, and whether you desire to build the unabridged bed yourself or utilise pre-made corner braces. These simplify the construction process and provide a secure corner that won't loosen over fourth dimension. Yous tin likewise use concrete blocks or other materials for your beds, but woods is toll constructive and readily available.
What Kind of Woods to Use?
In most cases, cedar is the best wood to use for garden beds because cedar is naturally rot resistant. Western red cedar is unremarkably used, but white cedar, xanthous cedar and juniper are too high-quality choices for outdoor construction projects. Redwood is another excellent rot-resistant forest, but redwood is a more limited resource. How long the woods volition last depends on the type of cedar and your local weather conditions. In our garden, we use red cedar for building the beds, and some of these beds take lasted 15 years.
How Tall Should the Bed Be?
You can build the bed to any desired acme up to 36″. The near common height is 11″, which is the height of two stacked 2″ ten 6″ boards. If yous accept good soil below the bed, the roots will go downward deeper as needed to access more soil and nutrients, so yous tin can even have beds that are only 6″ loftier. If you want a taller bed, remember that as you become taller, the weight of the added soil will add pressure level to the sides, and will bow them outward. This is hands prevented past including cross-supports. We recommend using cantankerous-supports in any beds which are taller than 18″, or longer than 6′. It is as well important to consider the soil depth requirements for the roots of the vegetables you want to establish. Depending on the soil conditions below your bed, you lot may want to build the sides of your bed college for certail crops. For more data, read our article Soil Depth Requirements for Popular Vegetables.
How Wide and Long Should the Bed Exist?
We recommend bed width to be no wider that 4′ across. This is because it is like shooting fish in a barrel to reach the center of the bed from either side, and for people with long arms, to reach across the bed. It's important to go on the width this narrow to avoid having to step on the bed since this would compress the soil. The bed can be whatever length every bit long every bit cantankerous supports are installed every 4′ – 6′ along the length of the bed to preclude bowing. Nosotros call up longer beds are best, if you lot accept the garden space.
We take congenital many beds over the years, and our structure procedure has evolved. The method described here is, in our opinion, the simplest method of edifice a raised garden bed, and it requires no special tools or expertise. Using this method, y'all can build your bed to whatsoever desired length, width and meridian.
Tools & Materials
Lumber
Use cedar "2 x" boards for the sides. These are usually two″ x 6″, but y'all can use 2″ x 4″ or ii″ ten 8″ boards if this is what yous take available. (2″ boards bought at a lumber yard are actually i.v″ thick..) For the corner posts, use 4″ 10 4″'s, cut to x″ longer than the desired height of the bed. If your bed is going to be longer than 8′, you'll need extra posts to put in mid-span to prevent bowing and to provide a place to secure the cross-supports.
In the photos below, nosotros used ii″ ten 4″ boards for the posts instead of 4″ 10 four″s. This is because the wood we had was full dimension, i.e., the 2″ thickness was a full 2″. If y'all get your wood from a manufactory, they can cut information technology full dimension for you lot.
Fastenings
Utilise 3.5″ #ten coated deck screws for the project. You'll demand six screws for each corner and ii for each mid-span mail. If you are using cross-supports, go a few 1″ stainless screws.
Cross Supports
Buy several lengths of one/2″ aluminum apartment stock. This is bachelor at most hardware stores, normally in eight′ lengths. Information technology is very easy to cutting with a hacksaw and to drill for the screws.
Tools
Hand saw, square, carpenter's level, mallet (or sledge), screwdriver, hacksaw, drill.
Is treated lumber safety?
In 2003, the EPA banned the sale of lumber treated with chromated copper arsenate (CCA) for residential utilize. Two compounds, element of group i copper quat (ACQ) and copper azole (CA-B), have at present replaced CCA wood in the residential market. Both incorporate copper and a fungicide but no arsenic. The copper keeps insects at bay, and the fungicide prevents soil fungus from attacking the forest. In ACQ, the fungicide is quat, which is also used in pond-pool chemicals and as a disinfectant. The other compound, CA-B, uses copper and tebuconazole, a fungicide used on food crops. According to Miles McEvoy, who works in organic certification with the Washington State Department of Agriculture, no pressure level-treated wood is allowed in soils used to abound organic food. If y'all want to meet this high standard, choose a different material.
Until the safety of treated wood is proven conclusively, nosotros recommend yous use a naturally rot-resistant wood like red cedar, black locust or redwood. Under almost circumstances, these woods volition terminal 10 – xx years. Recycled composite plastic lumber is another culling, and is at present available in a variety of sizes and colors.
Construction
Installation Tips & Layout Suggestions
Lay out the beds and then they are horizontally facing south
It's all-time if the long side of the bed faces due south. This assures equal low-cal exposure to all the plants growing in the bed. If your bed is aligned the other manner (the ends facing south), y'all may take planting limitations considering taller plants in forepart can block the sunlight to small plants in back.
Double-dig the bed area
If the ground has never been used for gardening, it should be 'turned over' (dug) to a depth of sixteen"". This gives y'all a chance to pull rocks, and to see the limerick of your soil. Leave soil piled up in the center, away from the sides, so yous can set the bed in place without obstructions.
Level the bed
Utilize a level for this job. This may seem overly meticulous, but after several waterings the soil volition settle to level, and you''ll desire the bed to be the same. Ready a stiff board (2×four) on top of the bed sides, across the span, and fix your level on this lath. Tap down the sides equally needed till you get a level reading. Be sure to check for level both along the length and beyond the width of your bed.
Check for roots
As you dig the soil, proceed an eye out for any roots which may be growing below your beds. If left to grow, these roots volition steal the organic amendments you add to the soil. Pull whatsoever roots back towards their source, and pull the main root clump. If the source is a living tree, you may need to install a root bulwark by excavation a narrow trench outside the perimeter of the bed, and deeper than the roots, and and so insert a barrier such as heavy plastic sheeting.
Avoid stepping on the bed
Once the soil is added and the bed is planted, make it a policy to never step on the bed. Stepping on the bed will compact the soil, reduce aeration and impact root growth. Pets should also be trained to stay off the raised beds.
It's very helpful to have a 'spanner board', a short sturdy board, like a ii x half dozen, that's merely longer than the width of your beds. This board tin be laid beyond the bed, setting on top of the bed sides, and can be used to set buckets on when weeding or calculation amendments, and information technology can be used to step on if you must stride on the bed. It also makes a handy seat when weeding or tending the bed.
Burrowing pests?
If your garden has burrowing pests such as moles, a layer of 1/2″ or i/4″ hardware cloth (galvanized mesh) can exist laid beyond the bottom, before soil is added. The mesh should continue at least 3″ up forth the insides of the bed and exist stapled in place. If you plan to grow root crops, such as potatoes or carrots, y'all may want to prepare the mesh lower in the ground by digging deeper when yous are setting up the bed. There are also planters available for in a higher place-basis gardening. These planters are designed to be easy on the back.
Spread soil out evenly
Add any planned soil amendments, such as peat, compost or lime, and spread the soil evenly across the bed. Water the bed with an even, fine spray. This volition settle the soil; add more soil to "tiptop off". (Over time the soil volition settle an inch or two more.) Rake the bed again to even out the soil and y'all''re set up to institute.

Go out a generous width betwixt beds for the pathways
It helps when pathways between beds are wide enough for a pocket-size wheelbarrow. For grass pathways, make certain they are at to the lowest degree wide enough for a weedeater or a pocket-sized mower. (In our raised bed gardens the pathways are 22″ wide.)
Mulch the pathways between beds
Weeding pathways is a nuisance that yous tin avoid by putting a double layer of perforated landscape cloth over the pathway and roofing this with a 2- three″ layer of bark mulch or coarse sawdust. When laying down the landscape fabric, allow it to come up up ane″ against the bottom board of the bed, and staple this to the bed. This will not be visible because the mulch will encompass it.
When buying mulch, ask the seller if they have had whatsoever complaints about weed seeds in the mulch. Information technology'due south very common for bark mulch to take weed seeds that sprout in your pathways. Some weeds will still announced on your pathways regardless of the mulch. Look until it rains before pulling them out or you might rip the landscape textile. The weeds will come out hands if the ground is wet.
Tin can a raised bed be installed on a concrete surface, such as a patio? Yes!
Many beautiful raised bed installations are assail concrete surfaces, but there are a few things that need to exist taken into consideration. Typically, patio and driveway surfaces are non level. This is intentional so water can drain away from the principal firm structure. Raised beds, all the same, should be built to level, the same as if being synthetic on soil.

How to Irrigate Raised Garden Beds
Types of Irrigation
There are many ways to water a raised bed. Each one has a diverseness of pros and cons.
- Drip Irrigation: A network of hoses with emitters or holes that allow h2o to baste out slowly.
- Soaker Hose: A porous hose that leaks or soaks water out forth its unabridged length.
- Sprinkler: A device with holes hooked to the stop of a hose that sprays water through the air.
- Manus Watering: Watering with a sprayer or other nozzle by hand.
- Wicking: Filling a porous reservoir under the soil that wicks water slowly into the soil, with a specially built garden bed or archaic olla pot.
| Irrigation Method | Price | Labor | Installation | Effectiveness |
|---|---|---|---|---|
| Baste | Relatively expensive | No piece of work during watering | More work to install | Very precise, saves water, prevents affliction |
| Soaker Hose | Relatively inexpensive | No work during watering | Less work to install than drip | Gaps possible, saves water, prevents disease |
| Sprinkler | Inexpensive | Some light piece of work to motion sprinklers | No piece of work | Covers everything, including areas that may not demand water |
| Hand | Very inexpensive | Time intensive | No piece of work | Targets desired areas |
| Wicking | Somewhat expensive | No work | Lots of work to prepare | Very precise |
Installing Irrigation
The goal of any irrigation system is to make sure every plant gets enough water to thrive. With each method of irrigation there is a different strategy to run into this goal: for dripping and soaking, hoses must be placed in the right locations to fully water the desired plants. Additionally, the holes in your drip lines must be spaced according to your plant's needs.
When spraying, whether with a sprinkler or by hand, you must also consider duration. Calculation an automatic timer to your watering organisation will help remove the guesswork. Fifty-fifty better, a raised garden bed makes irrigating your crops simpler because drip record and soaker hoses tin be mounted to the side of the box to keep them immobile. The most mutual mistake when irrigating is leaving gaps. Exist certain to measure out the accomplish of your hose against the size of your box and install enough lines to thoroughly soak the soil.
How Ofttimes to Water
If the soil is dry 1 inch beneath the surface, it'due south time to water. Raised beds demand to be watered a little more than frequently than traditional, in-ground beds because they drain faster and tend to encourage rapid establish growth, which requires more than water. In the summertime, this might mean watering multiple times per day depending on the stage of plant growth and the type of ingather. In general, it'southward better to water deeply a few times per calendar week than more frequent, shallow watering.
Should I Automate My Watering Organization?
Automation works best with a drip line or soaker hose organization. Putting your hoses on a timer ensures that you won't forget to water when your plants most need it, and saves your ingather when yous are vacation. Automating your system besides allows you lot to fourth dimension watering for the cool of the evening or the middle of the night when the evaporation rate is lowest.

Conserving Irrigation Water
If you lot are using drip tape or soaker hoses, you've already taken a large step towards conserving water. Yous can take this a little further by mulching on summit of the hoses around your plants to farther reduce evaporation. Routine maintenance of your arrangement should also include checking for leaks, which are oft caused by creatures looking for h2o (or errant pitchforks). Y'all can prevent leaks at joints past making sure there is proper water force per unit area for the system you are using, and that all joints are sealed. It'south also a good thought to install shut-off valves for each bed or garden section and so that you can choose to h2o some beds less when your growing season is winding upwards or down.
Raised Bed Watering Tips
