Raised garden beds, also called garden boxes, are great for growing small plots of veggies and flowers. By raising the soil level, raised garden beds also reduce back strain when bending over to tend the bed. Raised garden beds are available in a variety of different materials, or they can be made with relative ease. In most cases, cedar is the best wood to use for garden beds because cedar is naturally rot resistant. It is also important to consider the soil depth requirements for the roots of the vegetables you want to plant. Using a hand saw, cut the posts where they stick up, so that they are flush to the sides of the bed.
If your bed is longer than 8', or taller than 18", it's a good idea to use cross-bracing.
It's very helpful to have a 'spanner board', a short sturdy board, like a 2 x 6, that's just longer than the width of your beds. Raised beds are sturdy enough to support a trellis, even one large enough for pole beans which grow to 8' tall.
The fertile soil in your garden beds will attract the roots of nearby trees, depleting your valuable garden soil. Raised garden beds, planters, garden decks and outdoor wood furniture can be protected against both water and fungal-borne decay with new mineral-based formulations which are non-toxic, and safe to use with food crops. No-Till Gardening - how to improve production from your vegetable garden without digging into the soil.
Preparing your raised garden beds for spring - a few early spring tasks will help ensure a bountiful harvest.
You will need to decide what kind of wood to use, how tall you want the bed to be, and whether you want to build the entire bed yourself or use pre-made corner braces which simplify the construction process and provide a secure corner that won't work loose over time. Depending on the soil conditions beneath your bed, you may want to build the sides of your bed higher for certail crops. This is because it is easy to reach the center of the bed from either side, and for people with long arms, to reach across the bed. The method described here is, in our opinion, the simplest method of building a raised garden bed, and it requires no special tools or expertise. Two compounds, alkaline copper quat (ACQ) and copper azole (CA-B), have now replaced CCA wood in the residential market. If you plan to grow root crops, such as potatoes or carrots, you may want to set the mesh lower in the ground by digging deeper when you are setting up the bed. This board can be laid across the bed, setting on top of the bed sides, and can be used to set buckets on when weeding or adding amendments, and it can be used to step on if you must step on the bed. When laying down the landscape cloth, allow it to come up 1" against the bottom board of the bed, and staple this to the bed. Here is our favorite trellis design which won't mark your raised bed with visible holes, yet is easy to disassemble for storage or to relocate to another raised bed.
If there are trees adjacent to your beds, you may want to consider installing a root barrier. The sides of the beds keep your valuable garden soil from being eroded or washed away during heavy rains. And if the beds are built well, the gardener can sit on the edge of the bed while weeding, and for some gardeners this is the biggest benefit of all.
Planter bottoms usually are slatted, with some type of semi-permeable cloth barrier which permits drainage.
If you have good soil beneath the bed, the roots will go down deeper as needed to access more soil and nutrients, so you can even have beds that are only 6" high. It's important to keep the width this narrow to avoid having to step on the bed since this would compress the soil.
If your bed is aligned the other way (the ends facing south), you may have planting limitations because taller plants in front can block the sunlight to small plants in back.
In many regions, gardeners are able to plant earlier in the season because the soil is warmer and better drained when it is above ground level.
Raised beds, however, do not have bottoms; they are open to the ground, which offers the benefit of permitting plant roots to go further into the ground for available nutrients.
If you want a taller bed, remember that as you go taller, the weight of the added soil will add pressure to the sides, and will bow them outward.
The bed can be any length as long as cross supports are installed every 4' - 6' along the length of the bed to prevent bowing. The copper keeps insects at bay, and the fungicide prevents soil fungus from attacking the wood. These planters are designed to be easy on the back, but they also keep burrowing pests, rabbits, cats and other critters out of your garden. We recommend using cross-supports in any beds which are taller than 18", or longer than 6'.
