Raised bed gardening offers many advantages over traditional "in the ground" gardening. This simple technique will improve the health and productivity of your garden while bringing the soil up to a comfortable working level. Raised container gardens are perfect for people with limited space, or who have a hard time bending over and kneeling on the ground for traditional gardening.
Improved plant growing conditions, larger harvests, accessibility, and improved garden pest protection are just some of the advantages of this gardening method. Raised bed gardens also are more efficient in fertilization and water conservation. Gardening in raised beds simply means that you grow your plants above the level of the ground. Plants cover the bed areas; gardeners work from the paths.
When creating your container beds, make them only as wide as can be easily worked from either side. Typically, the beds are constructed 3 to 4 feet wide and elevated between 8 inches and 2 feet. Taller raised beds allow gardening without much bending. While you're building, why not add benches on the sides for even more convenience! Spaces between beds may be left in sod, mulched or even paved with stone or brick. In a vegetable garden, leave enough room for a wheelbarrow.
Wood, brick, rocks, or cement blocks are all popular materials for making a raised bed. Wood is the most common choice, because it is easy to work with and it is inexpensive. The best wood choices are durable materials such as cedar, cypress or redwood. With tall beds made of wood will need support so that your bed will hold up the weight of the soil. You can also use rebar placed into the ground around the edges of the bed to support the wood. My cedar raised beds have attracted a decade, and are still in use.
With this gardening method you can basically start from scratch and create the soil environment that best suits the plants you would like to grow. Soil building is an important part of any garden and it's much easier to control that aspect of gardening with raised beds. The bed is a clearly defined area where the gardener can concentrate on soil improvement techniques; for example, adding compost or fertilizers. Poor soil can be adjusted or replaced completely in a raised bed, so you can eliminate soil borne diseases and improve the ability to hold an appropriate amount of moisture. You can fill the bed with your own mix of soil if the natural soil in your area is not that good for gardening.
Soil preparation is the key to successful intensive gardening. It's important to realize that soil compact can reduce crop yields up to 50 percent. By eliminating walking on the soil, water and air can more easily penetrate the soil. The basic idea of a container garden is that instead of battling against poor soil conditions, you build above ground, where you can have absolute control over the soil texture and ingredients.
Soil in raised beds warms faster in the spring compared to ground soil by as much as 15 degrees. It's a simple task to create a mini greenhouse with raised beds, by supporting a tunnel of clear plastic over a bed. Plants may be grown more closely together and then they will crowd out weeds and shade the soil, reducing evaporation and keeping roots cooler. Fertilizer, compost and manure can be concentrated in the small garden area, so plants may be spaced closer together.
In raised beds, it is easy to control weeds with plastic mulch economically, since the width of the bed can be spanned by one roll. Garden pests and weeds are also easier to control, making your gardening experience less stressful. Plants are elevated to a convenient working level, making them easier to tend and enjoy. It also reduces stooping and back strain by bringing plants about a foot closer to you.
Raised beds produce a variety of benefits: they extend the planting season; they reduce the need to use poor native soil; and they can reduce weeds and some pests if designed properly.
Gardening can be a great activity for individuals with disabilities, with some consideration to the special needs of the gardener. Raised bed gardening, space efficient and attractive, presents a secure and valuable area for your plants, vegetables, and flowers to thrive. Whether for aesthetics or accessibility, modern gardeners are rediscovering and enjoying this centuries- old technique.
