You will have fewer problems with pests gardening in raised garden beds. If you have had previous problems with burrowing rodents, a lining of chicken wire in the bottom of each will eliminate them. Weed control is much easier handle because you can walk around a raised bed without having to bend over to pull out, if you have any weeds at all.
This also makes more space available for intensive crop production. They can be created over large areas with the use of several commonly available tractor-drawn implements and efficiently maintained, planted and harvested using hand tools. This form of gardening is compatible with square foot gardening and companion planting.
When growing vegetables in raised garden beds using the Square Foot Gardening method, your beds will need to be sectioned off into one-foot sections called planting squares.
A 4x4 foot garden bed, for example, will have 16 planting squares (because there are 16 square feet in a 4x4 bed). A 4x8 foot garden bed will have 32 planting squares.
