Basics of Raised Bed Gardening
Raised Bed Gardening is simply about creating structures for gardening that sit above the ground level. You can use raised beds for growing virtually any reasonably shallow rooted plants such as vegetables, fruits, herbs, flowers, etc. You can construct your raised bed garden from whatever materials you can readily and economically get your hands on. (For example: Untreated lumber, bricks, concrete blocks, rocks) Or, you can just create raised beds by building up piles of compost and dirt, without using borders for your garden
