Raised Garden Beds
The Benefits of Raised Bed Gardening. Raised garden beds, also called garden boxes, are great for growing small plots of veggies and flowers. They keep pathway weeds from your garden soil, prevent soil compaction, provide good drainage and serve as a barrier to pests such as slugs and snails
Are Pressure Treated Woods Safe in Garden Beds? Gardeners have used pressure-treated wood for decades in raised beds and as posts, but on December 31, 2003, the Environmental Protection Agency (EPA) banned the sale of lumber treated with chromated copper arsenate (CCA) for residential use.
The depth of the bed can vary. Six inches is a minimum. Plants need at least a 6- to 12- rooting zone, so 12 inches is ideal. Before you establish the bed, break up and loosen the soil with a garden fork so that it's not compacted.
my beds are 7-11.5 inch depth and either 24 inch or 30 inch height. Standard is 24 inch unless otherwise noted.
