Filling a raised bed

Volume is length × width × depth. Fill most vegetable beds 10–12 inches deep. Buying bulk by the cubic yard beats bags once you pass ~15 bags.

FAQ

What soil mix for a raised bed?
A popular blend is roughly 60% quality topsoil, 30% compost, and 10% aeration material like perlite. Avoid filling with pure bagged "potting mix" (expensive) or pure topsoil (too dense).
