Depth, filling, soil types and ordering.
Measure the inside of your raised bed and choose a soil depth, then work out how many bags or cubic yards to buy.
Compare bagged and bulk soil for the amount you need, including minimum orders, delivery and getting it into the beds.
At least 10 inches of soil for most crops, 15 to 18 inches where nothing usable lies below, and the root depths of common vegetables, with what each depth costs to fill.
On open ground, usually nothing but soil: no gravel, no plastic. What cardboard, hardware cloth and landscape fabric are for, and when a bed needs them.
Extension services agree on topsoil plus compost, from two parts to one up to equal parts. The recipes side by side, what to avoid, and the bags each takes for your bed.
What each bag or load actually is, which one a raised bed, a pot or a lawn needs, and the labels that do not mean what they seem.
Deep beds eat soil. What extension services say about filling the bottom with branches and logs, how much soil it saves, and the settling and nitrogen costs.
Yes: keep the soil and top it up with compost each year. How many inches extension services give, what that is in bags for your bed, and when to replace the soil instead.
A cubic yard of topsoil weighs 2,200 to 2,600 lb for the suppliers we list; mulch about 500 to 600 lb, gravel 2,440 to 2,700 lb. How many barrow loads and car or pickup trips that is.
