A: Given perfect soil, different vegetables send roots to different depths. Lettuce, radish, basil and spinach grow fine in soil only 4 inches deep. Beans, pepper, eggplant and carrots need 8 inches of soil or more. Tomatoes, okra, corn and summer squash can use a full 12 inches of soil. My advice? Use 8-inch-wide boards to build the frame, then thoroughly shovel the soil under the frame 6 inches deep. Add three 2-inch layers of bagged soil designed for outdoor raised beds, thoroughly mixing each layer with the one(s) beneath. That should give you 12 inches of soil depth, which is adequate for all vegetables.
Q: I saw that Truist Park uses paspalum grass. Our zoysia lawn struggles in an area shaded by some oak trees. Would paspalum have more success? Robert Twilling, Cartersville
A: I don't recommend it. Paspalum grass can look very good as a turfgrass but requires more maintenance than zoysia. It will require frequent mowing, and you'll need a reel lawnmower to keep the mowing height low enough. Zoysia and paspalum are about the same in shade tolerance.
Q: My Florida room leaked over the winter and mushrooms grew in the damp carpet. Could you tell me someone who could identify them? Ed Carter, email
A: I am far from a mushroom expert. When I am curious about a mushroom that I have found, I go to the Facebook group formed by Mushroom Hunters of North Georgia, bit.ly/GAmushroom. It is easy to join their group and post pictures of mushrooms you want to identify.
