Best mulch for containers
I realize this question has probably been asked a million times, but what is the best mulch medium for container plants? I grow only tomatoes and peppers, and it gets hot and dry here in southwest Idaho in the summer.
I've read in some of the GW forums that organic mulch, like bark chips or old Maple leaves, encourage pill bugs and other pests. True? If so, what about sand as a mulch? Black or other colored plastic?
