My friend’s community garden bed is close to trees and the plants seem to wilt very fast. He has peppers and broccoli planted. The broccoli that was taken from this bed had no roots when taken out of the ground, but there was no sign of bugs. There are 6 other people in the garden and they do not seem to have this problem as of yet. Could it be that he's putting on too much fertilizer or getting it on the plants?
