Some of you may recall that I went to Home Depot to find hardware cloth and
they didn't know what I was talking about. BRBR

are you planning to use hardware cloth to cover the drainholes in your bonsai
pots? I wouldn't recommend it. It may corrode before you get a chance to repot.
Why not use plastic?
