last year I had no luck with basil-- i planted them in miracle grow organic potting soil. 3 plants, and they just sat there. they grew tiny leaves, when they grew, but mostly nothing happened, all summer, until they bolted. This year I want to try to make my own mix-- I've been reading some of the recipes, but I am not clear about the ground bark. My source for this is home depot-- what kind of bark am I looking for? Pine? Cedar? Is there anything I should AVOID, since I half expect to get to home depot and they only have one option?
