It seems that common consensus is that gardener is either born with a green thumb or not. I think a green thumb is learned, and I’m going to tell you the secret! (Okay, maybe it isn’t really a secret, but it sounds good.)
My great-grandfather felt that everyone should have a garden. Anytime he went to visit someone that did not have a garden, he put one in. This weekend I thought of him often when I took a little unused patch of the backyard at my in-law’s house and turned into a vegetable garden.
