I'm trying to figure out why the tomato plants in the raised bed in my driveway aren't doing well. The soil is good, I water, the weather here is a bit foggy and cool but not terrible, the other plants I've tucked in the bare spots (lettuce, basil, cilantro) are doing fine, but the tomatoes lack oommph. There *are* a few potatoes that i missed popping up here and there and I vaguely remember reading that tomatoes don't like them. Am I crazy? Could potatoes stunt tomatoes? (I know they're both in the nightshade family.) Oh, and I'm growing several types of tomatoes -- from early girls, to Roma, a couple heirlooms, a cherry.... and they're all growing slowly and producing no more than a couple of fruits at a time.
