A few years ago I planted some lettuce seeds in November and they came up nicely in the Spring, but since then they haven't done so well. Has any one had success? Lettuce, green onions, or other? If volunteer tomatoes come up on their own it seems like they and others might do well. Mulch with leaves like i do with garlic ? I would like to develope a system. I have bought some row clotches to use in the Spring. Thanks.
