My spring garden worked out really well, but things kind of died in the summer—yes, my beloved tomatoes died, and the cucumber too. All I have going now is basil and a half-hearted parsley plant.
But I replanted, and we'll see if the peas and radishes and lettuce and whatever else I planted but can't remember come up. I figured it would be better to plant and see what happens than to keep planning on researching first and then never getting anything done.
Oh, and one thing that works well (so far): mulching thinly over the dirt to keep moisture in. I just used grass clippings.
