It's garden-planting time. If you're an aspiring gardener, here's a must-read guide on Slate "for people with no gardening experience, very little experience, or discouraging-even completely traumatic-experience." It's a month-by month series by Constance Casey, who was a New York City Department of Parks gardener for five years. With humor and heart, she tells you the bare-bones basics, including what to buy at the garden store, how to prepare the bed, and how not to overthink it.
