The humongous garden centers are always tempting, especially for small bedding plants and other things you need bunches of. Those nice supermarket prices help a gardener stay on budget. The problem, of course, is that the big box stores don't hire many garden-savvy staffers and their greenery sometimes turns brown a bit too soon. The Home Depot on Skillman seems to be the exception. Their plants are lush and healthy, and their garden department workers know a cactus from a philodendron. You'll leave here with nice plants that still have leaves weeks, maybe even months, later.
