Q: I want to practice Landrace Gardening, in which the seeds to be planted the coming year come from the survival of the fittest in a particular garden in previous years. Where can I collect all the open-pollinated cultivars of edible crops I can grow on my land?
A: It’s an intriguing idea. Try Southern Exposure Seed Exchange (www.southernexposure.com) and Seed Savers Exchange (www.seedsavers.org). The South Carolina Crop Improvement Association sells heirloom seeds that have been passed along for generations. Details at https://www.clemson.edu/public/seed/heirloom.html.
