Swap seeds with other gardeners and learn how to care for them properly at the 13th Annual Seed Celebration & Swap, hosted at the Old Stone House in Park Slope. Learn why preserving heirloom and organic seeds are important and receive compost training, too.

Check out High Mowing, Fruition, John Scheepers Kitchen Garden and Baker Creek Heirloom Seeds -- they're giving seeds out for free.

Hudson Valley Seed Co. Art sells organic seeds in beautifully designed packets, so check them out too.

Fedco Seeds will share their organic seeds, but you'll have to bring your own bag if you want to bring some home.

Visit Blue Lotus Botanicals for their soaps and healing creams and don't forget to take advantage of the many free catalogues and expert instruction on your way out.
