This beginning class will start with the five easiest seeds to save and go step-by-step through the process. You will learn how to appropriately take care of the plants, select from your crops the best seeds to save, learn how to identify the best seed, care for them, harvest them and prepare them for saving and storing them. You’ll end up with stronger plants that are adapted to your own landscape. Once you can ensure your seeds are pure and true, than you can swap with others and to contribute to your community seed library.
