Longtime organic gardener Jill Henderson explains how preserving open-pollinated and heirloom garden seeds from one season to the next will not only save gardeners money but will also increase their self-sufficiency and help them maintain a naturally diverse gene pool of food plants. Here are some of the many "insider tips" you'll discover: which seeds are easiest to save, why saving seeds preserves genetic diversity, easy hand-pollination techniques for beginners, the right way to harvest, clean, and store seeds at home, how to save hundreds of seed varieties from only seven crop types, how to ensure seed viability and test germination rates, and ways to keep seeds from cross-pollinating. Armed with these simple tips and instructions, anyone with a green thumb will find seed saving easy and rewarding.
