Seed packets have a tendency to get lost in the shed or garage, hidden among gardening tools and bags of potting soil. Keep track of your seed inventory, and help protect next year's crops by properly storing packets in glass jars or boxes neatly labeled with index cards and divider tabs. Sealable sandwich bags are also good for storing seeds. If you store yours in jars, include a moisture-absorbing sachet. To make one, wrap 2 tablespoons of dry, unscented cat litter or powdered milk in a double layer of tulle or cheesecloth; secure the bundle with string. Store your organized seeds in a cool, and plant them within the next two years.
