If you misjudged your planting needs and purchased too many garden seeds, do not conclude the seeds are wasted. A frugal gardener can save seed packets for another year with careful storage. Most seeds you purchase in packets will keep for at least two years when you store them in the proper environment, according to University of Oregon Extension. Before you use saved seeds, test them for viability to ensure the seeds you plant will germinate and grow.
Reseal any seed packets that you already opened with the clear tape so the packets are securely closed. Another alternative is to place partially used seed packets in a plastic food storage bag, seal and label the bag.
Place the sealed and resealed seed packets into the container, filling the container with as many seed packets as you have or as will fit in the container. Place the lid on the container tightly.
Store the container in the refrigerator or freezer until you are ready to use the seeds.
