Saving seeds is sustainable and saves money. It also helps strengthen plants as
they adapt to local conditions and it preserves your favorite heirloom
varieties. Many gardeners love to share or swap their seeds with other
gardeners. In this light, we can learn a lot about seed saving from Small-Scale Market Gardening (SMG),
which is all about keeping
things sustainable, encouraging variety, space-saving, and sharing among gardeners. This process helps plants become stronger and better suited to their local
environment.
How to Save Seeds
Start by selecting healthy,
non-hybrid plants.
Allow fruits and vegetables to mature fully on the plant before harvesting. Wet seeds, like
tomatoes, should be separated from the fruit, rinsed, fermented, and
then dried. Fermenting helps remove the
gelatinous coating that sometimes inhibits germination. Simply put seeds in water for a few days until a layer of mold forms, which helps break
down the coating. After fermentation, rinse the seeds well and dry them. Dry seeds, like beans and lettuce,
need to be removed from pods, separated from chaff, and dried. Store dried seeds in labeled envelopes or airtight containers in a cool,
dry place to maintain their viability. If you want to be especially crafty, you
can use pre-made templates to make your own seed packets!
Concerns About GMO Seeds
Home gardeners sometimes worry about exchanging seed with other gardeners because they don't want GMO contamination. GMOs are
not likely to be found in your home garden because no retailer sells genetically engineered seeds to home gardeners. GMO crops are expensive and commercial farmers are required to sign a contract that protects the
patented technology. These companies do not sell GM-crops to the home garden
market or to garden centers.
- Tomatoes & Peppers are self-pollinating and easy to dry.
- Beans & Peas should be allowed to dry in their pods before you harvest them.
- Lettuce produces abundant seeds and is easy to grow.
Other Things to Consider
Be sure to prevent cross-pollination by isolating certain plants like squash, pumpkins, cucumbers, melons, and corn to maintain pure seed varieties.
