WORK WITH OPEN-POLLINATED VARIETIES
The first step is to be sure you are working with the right types of plants. Though you can save seeds from both hybrid and open-pollinated plants (open-pollinated varieties are considered heirloom if they’re older than 50 years), you won’t get good results from hybrids. “In general, hybrids do not produce offspring from seed that’s the same as the parent plant,” says Torgrimson. “An heirloom will produce offspring that is ‘true to type’—that seed can be saved and planted. Hybrids are Russian roulette.” This is not to say that hybrids are “bad” plants—some hybrids, like the Early Girl tomato, are very popular and tasty. They are just not well-suited to seed saving. Seed catalogs and websites say whether varieties are open-pollinated (they may be marked “OP”) or hybrids; it may or may not be marked on the seed packets themselves.
LOOK BEFORE YOU EAT!
When you save seeds, you should always save from your best plants. That means the most gorgeous tomato you grow this year is not going on your plate. “There’s a temptation to eat the best,” says Leslie Land, “but if you stop and think about it, no, you must sacrifice.” She suggests saving seeds from the best three or four plants. How to decide? Arm yourself with a variety of colored twist ties and code them for different qualities. Mark the tastiest plants with one color, the best producers with another, the plants that yield earliest with another, and so on. Then save seeds from the plants that have the most desirable traits marked.
BROWN CAN BE BEAUTIFUL
Seeds you’re planning to plant for next year need to be fully mature, so you may have to adjust your gardening aesthetic to include the not-conventionally-attractive part of the growth cycle of the plant. “The plants at the end of their cycle are putting all their energy into the next generation,” says Terri Compost. Depending on what plants you are saving from, the plants and/or their fruit may need to be left alone to dry out, they might start looking scruffy when flowering, or they may even need paper bags placed over top of them in the case of something like lettuce—not what we think of as the quaint, perfectly manicured Martha Stewart vegetable patch. “People see gardens turning a little brown and think, ‘Oh, that’s unkempt!’ But you have to let it get a little brown to get into seed saving,” Compost adds. “Even the term gone to seed [should not be seen] as a derogatory.”
