You will need:
- dried seeds/pods
- a colander
- a bowl that the colander can rest in
- a hat or bandanna
- paper bags or envelopes (junk mail envelopes best if you want to feel resourceful)
- a magic marker
- a flexible mat, such as a kids' plastic placemat
- garden gloves
- a smooth, round stone or similar object
Seed saving is best outdoors in the shade in a place where you don't mind random veggies popping out of the ground en masse. You may want to wear gloves, especially for mustards, arugula, and other brassicas as the pods can be sharp. Place pods in colander on top of bowl (or mash entire bush in) and smash pods. Fully dried seeds will not mush while you pummel the pods. Once all pods are crushed, swirl the contents around with your hand to encourage reluctant seeds into the bowl below. Next is separating the chaff from the seeds. You may want to wear a hat. A very slight breeze can also help. Tip the bowl and gently blow the chaff (fibrous material you don't want). The hat is to keep you from looking like you've developed a clinical case of dandruff when a neighbor drops by unexpectedly. Oh yeah, you'd better close your eyes. Another option is to drop the mixture from about ten inches into the bowl and let the slight breeze help separate. Gently shimmying the bowl also forces the lighter chaff to the top, so you can skim it off. I've wondered if a blender or food processor could do some of this work for me, but I worry the seeds would get thwacked.
In the end, three radishes give me about 100 seeds. Label a paper bag (not plastic unless you're certain the seeds are dry; otherwise, you'll be sad when all your work goes moldy) with date and seed type. Carefully pour seeds into bag. Store in a cool, dry place. In a few months you'll probably be gripped by garden fever and go buy the same seeds. Oh well.
Other non-hybrid plant seeds that can be saved in similarly simple steps: beans, lettuce, broccoli, mustard, bok choy, kale, carrots, parsnips, parsley, cilantro, dill, celery, chard, and beets. Seeds from arugula, bok choy, mustard, lettuce, bok choy, broccoli and dill can be collected in the same season as they're planted. Carrots, beets, parsnips, onions and celery need to winter-over under a layer of leaves. They will form enormous bushes, so just choose one that looks the healthiest that's in a place you don't mind disappearing under 64 cubic feet (4'x4'x4') of biomass. Don't collect from one of these plants if it goes to seed in the first summer-this is an undesirable trait that you don't want to propagate. From the one kale I've collected seeds, I learned that they take two winters, but perhaps it was just an issue of the variety. For parsley, dill and cilantro, I allow a couple plants to drop their seeds and regrow.
