Concerned with seed saving? Earlier than getting began, it’s vital to know the distinction between storing moist seeds and dry ones.
The next excerpt is from Will Bonsall’s Important Information to Radical, Self-Reliant Gardening by Will Bonsall. It has been tailored for the net.

Dry vs. Moist Seeds: Amassing and Storing Seeds
Determine 6.12. In the event that they’re introduced indoors earlier than exhausting freezes, cucumbers can proceed to after-ripen for a couple of weeks earlier than processing to enhance high quality.
Probably the most often requested seed-saving query is: How can I inform when seed is mature sufficient? Essential, since immature seeds is not going to retailer properly, nor will they germinate.
We should do not forget that “maturity” for our functions implies that the seed germ has developed totally; the seed could seem full-sized however nonetheless be succulent and underdeveloped (leek seed is an instance).
Seed-Saving Ideas
Steadily in seed saving you can not have your cake and eat it, too—you get seed or meals, not each. Nevertheless there are a number of exceptions.
For instance, cukes (cucumbers) and zucchinis are eaten within the immature stage, and people you want to save for seed have to be left to ripen manner past usefulness as meals.
However winter squash and pumpkins are eaten at full maturity anyway, so your seed squash are additionally meals squash and vice versa (offered you’ve stored them pure).
In reality the standard of squash seed improves with storage within the fruit—after-ripening, it’s referred to as— so it’s finest if you happen to don’t course of all of them at harvest, however scoop out and save the seed of every fruit as you utilize it.
Sooner or later nevertheless, relying on selection, seeds could begin to sprout contained in the intact fruit.
Working with Dry Seeds
Seeds are generally labeled based on their processing methodology: moist or dry. Most are dry and are processed by a mix of strategies referred to as threshing and winnowing. For these seeds their diploma of dryness is a measure of their maturity.
You should buy gadgets for measuring the seeds’ moisture content material, however for our functions it’s simple to find out properly sufficient by following this primary rule of thumb: Are the seed and its environment (pod, bract, et cetera) brittle and crumbly?
Measuring Moisture Content material
For instance, do the pods crack somewhat than bend like leather-based? Does all of the trash crumble into mud and stuff that may be blown away? If not, go away the crops till they’re totally mature. If rain wets them allow them to dry out once more.
If frost threatens and also you’re not sure whether or not the bean seeds are prepared (in contrast to pea seeds, damp beans could be ruined by heavy frost), then you will need to decide: Are you able to cowl the crops to guard them by means of that frost or must you harvest them, despite the fact that the pods are a bit leathery?
If you happen to go for the latter, it’s higher to tug the complete crops, roots and all, somewhat than decide pods. The seeds could possibly draw a bit extra life power from the dad or mum plant, simply sufficient to complete their ripening.
Subsequent time plant earlier or use some season-expanding technique, so you’ll not have this concern.
Managing Mature Seeds
What about overmature? Usually overmature is a meaningless time period, like jumbo shrimp or trendy artwork. If seed is mature it’s simply mature, that’s all.
Nevertheless there are issues lest it ought to shatter onto the bottom, an actual difficulty with brassicas and parsnip, or be eaten by birds, notably composites like salsify and sunflower.
And if seed stalks sprawl over in order that the seeds or pods are on the moist floor, they might both rot or sprout. However the seed itself can’t get “too ripe.”
Avoiding Potential Issues
I’ve developed a number of methods for avoiding the above-mentioned issues. Once I discover brassica seed stalks which have reached the shatter-prone stage, I go away them alone till the subsequent morning.
The seed is not any much less mature then, however the pods can have taken up a slight dampness through the night time hours and could be dealt with with little or no loss.
I acquire them by stripping the pods from the stalks into a big paper bag and even simply clipping off the entire stalks or crops in the event that they’re not too badly tangled. I go away this bag opened to the air till the pods are as dry as they had been the earlier afternoon after which proceed to course of them.
When salsify seed is ripening I cowl particular person heads with scraps of gauze, however solely after pollination is lengthy over. In excessive instances of persistent moist climate I’ve lined crops with some type of cover, however that’s very uncommon; what will get moist will dry out once more.
Working with Moist Seeds
The “moist” seed crops, people who maintain the seed inside a succulent fruit, like tomatoes, peppers, squash, and cukes, require a considerably totally different strategy. For every of those fruits there are barely totally different clues to find out when seeds have reached maturity.
Tomatoes and Peppers
A tomato must be ripe sufficient for consuming or, higher but, overripe to the purpose the place you may hurl it at a clumsy performer or political opponent. Very not often will a fruit ripen a lot that the seed sprouts inside it.
Regardless of what I mentioned earlier about underripe seed, tomatoes and peppers are considerably extra forgiving. I’ve frequently harvested inexperienced tomatoes, full-sized and glossy however inexperienced nonetheless, and ripened them in a sunny window, at which level the germ was totally developed.
Likewise peppers: Ideally peppers ought to have turned their mature color (normally pink, however generally yellow or chocolate brown) on the plant, however once more, I’ve been pressured by early frost to select them inexperienced or half inexperienced and after-ripen indoors, fairly efficiently.
Cucumbers and Zucchini
Determine 6.13. Scrape the innards of cucumbers right into a bucket or different container in which you’ll ferment the seeds. {Photograph} courtesy of Joe Hodgkins.
As for cucurbits clearly a cucumber or summer season squash on the consuming stage is ineffective for seed. The cuke have to be left to turn into a deep yellow-orange blimp or higher but brown and netted like a melon.
As for zucchini you realize these big inedible prizewinners on the honest? You get the image.
With cukes and tomatoes you may have a clingy goo that consists of amniotic sacs, very like frogs’ eggs in perform and look.
You possibly can merely unfold the entire enterprise out on a rack or paper towel and it’ll finally dry, however that might be an enormous mistake.
Retaining Moisture: Detrimental or Optimistic?
You see, that gelid stuff is designed to retain moisture, which could be very useful for seeds which might be anticipated to germinate within the quick time period however not for seeds which will want to stay dormant within the packet for a number of years.
It additionally offers an excellent medium for the expansion of varied illness spores, such because the fungus that causes damping off in seedlings. Hmm! May simply be a good suggestion to do away with that stuff, however how?
Letting Fermentation Do the Work
It turns out that goo is well damaged down by a quick fermentation, which not solely doesn’t hurt the seed however truly leaves the seed coat impregnated with a number of antibiotic and probiotic stuff that really protects the seed from these dangerous cooties. How simpatico!
Market seed is normally de-gelled by exposing the seed to an answer of hydrochloric acid. That sterilizes the seed coats however destroys all that probiotic profit. {The marketplace} doesn’t have time to let nature take its course, however maybe you do.
How a lot time does it take to ferment seeds to the suitable level? A number of days; some say till traces of mould dot the floor, others say when fruit flies begin to take word; I say when your vital different yells at you to “Get that stuff out of right here!”; that’s a reasonably dependable indicator.
Managing the Seed Combination
When your combination reaches that important level take the bowl or cup of ugly glop and put it in a glass jar together with a number of instances that quantity of water. (I often develop cuke seed commercially, during which case I exploit 5-gallon plastic, or 18.9 l, pails.)
Stir the combination properly, breaking apart lumps along with your pinkies—sure, your palms will scent gross, nevertheless it goes away in a couple of weeks. If you happen to favor, use a long-handled spoon.
Because it swirls round within the jar you’ll discover some stuff swirling round to the underside and different stuff swirling round to the highest.
Floating Seed
The underside stuff is especially plump seed with a few of the denser pulp following it, particularly bits of pulp hooked up to seed. The highest scum is usually gas-filled pulpy fibre. If there are seeds blended with the floating crud, both they’re hooked up to some light-weight pulp or the seeds themselves aren’t any good, stuffed with buoyant fuel; no loss there.
Determine 6.14. This bucketful of fermented cucumber seed is simply gross sufficient to be processed.
Particularly with cucumbers I at all times have a number of floating seed; it’s alarming to see such good plump-looking seed getting poured off with the scum.
If you happen to want reassurance avoid wasting out and dry it individually: See the way it shrinks to hole hulls that blow away at a puff. The plumpness, like a child’s smile, was the results of fuel.
Ending the Fermentation Course of
Don’t be fanatic with this primary decantation; be glad with pouring off half of the cruddy slurry. Then repeat the method many times; every time the cruddy liquid will turn into thinner and clearer and the great seed will sink sooner (it was barely buoyed up earlier than by the denser soiled water).
When the water is clear sufficient to swimsuit you, put the seed in a strainer and provides it a final chilly rinse earlier than spreading it out on a tray or display to dry.
Storing Completely different Varieties of Seeds
Enable a number of days to be on the secure aspect. As with every seeds too lengthy is best than not lengthy sufficient, offered they’re secure from mice. The fuzzy tomato seeds will kind clumps which might be simply “singulated” by rubbing between your palms.
Cucumber seeds will retain a dry residual movie that’s simply sloughed off and blown away, however beware: The seed ends can jab your palms nastily if you happen to rub them exhausting. Identical with melons, though they don’t should be fermented, nor do dry-processed squash or peppers.
As with tomatoes and peppers the ripe seeds of cucurbits proceed to attract some life power from the placenta. Regardless that the squash fruits could also be totally mature at harvest, the seed is additional improved if you happen to go away it within the fruit in storage for a number of weeks earlier than scooping out the seeds.
