Seed saving is essential to a sustainable future. Here are some helpful tips.
I don’t know if this has happened to you too, but there are few things more frustrating than having a beautiful harvest, putting it away feeling pretty proud of yourself, and then finding part of it spoiled a few weeks later.
The good thing about growing food season after season is that eventually you learn that harvesting isn’t always the last step.
For a lot of storage crops, there’s another job between the garden and the pantry: curing or drying. They can sound like two names for basically the same thing, but they’re actually different processes with different purposes.
Curing is what I think of as preparing a living crop for storage. Garlic and onions need time in a dry, well-ventilated place so their outer layers and necks can dry down. Potatoes are handled differently: they’re kept under specific conditions that allow minor harvest damage to heal and the skin to toughen. Sweet potatoes need warm, humid conditions after harvest, which helps wounds heal and improves their storage quality. Winter squash also benefits from curing, although the right conditions and time vary by type.
Drying is different. With dry beans, dry peas, popcorn, sunflower seeds, walnuts, and hazelnuts, the goal is to remove enough moisture from the harvested portion that it can be stored safely. I’ve learned not to rush that step just because something looks dry on the outside.
Peanuts are a bit of their own thing. After digging, they need a curing/drying period so the pods and kernels lose moisture before storage.
And this is where I’ve made mistakes before: treating every crop like it wants the same conditions.
It doesn’t.
Some need warmth. Some need humidity during curing. Others need plenty of airflow and progressively drier conditions. Potatoes even need darkness because light can cause greening.
So these days, when the harvest comes inside, I don’t automatically think, Good, that job is finished.
I think, What does this crop need before I put it away?
Because after spending months growing something, losing it in storage over one skipped step is a lesson I’d rather not learn twice.
