Seed saving: How to deal with stalks & pods
If you've ever tried to save seed from mustard or brassicas (like kale, brussels, broccoli, etc) you know that you end up with tons of tall stalks with tiny seeds stuck in skinny seedheads. It takes way too long to individually strip all those open - so what's the alternative?
There's two main ways to do it. Get a pillowcase and put the heads of the stalks inside, or lay out a large sheet or drop cloth. Then start hitting!! You can knock the seedheads against the ground, step on them, or pound them between two pieces of wood π₯
Once you've thoroughly beat up your seedheads and vented your anger for the week, you should have a combination of seed and debris, called chaff. Now you need to winnow the seed, AKA separate it from the leftover husks and plant material that might house bugs or inhibit long-term storage π
There's a few ways to winnow seed. If you've got a fan or a nice windy day, you can pour the seed back and forth between two buckets and let the wind carry the chaff away while the heavier seeds fall straight down. You can also run them through a series of screens with smaller and smaller holes. I like to use a cone strainer to shake loose seed from larger debris, then use the wind to clear the rest of the very fine chaff π
You should end up with clean seed that can be replanted in the spring or fall, with far less time and effort than individually stripping the stems. I use a similar method for seeds with large pods like beans and peas, simply putting them in a pillowcase and hitting it around for a while to shake out all the beans to the bottom. Don't smash those larger pods between anything though! π«
Saving seed, especially ones that don't easily cross pollinate to something new like tricky squashes, lets you reproduce the best plants that thrived in your specific area and garden. It gives you more to work with next year and share, lets you experiment with your favorite varities, and is a big step towards community food security. Plus, you get to let loose and thrash around some pillowcases - go have fun and try it out! ππ₯
