Take one kale plant, overwinter it in hoop house – kale is a biennial. In Spring let it flower and go to seed.
Cut it down when leaves start getting brown, hang upside down to dry for months.
When plant is fully dry and pods are almost bursting, stick the entire plant into a pillowcase. Whack.
Take a peek.
Using a strainer, separate seeds from the chaff – which smells wonderful.
Marvel at the thousands of seeds from just one plant. Store for sowing in a few months and distributing among friends.
Russian Kale seeds. Who wants some?
