Growing & Seed Saving Tips

From Adaptive Seeds:

“Sow in pots indoors February through May or August through September. Transplant 3-4 weeks after sprouting. May also be direct sown in early spring or late summer. Hot weather may cause premature bolting and/ or extra spicy flavor. Succession sow to extend harvest. Flowers are edible.

Seed Saving

Collect seeds from overwintered or early spring sown plants, selecting for slowest bolting. Cut seed heads when pods are dry, thresh by hand or by dancing, winnow to clean. Isolate from other Brassicas of the same species by ½ mile.”
