Harvesting bok choy and choy sum seeds?
I started growing Asian greens some months ago and left a few to become mother plants. Now both my bok choy and choy sum are carrying numerous seed pods but I don't know when I should harvest the seeds in the pods. The pods have been on the plants for several weeks now and don't seem to be getting any bigger. However they are still green. I cut a few off to dry in the sun. When I cracked them open, some of the seeds are still green. Does this mean they're not yet fully developed? Should I leave the pods on the plant until it starts to turn brown?
