When to plant green seeds?

I let these black spanish radishes bolt. When are these green seeds ready to sow? Aside from winnowing, do they need any processing? Must seeds be dried before planting?

I feel silly even asking these questions, as obviously the seeds will eventually dry, fall and self-sow. But now is the time to plant black radishes around here, and I doubt they'll do their own thing in time.

They need to turn brown and dry before they are mature.  Once crunchy, they can be broken from the pod and sewn.

By the way, these green pods are quite tasty and edible, if you don't want to save them all for seed.

Thanks Tyler. I wonder whether my bolted kales will have viable seed then. They grew 6' tall, started to collapse and break their bases before drying...so I let the pods mature as long as possible, then cut and sun-dried them. Does sun-drying, indirect heat drying, or dehydrator protect the germ best?

I thought they might be edible, but haven't yet tried one. Grew rattail radishes a few years ago and those pods were tasty.

My experience is that seeds are viable much sooner than I would have imagined, and that they don't have to dry down before planting. That doesn't mean they are fully mature, just that they can germinate long before full maturity.

You could test them now... Open a pod, take the seeds out, and plant them in a pot. They are radishes. If they are going to germinate, they will do it in a few days. We'd love a grow report.

If you are dealing with green immature seeds, you'll need to be much more careful with harvest than when dealing with dry mature seeds. For example you might want to skip winnowing.

Seeds loose viability quicker at higher temperatures, so I prefer to dry seeds out of direct sunlight.
