Hi. I am new here and new to saving seeds. I was not able to cut my broccoli to eat and it went to flower while on vacation. After I pulled it out of the ground I noticed it was covered with small green seed pods. Can I hang it to dry, in the garage or shed I guess, to get seeds? how will I know if I pulled it too early to get good seeds? just Trial and Error?
PS- I am in the process of harvesting radish seeds. though I waited for the pods to dry, a few were still somewhat green. Can I dry the individual seeds on a paper towel? any specific time? or just till just till they turn brown?

Thanks
