- Eventually the blooms will fall off and then a pod will form and grow to about 2 or 3 inches long. This pod will swell. I've harvested all of my radish seed starting when the topmost pods are brown and starting to dry out. I just cut the stalks to ground and removed all the pods. Put the pods in a flat and in the Sun until they're dry. The pods break easily between your fingers and the little seeds fall loose. Then I winnow the pod pieces out in the wind. I've collected about 1/4 cup of Giant radish seed already and I still have two flats to go! Winnow means to pour the seed and chaff from one container to another in a stiff breeze (not a gale!) until a satisfactory amount of chaff has been blown out of the seed. You will loose some of the seed this way, but it beats the heck out of removing the chaff piece by piece!
