when do you trim the pods on poppy
Wait until the poppy flowers wither and the plant forms a seed pod, which can range from 1/2 inch to 2 inches in diameter. Cut off the seed pod using small pruning shears once it turns a light brown color. Place the poppy seed pods, sometimes called seed heads, in a warm room with low humidity. Spread them on newspaper or paper towels, then let them dry for one to two weeks. The seeds are dry once you hear them rattle inside a pod when you shake it.
