Hi Andy, First, you can leave sunflower heads on the plant as the seeds start to try. When the top of the blossom separates from the seed (or, the birds start eating the seeds), cut the head and finish curing the seed in a warm, ventilated area. Once the seeds are dry, store in an envelope or container in a cool, dry place where they are protected from insects.
