when do you harvest the sunflower seeds off the plant? They are in my garden and kissing the gound.?

1. Usually this happens because the weight of the seeds is too much for the plant to bear. I would suggest harvesting the seeds as soon as possible.
2. Harvest begins in mid-September and can run into October. A check of the flower head will indicate maturity; florets in the center of the flower disk are shriveled, heads are downturned, and a lemon yellow color is on the backside. Pull a few seeds and split them with a knife to check if seed meat has filled. Poorly filled seeds may be due to a lack of pollinating insects. To harvest, cut the seed head with about a foot of stem attached and hang in a warm, dry, well-ventilated, rodent and insect-free place. A paper bag with holes or cheesecloth can be placed over the heads to catch falling seeds as they drop during drying. Seed heads can be allowed to ripen on the plant, but cheesecloth or nylon netting will be needed for bird protection. Once the seed is dried, it can be rubbed easily from seed heads. Humidity levels must be kept low to prevent spoilage.
