Shipping Information & Notes

Harvest for Seed - It is quite easy to tell when it is time to harvest your sunflowers. The head will have become brown and dry, almost wilted, and most of the yellow leaves will have fallen off. It might be possible to mistake the sunflower as old and dead at this time, but the seeds in the middle will be both fat and juicy, with a black and white striped outer coating. The seeds should look full and be hard to the touch. The heads may be left in the field until dry down is completed, but the birds will often take a heavy toll on them before they are brought in. Another way to harvest them is to cut the heads off the plant leaving about a foot of stem. Hang them in a warm and dry environment and wait for the seeds to dry. You may want to place row covers underneath them to capture any seed that falls off. Check the heads frequently for birds and rodent damage; sunflowers are a favorite food source of mice, rats, and birds. Simply rubbing the seeds with your hand will dislodge the seeds from their heads once they are dry enough.
