Seed-producing sunflowers (Helianthus annuus) produce bright yellow flowers in the summer. The large central disk of each flower becomes filled with seeds after the plant reaches maturity and the flowers die. Birds and small mammals often raid the drying seed heads before harvest and they can quickly decimate your crop. Protecting the seeds from pests while still allowing them to cure properly on the plant ensures an abundant harvest when you're ready to pick the seed heads.
Monitor the sunflowers daily once they begin to bloom. Seeds begin forming once the petals wilt and begin to fall off.
Poke small holes in a paper bag and place the bag over the top of the sunflower bloom once the petals wilt to protect them from birds. Alternatively, use a cheesecloth bag or a pantyhose leg.
Tie the bag or pantyhose leg closed around the stem with twine so small birds and mammals can't access the seed head from below.
Cut off the sunflower stalk once the seeds finish forming and the back of the flower head turns yellow and dry. Finish drying the seed head inside the bag for two or three weeks by hanging them in a dry, warm, well-venilated location. The bag catches any seeds that drop during drying.
Things You Will Need
- Paper bag, cheesecloth bag or pantyhose
- Slugs can pose a threat to young sunflower seedlings. Set slug traps near the base of the seedlings to protect them if slug damage is a problem. The traps attract the slugs so they don't feed on the tender young plants.
