Sunflowers are one of the most cheerful plants to grow—bright, tall, and loved by pollinators. But once those golden petals fade, it’s time to think about harvesting. Whether you’re after seeds for snacking, replanting, or feeding birds, timing is key.
When to Harvest
Sunflower heads are ready when the back of the flower turns yellow-brown and the petals have dried up. The seeds should look plump and striped (depending on the variety). If birds or squirrels are helping themselves early, you can cover the heads with a paper bag or mesh to protect them.
How to Harvest
Cut the head off the stalk with a few inches of stem still attached. Hang it upside down in a dry, well-ventilated spot until fully cured. Once dry, rub the seeds out with your hand or a stiff brush.
Storing Your Seeds
Keep seeds in an airtight container in a cool, dry place. For eating, roast them lightly with a bit of salt. For planting, save only the biggest, healthiest seeds.
Harvesting sunflowers is a satisfying way to enjoy the full cycle of this sunny plant—from seed to bloom, and back to seed again.
