Care and Maintenance
Watering: It's important to water regularly when they're just starting out; after they’re established, they can handle dry spells.
Fertilization: Before planting, mix in some compost or organic fertilizer since they really like to feed.
Support: If you have taller plants, you might need to stake them for support, especially if it's windy.
Harvesting Seeds
To collect seeds, just cover the flower heads with a paper bag as they dry to keep the birds away. When the heads turn brown, take them inside to dry some more. Keep the seeds in a cool, dark spot for later use.
Mongolian Giant sunflowers are a fantastic addition to any garden, adding beauty and providing seeds for snacking or feeding birds.
