Sunflower Seeds,
Carousel

Sow seeds directly outdoors in late spring after the last frost, when the soil has warmed. If starting indoors, sow seeds 2-3 weeks before the last frost and transplant them once the seedlings are hardened off. Timing is key, so be sure to check local frost dates. If you’re not sure how to find your first and last frost dates, consult our blog post 'Our Experts Answer Questions, Share Resources.'

Plant seeds about 1/2 inch deep, with each plant spaced about 16 inches apart. If growing in containers, make sure that the pots are deep enough for root growth. Keep the soil evenly moist until the seeds germinate, which usually happens in 7-14 days​.

Once the plants are established, they require moderate watering. Carousel sunflowers begin blooming in mid-summer and continue through the fall. While staking isn’t always necessary, providing support may help in windy areas, as the plants can reach up to 4 feet tall​.

• When petals die back and heads begin to dry and turn brown, place a paper bag over the heads to protect seeds from birds.
• After a few days, the heads will dry to a dark brown. Bring the heads indoors and hang them upside down in a dry area in direct sunlight for up to a week, shaking seeds free each day.
• Store seeds in a cool, dark, dry place.
