Planting Details
| Seed Depth | 1/2" |
|---|---|
| Seed Spacing | A group of 2 seeds every 18" ‒ 24" |
| Thinning | When 3" tall, thin to 1 every 18" ‒ 24" |
| Germination | 10 – 15 Days |
| Start Indoors | 2 to 4 weeks before your average last frost date. Sunflowers are sensitive to root disturbance; sow in biodegradable pots that can be planted directly in the ground. |
| Direct Sow | RECOMMENDED. 1 to 2 weeks after your average last frost date. |
| Special Care | Avoid overhead watering to prevent disease. If grown in less than 8 hours of sun, you may have to stake the sunflowers by placing the stake in the ground at sowing time to avoid root damage. Deadhead (remove spent blossoms) regularly unless you are growing them to harvest the seeds. For long stems, sow tighter spacing of 10"; flowers will be smaller than those grown in a wider spacing. |
