Planting Details
| Seed Depth | 1/4" |
|---|---|
| Seed Spacing | A group of 3 seeds every 8" – 10" |
| Thinning | When 1" – 2" tall, thin to 1 every 8" – 10" |
| Germination | 14 – 20 Days |
| Start Indoors | 4 to 6 weeks before your average last frost date. Not recommended; does not transplant well. Use biodegradable pots to avoid root disturbance. |
| Direct Sow | RECOMMENDED. 1 to 2 weeks before your average last frost date, or in late summer/fall for blooms the following season. Mild Climates: Sow in fall for winter bloom. |
| Special Care | May require staking, especially if plants are not getting enough sun. Plants may get mildew in part shade; full sun and proper spacing will hinder mildew. To extend bloom season, increase size of existing flowers, and prevent reseeding, remove spent flowers. Successive sowings will provide a more continuous bloom period. |
