Planting Details
| Seed Depth | 1/8" |
|---|---|
| Seed Spacing | A group of 3 seeds every 4"-6" |
| Thinning | When 1/2"-1" tall, thin to 1 every 4"-6" |
| Germination | 7-20 days |
| Start Indoors | 8 to 10 weeks before your average last frost date for early spring planting, and midsummer for fall planting in both mild and cold climates. |
| Direct Sow | RECOMMENDED. Cold Climates: 4 to 6 weeks before your average last frost date, or midsummer for fall and the following spring bloom. Mild Climates: Late summer for cool-season blooms. |
| Special Sowing | Darkness aids germination; sow at recommended depth. |
| Special Care | If grown under optimum conditions, and regular attention given to proper deadheading and pruning, violas will last year after year. Pinch off faded flowers to the bottom of their stems to encourage more blooms and prevent reseeding. In all climates, when the weather warms up in summer, plants tend to get ragged, stretched out, and slow to bloom. Trim back the flower stalks to promote new foliage and encourage fall bloom. |
| Growing & Harvesting | For longest vase life, harvest flowers in the morning, choosing stems where flower buds have just begun to open. Change vase water frequently. |
