Snapdragon - Key Growing Information

Planting of the 'Potomac Mix' in our snapdragon trials, which included all four subgroups.
DAYS TO GERMINATION: 7-14 days at 70-75°F (21-24°C)

SOWING: Transplant (recommended) - Sow 8-10 weeks before last frost. Pinching encourages branching. Light is required for germination, but a fine layer of vermiculite covering the seeds can maintain moisture levels and prevent algae growth. Bottom water or mist lightly to avoid covering the seed with displaced soil. Transplant to packs or larger containers when the first true leaves appear, approximately 3-4 weeks after sowing. If desired, pinch back to 1 1/2-2" when the seedlings are about 3-4" tall to encourage branching. Direct seeding is not recommended.
