Snapdragon - Key Growing Information
DAYS TO GERMINATION: 7-14 days at 70-75°F (21-24°C)
SOWING: Transplant (recommended) - Surface-sow into open, or 20-row flat or preferred seedling container, 8-10 weeks before last frost. Light is required for germination; cover just enough to hold seeds in place. Transplant into 72-cell plug flats at first true-leaf stage. Harden off and transplant out after danger of frost has passed. 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 cell packs or larger containers when the first true leaves appear, approximately 3-4 weeks after sowing. If desired, for a bushier plant that produces more flower-producing side branches, pinch young plants back by half their height when plants have formed 4-6 leaves or are approximately 3-4 inches tall. Pinching will delay the crop time by a few weeks. If pinching, space plants 6-12 inches apart. Direct seeding is not recommended.
