Start seeds indoors 6-8 weeks before your last frost date. Keep soil consistently moist at a germination temperature of 65-75°F. Snapdragon seeds benefit from light exposure, so press them gently onto the soil surface rather than covering them deeply. Seedlings will emerge in 7-14 days.
Harden off seedlings by gradually exposing them to outdoor conditions over 7-10 days before transplanting. Plant outdoors after the last frost date when soil has warmed. Space plants 12-18 inches apart to allow for air circulation and their mature width. Defiance reaches 36 inches tall, so provide support or plant in protected locations where wind won't damage the tall stems.
Direct sow seeds outdoors after the last frost date once soil temperatures reach 60°F or warmer. Sow seeds on the soil surface, pressing gently but not covering, as light aids germination. Keep soil consistently moist until seedlings establish.
For cut flowers, harvest snapdragon spikes in the early morning when blooms are fully open along the stem. Cut stems at their base, selecting spikes with many open flowers and unopened buds at the tip for longest vase life. Remove lower leaves that would sit below the waterline in your arrangement.
Pinch back young seedlings when they reach 4-6 inches tall to encourage bushier growth and more flower spikes. Deadhead spent flower spikes regularly throughout the blooming season to promote continuous flowering and extend the display from late spring through fall.
