Start seeds indoors 6 to 8 weeks before your last spring frost. Sow seeds on the soil surface or barely press them into the medium, as snapdragons require light to germinate. Keep the soil temperature between 65 and 75°F for best germination. Seedlings will be ready to transplant outdoors after the last frost date in zone 4.
Transplant hardened-off seedlings outdoors after your last spring frost in zone 4. Space plants 6 inches apart in full sun locations. Choose a spot with well-draining soil at pH 6.0 to 7.0. Water gently after planting to settle the soil.
Direct sow seeds outdoors after the last frost date in zone 4. Sow directly on prepared soil and barely press seeds into the surface. Keep the soil evenly moist until seedlings establish. Thin seedlings to 6 inches apart once they develop true leaves.
Harvest snapdragon flowers for cutting when the lower florets on the spike are fully open but the upper buds remain tight; this allows the arrangement to continue opening and last longer in the vase. Cut stems in the early morning or evening when they are most turgid. Use sharp scissors or pruners to make clean cuts, and bring them indoors immediately to water.
Pinch out the growing tips of young plants when they reach 4 to 6 inches tall to encourage branching and a bushier, more robust plant with more flower spikes. Deadhead spent flowers regularly throughout the season to extend blooming and promote continued flower production through fall.
