Seed Germination
1-2 weeksTiny seeds germinate in 7-14 days at 65-75°F. Seedlings emerge as delicate two-lobed cotyledons.
Keep soil moist but not waterlogged. Provide bright, indirect light. Avoid burying seeds; they need light exposure.
Seedling
2-3 weeksFirst true leaves appear, followed by development of a small bushy plant with 4-6 leaves.
Maintain consistent moisture and warm temperatures (65-70°F). Begin fertilizing weakly with balanced fertilizer every 2 weeks.
Vegetative Growth
3-4 weeksPlant develops a compact, bushy habit with multiple stems and increasingly dense foliage, reaching 4-6 inches tall.
Pinch back growing tips when 3-4 inches tall to encourage bushiness and more flower spikes. Transplant to garden when frost danger passes.
Flowering
6-12+ weeks (until frost or heat stress)Flower spikes emerge from leaf axils with densely packed snapdragon blooms in various colors.
Deadhead spent flowers regularly to promote continuous blooming. Water consistently and fertilize every 2-3 weeks with balanced or slightly higher phosphorus fertilizer.
End of Season
Varies by climateBlooming slows in high heat (above 85°F) or after first frost; plants may be discarded or cut back to regrow in fall.
In cool climates, snapdragons may rebloom if cut back and watered well as heat subsides. In warm zones, stop growing in summer heat and restart in fall.
