Growing Basics
Snapdragons are cool-season annuals in Minnesota. They thrive in spring and fall, and may slow down or stop blooming during the hottest stretch of summer.
Sunlight: Full sun (6+ hours daily).
Soil: Rich, well-drained soil.
Transplanting: Snapdragons can handle light frost, so you can plant them out a bit earlier than most annuals â a week or two before your last frost date is fine. Plant at the same depth as in the pot.
Watering: Keep soil evenly moist. Water at the base of the plant to help prevent fungal issues.
Fertilization: Fertilize every 4â6 weeks with a balanced fertilizer (10-10-10).
Other Tips
Deadhead spent flower spikes to encourage new blooms.
Tall varieties (18â36") may need staking, especially in windy spots.
If blooming slows in July heat, cut plants back by about a third. When cooler weather returns in late summer, they'll often rebound with a second flush of flowers before frost.
Great for cutting â the flower spikes last well in a vase.
