Snapdragons, scientifically known as Antirrhinum majus, are lovely, multicolored flowers that provide a riot of color to gardens when they bloom in the fall and winter. You can grow them in pots or along a border; they're that simple. To effectively cultivate snapdragons, follow these steps:
Location: Full sun to partial shade; well-draining, slightly acidic soil (pH 6.2–7.0).
Planting: Start seeds indoors 8–10 weeks before the last frost. Transplant outdoors after frost, spacing 6–12 inches apart.
Watering: Keep soil moist but not waterlogged; water at the base to avoid disease.
Fertilizing: Use balanced fertilizer (10-10-10) monthly or slow-release at planting.
Pinching & Deadheading: Pinch back young plants for bushier growth. Deadhead spent flowers to encourage continuous blooms.
Pest Control: Watch for aphids, spider mites, and caterpillars; use neem oil if needed.
Disease Prevention: Ensure good air circulation; avoid overhead watering to prevent mildew.
Seasonal Care: Best in spring and fall; avoid hot summers.
Seed Collection: Let flowers dry on the plant to collect seeds for the next season.
Attracts Pollinators: Snapdragons bring in bees, butterflies, and hummingbirds.
