Growing Snapdragons adds vibrant color to your garden with their tall spikes of blooms in various shades.
Snapdragons. Sounds like something straight out of a fairy tale, but trust me, they’re real, and they’re stunning. These vibrant blooms are the life of the garden, standing tall with their tubular flowers that look like little dragons ready to take flight. They come in every color under the sun, from bold reds to soft pastels, making them perfect for adding a splash of personality to any flower bed.
They thrive in the cooler months, spring and fall being their sweet spots, and will bloom their hearts out if you give them a bit of love. They’re not the fussiest, but like any diva, they appreciate well-drained soil and a decent amount of sunlight. Just don’t expect them to hang out in too much heat—they tend to sulk when it gets too hot, going dormant until the weather cools down.
And, don’t be fooled by their delicate look. Snapdragons are surprisingly hardy, standing tall against the elements if you treat them right. A little deadheading now and then to keep them looking fresh, and they’ll reward you with blooms that’ll steal the show. Oh, and they’re fantastic for attracting pollinators, so you’ll get a nice visit from some buzzing friends while you enjoy the view.
How to Grow Snapdragons

Growing snapdragons is a fun gardening experience, as these vibrant, long-blooming flowers are relatively easy to cultivate and add a pop of color to any garden.
Planting Snapdragons
- Timing:
- Start Indoors: If you live in a cooler climate, start snapdragons indoors about 8-10 weeks before the last expected frost.
- Direct Sowing: In warmer climates, snapdragons can be sown directly in the garden after the last frost date.
- Location:
- Sunlight: Choose a location that gets full sun to partial shade. Snapdragons thrive in cooler temperatures and appreciate some afternoon shade in hot climates.
- Soil: Well-draining soil is crucial. They prefer soil that is slightly acidic to neutral (pH 6.0-7.0).
- Planting:
- Spacing: Space snapdragon plants about 6-12 inches apart, depending on the variety. This spacing allows air circulation, which helps prevent disease.
- Depth: Plant seeds or transplants just below the soil surface. For seeds, lightly press them into the soil and cover with a thin layer of soil.
Growing Snapdragons
- Watering:
- Regular Watering: Keep the soil consistently moist, but not waterlogged. Water at the base of the plants to prevent wetting the foliage, which can lead to disease.
- Fertilization:
- Balanced Fertilizer: Feed snapdragons with a balanced, water-soluble fertilizer every 4-6 weeks. Avoid excessive nitrogen, which can result in more foliage and fewer flowers.
- Pinching and Deadheading:
- Pinching: Pinch back the tips of young plants to encourage bushier growth and more blooms.
- Deadheading: Remove spent flowers to encourage continuous blooming throughout the season.
Caring for Snapdragons
- Support:
- Taller varieties may need staking or support to prevent them from falling over, especially in windy conditions.
- Pests and Diseases:
- Common Pests: Watch out for aphids, spider mites, and caterpillars. Treat infestations promptly with insecticidal soap or neem oil.
- Diseases: Snapdragons are prone to fungal diseases like rust and mildew. Ensure good air circulation, avoid overhead watering, and remove any affected leaves.
- Seasonal Care:
- Cool Weather: Snapdragons prefer cooler weather and often bloom in spring and fall. In hotter climates, they may struggle during the peak of summer but can rebound when temperatures cool down.
- Overwintering:
- In mild climates, snapdragons can be treated as short-lived perennials and may survive the winter with some protection. In colder areas, they are usually grown as annuals, but you can collect seeds for planting the following year.
Snapdragons Growing Zone
Snapdragons (Antirrhinum majus) are versatile and can be grown in a variety of climates. They thrive best in USDA hardiness zones 7 through 10.
In these zones, they are often grown as perennials, but in cooler climates (zones 5 and 6), they can be treated as annuals or short-lived perennials, particularly if they’re given some winter protection.
Growing Snapdragons FAQ
Snapdragons can be planted in early spring or fall, depending on your climate. In cooler climates, plant in early spring, while in milder areas, they can be planted in the fall for winter blooms.
Snapdragons thrive in full sun but can tolerate partial shade. They prefer well-drained soil enriched with organic matter.
Water Snapdragons regularly to keep the soil evenly moist, especially during dry periods. However, avoid waterlogging, as it can lead to root rot.
Regular deadheading (removing spent flowers) encourages continuous blooming. You can also pinch back the stems to promote bushier growth.
Snapdragons are best grown outdoors, but you can start them indoors from seed 6-8 weeks before the last frost date. Transplant them outdoors once the danger of frost has passed.
Snapdragons typically bloom from late spring to early fall. In cooler climates, they may stop blooming during the hottest part of summer and resume as temperatures cool.
In mild climates (USDA zones 7-10), Snapdragons can act as short-lived perennials and may bloom again the following year. In colder regions, they are usually grown as annuals.
Snapdragons generally prefer full sun but can tolerate partial shade.
