Why Snapdragons?

  • Incredible Vase Life: Homegrown snapdragons can last up to two weeks in a vase.

  • Extended Bloom Time: With the right care, snapdragons will keep blooming all season long!

So let’s get planting!

Step 1: Start Your Snapdragons Indoors Now

When to Start Seeds

Snapdragons need 10-12 weeks to grow from seed to transplant size, meaning starting them indoors in late winter or early spring is key. If you wait too long, they won’t have time to establish before warm weather arrives.

Best Seeding Practices

What You’ll Need:

✔️ Snapdragon Seeds (Choose from varieties like ‘Madame Butterfly’ or ‘Potomac’ for stunning blooms)
✔️ Seed-Starting Trays or Small Pots
✔️ High-Quality Seed-Starting Mix (Light, well-draining soil)
✔️ Grow Lights or Bright Windowsill
✔️ Humidity Dome or Plastic Wrap
✔️ Spray Bottle for Misting

How to Plant

  1. Fill seed trays with a fine, well-draining seed-starting mix.
  2. Sprinkle seeds on the surface—they need light to germinate, so don’t bury them!
  3. Mist lightly with water to ensure the soil is damp but not soggy.
  4. Cover trays with a clear plastic lid or plastic wrap to hold in moisture.
  5. Place under grow lights or in a bright window (keep temps between 65-70°F for best germination).
  6. Keep the soil consistently moist but avoid overwatering to prevent damping-off disease.

🌱 Pro Tip: Snapdragon seeds can take 7-14 days to germinate, so be patient!

Step 2: Transplanting & Hardening Off

Once your seedlings develop at least 2-3 sets of true leaves, it’s time to start preparing them for life outdoors.

When to Transplant

  • In mild climates: You can transplant 4-6 weeks before your last frost—snapdragons tolerate light frosts if properly hardened off.
  • In colder climates: Wait until about 2 weeks before your last frost, but start hardening them off earlier.

Hardening Off Process

  1. Take your seedlings outside for 1-2 hours a day, gradually increasing exposure over a week.
  2. Keep them in a sheltered location at first to protect from strong winds and direct sun.
  3. After about 7-10 days, they should be ready to plant directly into your garden or containers.

Pro Tip: Snapdragons thrive in full sun but appreciate some afternoon shade in hotter climates!

Step 3: Caring for Your Snapdragons

Now that your snapdragons are in the ground, here’s how to keep them happy:

Soil & Watering

  • Plant in well-draining soil rich in organic matter.
  • Water deeply 1-2 times a week, ensuring the soil stays moist but not soggy.

Fertilizing

  • Use a balanced flower fertilizer (10-10-10) every 3-4 weeks for strong stems and vibrant blooms.

Encouraging More Blooms

  • Pinch the tips of young plants to encourage branching and more flowers.
  • Deadhead regularly to keep the blooms coming all season.

Pro Tip: If you want fall blooms, cut back snapdragons after summer to encourage a second flush of flowers!

Step 4: Harvesting for Cut Flowers

Snapdragons are one of the best flowers for bouquets and arrangements, thanks to their tall, long-lasting stems.

How to Harvest

  • Cut when the bottom 1-2 blooms are open—they’ll continue blooming after cutting.
  • Use sharp scissors or pruning shears to make a clean cut.
  • Immediately place stems in fresh, cool water to extend vase life.

Pro Tip: Adding a floral preservative or a teaspoon of sugar to the vase water helps keep snapdragons fresh longer!
