Antirrhinum Mix

🔍 About Antirrhinum Mix

• Type: Tender perennial, grown as annual

• Height: 6 inches to 3 feet (15 cm to 1 m), depending on variety

• Bloom Time: Spring to fall (best in cool weather)

• Light: Full sun to partial shade

• Zones: Hardy to USDA zone 7 (may overwinter with protection)

📅 1. When to Sow

• Indoors: 10–12 weeks before last frost (recommended)

• Outdoors: Direct sow after last frost (less common due to slow germination)

🌱 2. Starting Seeds Indoors

• Containers: Use seed trays or small pots

• Soil: Fine, well-draining seed-starting mix

• Sowing Depth: Do not cover — snapdragon seeds need light to germinate

• Spacing: Sow thinly; transplant later

• Water: Mist gently or bottom-water to avoid washing away tiny seeds

🌡️ 3. Germination Conditions

• Temperature: 65–70°F (18–21°C)

• Light: Required — use grow lights or bright window

• Time: 7–14 days

Tip: Snapdragon seeds can benefit from pre-chilling for 3–5 days in the fridge before sowing for better germination, especially if sown early.

🌿 4. After Germination

• Remove humidity dome or plastic cover

• Provide 12–14 hours of light daily

• Water when top of soil dries out

• Thin seedlings or transplant when they have 2–3 sets of true leaves

🌼 5. Transplanting Outdoors

• Timing: After hardening off, when risk of frost is low

• Spacing: 6–12 inches apart, depending on mature size

• Site: Full sun, well-draining soil, sheltered from strong wind

• Soil: Fertile, neutral to slightly acidic

📌 Tips for Success

• Pinch back young plants to encourage bushy growth

• Deadhead regularly to keep blooms coming

• Can be overwintered in mild climates or treated as biennials

• Great for pollinators and long-lasting cut flowers
