How to grow Frost Fire Petunia seeds

Choose Your Planting Method

• Indoors: Start seeds indoors 8-10 weeks before your last frost date, on the surface of moist seed-starting mix.
• Outdoors: Direct sowing outdoors is possible after the last frost in warm soil, but indoor-started transplants give more reliable results.

Prepare Your Materials

• Seed-starting trays or pots (if indoors)
• Well-draining potting mix
• Humidity dome or clear plastic cover
• Spray bottle for misting

Sowing the Seeds

• Sow seeds on the surface and press them gently into the mix — petunia seeds need light to germinate, so do not cover them.
• Keep the surface evenly moist; a humidity dome helps until seedlings emerge.

Provide the Right Conditions

• Light: Bright light once sown — light aids germination.
• Temperature: 72-77°F (22-25°C) until germination, then 60-70°F (16-21°C).
• Humidity: A humidity dome or plastic cover helps keep the surface from drying out before germination.

Germination

• 7-10 days under warm, bright conditions.
• Remove the cover as soon as seedlings appear and give them bright light to keep them stocky.

Transplanting

• Transplant outdoors after all danger of frost has passed, once seedlings have several sets of true leaves.
• Spacing: 10-12 inches apart

Care Tips

• Sun: Full sun.
• Water: Water regularly; allow the soil surface to dry slightly between waterings — petunias are sensitive to overwatering.
• Fertilizer: Feed every 1-2 weeks with a balanced liquid fertilizer for continuous bloom.
• Allow the soil to dry slightly between waterings — petunias are sensitive to overwatering.
• Remove faded blooms to keep new buds coming.

Bloom Time:

Late spring through fall.
