How to grow Superissima Triumph Mix Petunia seeds

Choose Your Planting Method

• Indoors: Start seeds indoors 8-10 weeks before the last frost date.
• Outdoors: Sow outdoors only after all danger of frost, when nights are warm.

Prepare Your Materials

• Seed-starting trays or pots (if indoors)
• Well-draining potting mix
• Spray bottle for misting

Sowing the Seeds

• Sow on the surface of fine seed-starting mix and press gently; cover with only a thin dusting of vermiculite, as light aids germination.
• Mist and cover with a humidity dome or plastic wrap to hold moisture.

Provide the Right Conditions

• Light: Bright light; seedlings grow best under strong, indirect light.
• Temperature: 72-77°F (22-25°C) for germination.

Germination

• Seeds typically germinate in 6-10 days.
• Remove the cover once seedlings emerge and grow them on in bright light.

Transplanting

• Transplant after all danger of frost, once nights stay above 50°F (10°C).
• Harden off for 7-10 days before planting out.
• Space plants 12-24 inches apart, depending on bed density.

Care Tips

• Sun: Full sun for the heaviest bloom.
• Water: Water regularly; let the top inch of soil dry between waterings.
• Fertilizer: Feed every 2-3 weeks with a balanced liquid fertilizer.
• Pinch or remove spent flowers to encourage more blooms; shear back leggy plants in midsummer for a fresh flush.

Bloom Time:

Summer through fall, until frost.
