How to grow Wave Purple Petunia seeds

Choose Your Planting Method

• Indoors: Start indoors 8–10 weeks before the last frost.
• Outdoors: Direct-sow after the last frost, though indoor starting gives earlier blooms.

Prepare Your Materials

• Seed-starting trays or pots
• Well-draining potting mix
• Humidity dome or plastic cover
• Spray bottle for misting

Sowing the Seeds

• Surface-sow — petunia seed needs light to germinate, so do not cover it.
• Mist well and keep evenly moist.

Provide the Right Conditions

• Light: Bright light from sowing onward.
• Temperature: 72–75°F (22–24°C) for the fastest germination.
• Humidity: Keep the surface evenly moist until seedlings emerge.

Germination

• Germination takes about 5–7 days in ideal warm conditions, and up to 1–3 weeks in typical home settings.
• Grow seedlings on in strong light so they stay compact.

Transplanting

• Set out after all frost danger has passed.
• Space plants 12–24 inches apart to allow for their wide spread.

Care Tips

• Sun: Full sun for the most flowers.
• Water: Water regularly; large plantings in heat need consistent moisture.
• Fertilizer: Feed every 1–2 weeks during the season.
• Trim back lightly mid-season if plants get leggy to refresh blooming.

Bloom Time:

From planting until frost.
