🌱 How to Grow Wave Petunia Seeds from Start to Finish

Wave Petunias can be easily started from seed — saving you money and giving you earlier, stronger plants.

✅ Sowing & Germination

  • Start 10–12 weeks before last frost date.

  • Sow on the surface — do not cover seeds (they need light).

  • Maintain 70–75°F (21–24°C) for best germination.

  • Use fine seedling mix and gentle misting to avoid displacement.

  • Germination takes 5–10 days.

✅ Transplanting & Growth

  • Transplant once seedlings show 2–3 true leaves.

  • Use 200–288-cell trays for strong root development.

  • Keep light bright to prevent stretching.
