🌱 How to Grow Wave Petunia Seeds Successfully

Wave Petunias grow beautifully from seed with the right technique.

---

1. Start Seeds Early Indoors

Begin 10–12 weeks before last frost.

• Surface-sow seeds — Wave Petunias need light

• Mist lightly

• Keep at 70–75°F

• Cover with humidity dome until sprouting

Germination takes 7–14 days.

---

2. Provide Strong Light

After sprouting, seedlings need:

• 14–16 hours of bright light

• A fan for airflow

• Cooler temps (60–65°F)

Strong light prevents stretching and builds sturdy plants.

---

3. Transplant to Larger Pots Early

Wave Petunias grow vigorously. Move them to:

• 3–4” pots

• Quality potting soil

• Light fertilizer every 7–10 days

Early up-potting creates bigger, fuller baskets later.

4. Harden Off & Plant Outdoors

Plant outside after frost danger passes.

Wave Petunias prefer:

• Full sun (6–8+ hours)

• Fertile, well-drained soil

• Neutral to slightly acidic pH

---

5. Feed Regularly for Huge Bloom Power

Wave Petunias require more fertilizer than many annuals.

Use:

• Balanced fertilizer early

• Bloom booster in summer

• Weekly feeding

This ensures nonstop flowering.
