🌱 How to Grow Wave Petunia Seeds for Big, Full Baskets

Wave Petunias grow easily from seed when started early.

---

1. Start Indoors 10–12 Weeks Before Last Frost

For best results:

• Use a seed-starting mix

• Surface-sow seeds (petunia seeds need light)

• Mist lightly

• Keep soil at 70–75°F

Germination takes 10–20 days.

---

2. Provide Strong Light After Germination

Wave Petunia seedlings require:

• 14–16 hours of light daily

• Cool temperatures (60–65°F)

• Good airflow

• Consistent moisture

This prevents stretching and builds thick, strong plants.

---

3. Transplant to Larger Pots Early

Once seedlings have 2–3 true leaves:

• Pot into 3–4" pots

• Fertilize lightly

• Keep them cool to maintain compact growth

---

4. Harden Off & Plant Outdoors in Cool Weather

Wave Petunias prefer:

• Full sun

• Well-drained soil

• Cool nights (they thrive in spring)

They can be planted outside as soon as frost danger passes.

---

5. Feed Regularly for Maximum Flower Power

Wave Petunias are heavy feeders.

• Apply water-soluble fertilizer every 7–10 days

• Choose a bloom booster during midsummer

• Keep soil evenly moist

Regular feeding = nonstop blooms.

---

🌈 Where Wave Petunias Look Best

Wave Petunias are extremely versatile. They work well in:

• 12–20” hanging baskets

• Patio pots & porch planters

• Window boxes

• Landscape borders

• Mass plantings

• Commercial displays

Their ability to spill over the edges makes them one of the most popular annual flowers in North America.
