🌱 How to Grow Petunia Seeds Successfully

Petunias are easy once you understand their early needs.

1. Start Indoors 8–12 Weeks Before Frost

They need light to germinate, so do not cover seeds.

2. Use Consistent Bottom Heat (70–75°F)

This ensures fast, even germination.

3. Provide Bright Light Immediately

Petunia seedlings stretch quickly—use grow lights placed close to the tray.

4. Transplant When Roots Fill the Cell

A 4–6 week-old seedling is perfect for pots and baskets.

5. Feed weekly

Use a balanced liquid fertilizer for strong growth.

6. Pinch once for fuller plants

Just remove the top set of leaves to increase branching.
