🌱 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.
