2. Sowing Petunia Seeds in February

Petunia seeds are tiny and require careful handling, but starting them indoors in February ensures strong, healthy plants.

2.1 Preparing for Sowing

Use seed trays or shallow pots filled with a fine, well-draining seed compost.
Lightly moisten the compost before sowing.

2.2 How to Sow Petunia Seeds

Sprinkle the tiny seeds on the surface of the compost without covering them, as they need light to germinate.
Cover the trays with a clear lid or plastic wrap to retain humidity.
Place the trays in a bright location with a temperature of 70–75°F (21–24°C).

2.3 Germination

Petunia seeds typically germinate within 7–14 days. Keep the soil consistently moist but not waterlogged.

3. Transplanting and Planting Petunias

3.1 Pricking Out Seedlings

When seedlings develop their first true leaves, carefully transplant them into individual pots to encourage root growth.

3.2 Hardening Off

Gradually acclimate seedlings to outdoor conditions by placing them outside during the day for 7–10 days before planting out.

3.3 Planting Out

Plant petunias outdoors in late spring after the last frost.
Space plants 8–12 inches apart for compact varieties and 12–24 inches for trailing types.

4. Caring for Petunias

4.1 Watering

Water regularly, keeping the soil evenly moist but not soggy.
Avoid overhead watering to prevent damage to delicate flowers.

4.2 Feeding

Feed petunias every 2–3 weeks with a balanced liquid fertilizer during the growing season.
For more blooms, use a fertilizer high in phosphorus.

4.3 Deadheading

Remove spent flowers to encourage continuous blooming and prevent seed formation.

4.4 Pruning

Trim back leggy stems to promote bushier growth and more flowers.

5. Protecting Petunias from Pests and Diseases
