Producer: Riya Ashok
Look for fresh seeds, and check the expiration date on the seed packet.
Start seeds indoors 8-10 weeks before the last expected frost date in your area.
Place the seed trays or pots in a bright location or provide artificial light with a fluorescent grow light.
Plant petunia seeds in a well-draining seed-starting mix.
Before sowing the seeds, moisten the soil in the seed trays or pots. Water the soil thoroughly and allow it to drain before planting the seeds.
Gently press the petunia seeds onto the soil surface, but don't cover them with soil.
Water the seedlings from the bottom to prevent damping off, a fungal disease that affects seedlings.
