Growing Petunias
Reliable color from spring through frost, especially once the summer heat sets in.
How to Grow Petunias
Planting
Best from a transplant, seed is fine and slow to establish. Give them a spot with good airflow to help with humidity-related disease.
Watering & feeding
Regular watering, especially in containers, which dry out fast in our summer heat.
Harvest
Deadhead and trim back leggy stems through the season to keep blooms coming.
Grows Well With
Plant petunias near tomatoes, they’re said to help deter tomato hornworms and add season-long color at the base of the plants. See all our companion planting pairs →
When to Plant
Set out transplants after last frost, mid-April. Trim back hard in July if they get leggy, and they’ll flush out again for fall. See the full planting calendar →
