How to propagate Petunia

Softwood cuttings

Difficulty: EasyTimeline: Roots in 2-3 weeks; pot on once rooted.
  1. Take a 3-4 inch non-flowering tip cutting below a node.
  2. Strip the lower leaves and pinch off any buds.
  3. Dip the base in rooting hormone and insert into moist cutting mix.
  4. Cover loosely to hold humidity and keep bright.
  5. Pot on once rooted.

Seed

Difficulty: ModerateTimeline: Germinates in 1-2 weeks; transplant out after the last frost.
  1. Surface-sow the tiny seeds and press in lightly; they need light.
  2. Keep warm and moist until germination.
  3. Pot on seedlings once they have a few true leaves.
  4. Harden off and plant out after all danger of frost.

Common Petunia problems & fixes

Cuttings rot before they root

Too wet or no airflow. Use a free-draining mix, water sparingly, and vent the humidity cover daily.

Cuttings wilt after taking them

Normal at first — keep humidity high under a dome, out of direct sun, until roots form and perk them up.

Powdery mildew on leaves

Poor airflow and damp foliage. Space plants out, water at the base, and improve circulation.
