How to propagate Snapdragon
Seed
- Surface-sow the tiny seeds and press in lightly; they need light.
- Keep cool (around 65F) and moist until germination.
- Pot on seedlings once they have a few true leaves.
- Harden off and plant out; they tolerate light frost.
Softwood cuttings
- Take a 3-inch non-flowering tip cutting below a node.
- Strip the lower leaves and dip the base in rooting hormone.
- Insert into moist cutting mix and keep lightly humid.
- Pot on once rooted.
Common Snapdragon 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 â 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.
