Common Marigold 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.
