How to identify it

  1. Confirm the likely cause before treating.
  2. Remove infected leaves
  3. Remove badly affected leaves or pests where needed.
  4. Improve light, airflow, soil moisture, or spacing.
  5. Track recovery through new growth rather than damaged old leaves.

Prevention

  • Use clean tools and healthy soil.

Common questions

Should I remove damaged leaves?

Remove leaves that are badly diseased, pest-covered, or blocking airflow. Keep mildly damaged leaves if the plant still needs them for growth.

How fast will the plant recover?

Typical recovery is 1-3 weeks, but damaged leaves may not turn green again. Look for healthy new growth.
