Likely causes
Fungal Leaf Spot
PossibleHow to tell: You will see small brown or black circles with yellow halos on the foliage. These spots often spread if the plant stays wet for too long.
What to do: Remove the affected leaves immediately to stop the spread. Improve airflow around the plant and avoid getting water on the leaves when you irrigate.
Spider Mites
PossibleHow to tell: Tiny yellow or white stippling marks appear across the leaf surface. You might notice fine webbing between the stems.
What to do: Wipe the leaves down with a damp cloth to remove the mites. Spray the plant with neem oil once a week for 3 weeks until the pests are gone.

Questions people ask
- Should I cut off all leaves with spots?
- Yes, it is best to remove them to prevent the fungus from spreading to healthy parts of the plant. Use clean scissors and discard the clippings in the trash.
- Can I mist my Copperleaf to prevent spots?
