Check these first
- Inspect the undersides of the leaves for pests.
- Check if the leaves stay wet for too long after watering.
- Look for orange dust on your fingers when touching the spots.
Likely causes
Fungal Rust
Most likelyHow to tell: Small orange or brown spots appear on the leaves, often looking like dust.
What to do: Remove the affected leaves immediately to stop the spread. Improve air circulation around the plant by moving it to a more open space.
Water Splashing
PossibleHow to tell: Small brown spots appear after you water the plant from above.
What to do: Water the soil directly at the base of the plant rather than pouring water over the foliage. This keeps the leaves dry and prevents fungal growth.

When to worry
If the spots cover most of the foliage, the plant is struggling to photosynthesize. Small, isolated spots are manageable with pruning.
Stopping it coming back
Ensure good airflow around your plant and always water at the soil level to keep leaves dry.
