- Ensure the plant has enough space for air to move around it.
Likely causes
Aphids
PossibleHow to tell: You will see tiny green or black insects on the new growth or undersides of leaves. They leave behind sticky residue that can cause discolored spots.
What to do: Wipe the leaves with a damp cloth or use a gentle stream of water to wash the insects off. For persistent cases, apply insecticidal soap according to the label instructions.
Fungal Infection
PossibleHow to tell: Small, dark, or water soaked spots appear on the leaves, often spreading if the plant stays wet. This is usually caused by poor air circulation or moisture on the leaves.
What to do: Remove the affected leaves to stop the spread. Improve air circulation around the plant and avoid getting water on the foliage when you water the soil.

When to worry
Worry if the spots are spreading rapidly or if the leaves are turning yellow and falling off. Small, isolated spots can often be managed by removing the damaged leaf.
Stopping it coming back
Keep the leaves dry when watering and ensure the plant is in a well ventilated area.

Questions people ask
- Can I use neem oil for the spots?
- Yes, neem oil is effective against both aphids and some fungal issues. Apply it in the evening to avoid burning the leaves in the sun.
- Should I isolate my plant?
- Yes, if you see insects or spreading spots, move the plant away from others. This prevents any potential pests or fungi from jumping to your other plants.
