Check these first
- Look for slime trails on the leaves or the soil surface.
- Check the undersides of leaves for small pests.
- Observe if the spots appear after you have watered the foliage directly.
Likely causes
Slugs and Snails
Most likelyHow to tell: You will see irregular holes or chewed edges on the leaves, often accompanied by shiny slime trails. They are most active during damp, cool weather.
What to do: Hand pick the pests off the plant in the evening when they are most active. You can also place copper tape around the pot or use an organic slug bait.
Fungal Leaf Spot
PossibleHow to tell: Small brown or black spots appear on the foliage, often with a yellow halo. This is caused by water sitting on the leaves for too long.
What to do: Remove the affected leaves to stop the spread. Water only at the base of the plant to keep the foliage dry. Improve air circulation around the plant to help it dry out faster.

When to worry
Worry if the spots are spreading rapidly and causing the leaves to wilt. Minor cosmetic damage from a single slug is usually not a threat to the plant.
Stopping it coming back
Keep the area around your plant clean of debris and water the soil directly rather than overhead.
