- Check if the leaves are staying wet after watering.
- Look for slime trails on the soil surface.
Likely causes
Slug damage
Most likelyHow to tell: You will see irregular holes or chewed edges on the tender spring foliage. Slugs often leave a faint slime trail behind.
What to do: Handpick slugs off the plant in the evening or early morning. You can also place a shallow dish of beer near the base to trap them.
Fungal leaf spot
PossibleHow to tell: Small brown or black spots appear on the leaves, often with a yellow halo. This happens when the foliage stays wet for too long.
What to do: Remove the affected leaves to stop the spread. Water the soil directly at the base rather than splashing the leaves.

When to worry
If the spots are spreading quickly and covering most of the foliage, the plant is struggling. A few small spots are usually just cosmetic and not a major threat.
Stopping it coming back
Keep the area around your plant clean of debris where slugs hide. Ensure good air circulation to help leaves dry quickly.
