Likely causes
Slugs
Most likelyHow to tell: You will see irregular holes or chewed spots on the young leaves. Look for shiny slime trails on the soil or nearby leaves.
What to do: Pick the slugs off by hand in the evening or early morning. You can also place a shallow dish of beer near the base of the plant to trap them.
Fungal leaf spot
PossibleHow to tell: Small brown or black spots appear on the leaves, sometimes with a yellow halo. This often happens if the leaves stay wet for too long.
What to do: Remove the affected leaves to stop the spread. Ensure the plant has good air circulation by not crowding it with other plants.

When to worry
Small, occasional holes are normal in a garden setting. Worry if the damage is widespread or if the plant stops producing new growth.
Stopping it coming back
Water at the base of the plant rather than overhead to keep the foliage dry, and keep the area around the plant clear of debris.
