When to worry
If the plant is losing more than half of its foliage, it may struggle to recover. Small amounts of damage are usually just a nuisance.
Stopping it coming back
Keep the area around your plant clear of debris where slugs hide. Water in the morning so the soil surface dries out by evening.
