Check these first

  1. Look for slimy trails on the leaves.
  2. Inspect the underside of the leaves during the evening.
  3. Check the soil surface for hiding pests.

Likely causes

  1. Slugs

    Most likely

    How to tell: You see slimy trails on the leaves or soil and ragged holes in the foliage. They are most active at night or during wet weather.

    What to do: Handpick slugs off the plant in the evening when they are active. You can also set out shallow dishes of beer or use copper tape around the base of the plant to deter them.

  2. Snails

    Possible

    How to tell: Similar damage to slugs but you might find the shells nearby. They leave behind the same telltale slime trails.

    What to do: Remove any debris or mulch near the base of the plant where snails like to hide. Use organic iron phosphate baits if the infestation is severe.

Keep the area around your plants clean of dead leaves and debris to remove hiding spots for slugs and snails.
