Fern plants are a beautiful addition to any garden or indoor space. Their lush green leaves and delicate fronds add a touch of natural elegance to any environment. However, fern plants are also susceptible to slug infestations, which can damage and even kill the plant. In this article, we will discuss how to get rid of slugs on fern plants.

Signs of Slug Infestation

Before we discuss how to get rid of slugs, it’s important to know the signs of a slug infestation. The most obvious sign is the presence of holes in the leaves of your fern plant. You may also notice slime trails on the leaves or soil around the plant. If you suspect a slug infestation, inspect your fern plant at night when slugs are most active.

Prevention

Preventing a slug infestation is always easier than getting rid of one. Here are some preventative measures you can take:

  • Water your fern plant in the morning to allow the leaves to dry during the day.
  • Keep your fern plant in a well-lit area as slugs prefer dark, damp environments.
  • Avoid over-fertilizing your fern plant as this can attract slugs.
  • Remove any fallen leaves or debris from around the base of your fern plant.

Natural Remedies

If you already have a slug infestation on your fern plant, there are several natural remedies you can try:

Beer Traps

Slugs are attracted to the smell of beer, so placing a shallow dish filled with beer near your fern plant will attract slugs and they will drown in the liquid.

Eggshells

Crushed eggshells scattered around your fern plant can create a barrier that slugs won’t cross as they find it uncomfortable to crawl over sharp edges.

Diatomaceous Earth

Diatomaceous earth is made from fossilized algae and is a natural abrasive that can kill slugs. Sprinkle it around the base of your fern plant and on the leaves.

Copper Tape

Copper tape creates a barrier that slugs won’t cross. Place the tape around the base of your fern plant to prevent slugs from climbing up.

Chemical Remedies

If natural remedies don’t work, you can try chemical remedies. However, use them with caution as they can be harmful to humans and pets. Always follow the instructions on the label.

Slug Pellets

Slug pellets contain a chemical called metaldehyde that is toxic to slugs. Scatter them around your fern plant and on the leaves.

Slug Bait

Slug bait contains a chemical called iron phosphate that is less toxic than metaldehyde. Scatter it around your fern plant and on the leaves.
