How to Deal with Slugs and Snails on Coral Bells Plants

by

Coral bells plants, also known as Heuchera, are popular for their vibrant foliage and delicate flowers. However, they are often vulnerable to pests like slugs and snails, which can cause significant damage. Knowing how to manage these pests is essential for maintaining healthy, beautiful plants.

Identifying Slugs and Snails on Coral Bells

Slugs and snails are soft-bodied mollusks that are most active during damp, cool conditions. They leave behind slimy trails on the leaves and soil surface. You may notice irregular holes or ragged edges on the foliage, indicating their presence. Slugs tend to be smaller and more active at night, while snails are often seen during the day.

Preventive Measures

  • Maintain good garden hygiene by removing debris and fallen leaves.
  • Ensure proper drainage to reduce excess moisture.
  • Apply a layer of mulch around the plants to deter slugs and snails.
  • Encourage natural predators such as birds, frogs, and ground beetles.
  • Use copper barriers or strips around the plants as a physical deterrent.

Manual Removal Techniques

Regularly inspect your coral bells, especially in the early morning or evening. Handpick slugs and snails and dispose of them far from your garden. You can also set out shallow dishes of beer or a yeast solution to attract and trap these pests.

Natural and Organic Control Methods

Several natural options can help control slug and snail populations:

  • Iron phosphate bait: Safe for plants and pets, it attracts slugs and snails and kills them after ingestion.
  • Diatomaceous earth: Sprinkle around plants to create a rough surface that damages their bodies.
  • Neem oil: Acts as a repellent and disrupts their feeding habits.

Chemical Control Options

If natural methods are insufficient, chemical slug and snail baits containing metaldehyde or methiocarb can be used. Always follow the manufacturer’s instructions carefully to avoid harming beneficial insects and pets.

Additional Tips for Healthy Coral Bells

Healthy plants are more resistant to pests. Ensure your coral bells receive proper watering, fertilization, and placement in suitable light conditions. Regularly monitor for signs of pests and act promptly to prevent infestations from spreading.
