How to Get Rid of Snails on Rhubarb Plant

Introduction

Snails can be a nuisance for gardeners, especially when they start feasting on your precious rhubarb plants. These slimy creatures can cause significant damage to the leaves and stems, affecting the overall health and productivity of your rhubarb. In this article, we will explore effective methods to get rid of snails and protect your rhubarb plant.

Understanding Snail Behavior

Before we delve into the various control methods, it’s important to understand the behavior of snails. Snails are nocturnal creatures that thrive in humid conditions and feed on a variety of plants, including rhubarb. They leave behind a trail of slime as they move, which can be easily spotted on the leaves and stems of your plant.

Snails prefer to feed during the night when temperatures are cooler and humidity levels are higher. They hide in dark, moist places during the day, such as under rocks, pots, or debris. Understanding their behavior will help you implement more effective control strategies.

Manual Removal

One of the simplest ways to control snails is through manual removal. This method involves physically picking off the snails from your rhubarb plant and disposing of them away from your garden. While it may not completely eliminate the snail population, it can significantly reduce their numbers.

To manually remove snails, inspect your rhubarb plants during the early morning or late evening when they are most active. Wear gloves to protect your hands from their slime and carefully pick them off one by one. Dispose of them in a sealed container or relocate them far away from your garden.

Natural Predators

Introducing natural predators can serve as an effective biological control method for snails. Certain animals and insects prey on snails and can help keep their population in check. Consider attracting or introducing these predators into your garden to aid in snail control.

One such predator is the common garden toad. Toads are known to feed on snails and can be beneficial in reducing their numbers. Create a toad-friendly environment by providing them with hiding spots, such as overturned clay pots or dense vegetation. Additionally, avoid using chemical pesticides that may harm these beneficial creatures.

Another natural predator of snails is the decollate snail. These small, cone-shaped snails feed exclusively on garden snails and can be an effective means of biological control. Contact your local agricultural extension office or nursery to inquire about the availability of decollate snails in your area.

Barrier Methods

Using barrier methods can effectively prevent snails from reaching your rhubarb plants. Snails have a difficult time crossing certain textures and materials, making it harder for them to access your plants.

One common barrier method is the use of copper tape or copper wire. Snails receive a mild electric shock when they come into contact with copper, deterring them from climbing over it. Apply a strip of copper tape around the base of your rhubarb plant or create a barrier using copper wire to protect the stems and leaves.

You can also create barriers using rough-textured materials like crushed eggshells, diatomaceous earth, or gravel. Sprinkle these materials around the base of your rhubarb plants to create an uncomfortable surface for snails to traverse.

Natural Repellents

Certain natural substances act as repellents and can deter snails from approaching your rhubarb plants. These repellents work by emitting odors or tastes that snails find unpleasant, causing them to avoid the treated areas.

One effective natural repellent is garlic. Create a garlic spray by blending several cloves of garlic with water and straining the mixture into a spray bottle. Apply this garlic spray onto the leaves and stems of your rhubarb plants, reapplying after rainfall or every few days for optimal effectiveness.

Another natural repellent is coffee grounds. Sprinkle used coffee grounds around the base of your rhubarb plants to create a barrier that snails find unappealing. Additionally, coffee grounds can act as a fertilizer, enriching the soil around your plants.

Conclusion

Snails can pose a threat to the health and productivity of your rhubarb plants. However, with the right control methods in place, you can effectively manage their population and protect your garden. Implement manual removal, attract natural predators, use barrier methods, and apply natural repellents to keep snails away from your rhubarb plants. By doing so, you can enjoy a thriving rhubarb harvest without the interference of these slimy pests.
