How to Keep Snails out of Potted Plants

Snails can be a real nuisance in potted plants, devouring leaves and stems and leaving behind unsightly droppings. Not only can they damage your plants, but they also reproduce quickly so an infestation can quickly get out of control. Here are some tips on how to keep snails out of potted plants so you can keep your plants healthy and beautiful.

1. Use Copper Tape

Copper tape is an effective way to keep snails out of your potted plants. The copper creates a small electric shock that snails avoid which prevents them from climbing up the plant pot. Simply wrap copper tape around the base of your pot or around the rim and snails will stay away. This method is particularly effective for small to medium potted plants.

2. Create a Barrier

You can also create a physical barrier using a variety of materials such as eggshells, crushed seashells, coffee grounds or diatomaceous earth. Simply sprinkle these around the base of the pot and snails will not crawl over them. The sharp edges of the eggshells or seashells are particularly effective at deterring snails. Be sure to replace the barrier every few weeks or after a heavy rain to ensure it remains effective.

3. Use Natural Predators

Another effective way to keep snails out of potted plants is to use natural predators such as nematodes, ground beetles or parasitic wasps. These predators will feast on snails, keeping their numbers under control. You can purchase these predators online or at a local garden store and simply release them into your potted plants. Be sure to follow the instructions carefully to ensure you introduce the correct predator for your plants.

4. Keep the Soil Dry

Snails thrive in moist environments so keeping the soil dry can be an effective way to keep them out of your potted plants. This can be achieved by allowing the top layer of soil to dry out completely before watering the plant again. You can also use a fan or dehumidifier to keep the air around the plant dry. Be sure to monitor the soil moisture levels regularly so you don't accidentally underwater your plant.

5. Clean Up Debris

Snails love to hide in debris around your potted plants, so keeping the area clean can help prevent them from taking up residence. Remove dead leaves, sticks, and any other debris around the plant to eliminate hiding places. This will also make it easier for you to spot any snails that do manage to get into the plant pot.

Conclusion

Snails can be a real problem in potted plants but there are many effective ways to keep them out. From using copper tape to creating a physical barrier to releasing natural predators, there are many ways to reduce the snail population in your potted plants. By keeping the soil dry and cleaning up debris, you can also prevent snails from taking up residence. With a little effort, you can keep your potted plants healthy and beautiful, free from snail damage.
