How to Get Rid of Snails on Green Onion Plant

Updated: July 17, 2022

Green onions are a great addition to any garden or kitchen, but they can be vulnerable to snail infestations. Snails can cause damage to the leaves and stems of green onion plants, which can ultimately affect their growth and yield. Fortunately, there are several ways to get rid of snails on green onion plants without using harmful chemicals. In this article, we will discuss some effective methods for deterring snails from your green onions.

1. Handpicking

One of the easiest and most effective ways to get rid of snails on green onion plants is by handpicking them off. This method may seem tedious, but it is a natural and chemical-free way to control snail populations. To handpick snails, simply go out to your garden in the early morning or evening when they are most active and pick them off one by one. It’s important to dispose of the snails properly, as they can quickly re-infest your garden if left nearby.

2. Copper Tape

Another effective method for deterring snails is by using copper tape around the base of your green onion plants. Snails do not like crossing copper surfaces, so placing a band of copper tape around your planters or beds can help prevent snail infestations. This method also works well for other types of plants that are prone to snail damage.

3. Beer Traps

Beer traps are a popular and effective method for controlling snails in the garden. To make a beer trap, simply bury a small container (such as a yogurt cup) in the soil near your green onion plants and fill it with beer. The scent of the beer will attract snails, and they will crawl into the container and drown. This method not only controls snail populations but also helps recycle beer cans or bottles.

4. Eggshells

Eggshells can be a natural and effective snail deterrent. Simply crush up eggshells and sprinkle them around the base of your green onion plants. Snails do not like the rough texture of the eggshells, so they will avoid crawling over them. This method also provides a source of calcium for your plants, which can help promote healthy growth.

5. Diatomaceous Earth

Diatomaceous earth is a natural substance that can be used to control snails in the garden. It is made of fossilized diatoms, which are tiny aquatic organisms with sharp edges that can cut through the soft bodies of snails and other pests. To use diatomaceous earth, simply sprinkle it around the base of your green onion plants or directly on snails that you find in your garden.

6. Companion Planting

Companion planting is a method of planting different types of plants together to create a mutually beneficial relationship. Some plants are known to repel snails, such as herbs like rosemary, sage, and thyme. By planting these herbs near your green onions, you can help deter snails naturally.

Overall, there are several effective ways to get rid of snails on green onion plants without using harmful chemicals. Handpicking, copper tape, beer traps, eggshells, diatomaceous earth, and companion planting are all great options to consider. By using one or more of these methods, you can help protect your green onions from snail damage and ensure a healthy harvest.
