The specific angles of the slug collar means the slug cannot climb over it, and so cannot access your plant. This acts as a physical barrier. Then the plants are protected not only from slugs but also, for example, from the cabbage white butterfly and similar pests. Also, suitable is self-adhesive copper tape, which should be at least two inches (five centimeters) wide. Narrow copper strips can too easily be overcome by persistent slugs.

liters) plastic bottles are a good fit for larger plants, while 16oz (~1 liter) bottles are enough for small plants. Snails hibernate over autumn and winter, often under small, covered places in your garden like stones, logs and pots, whilst slugs are active all year-round.

Garden Grow Snail Collar

Just like snail fences, snail collars are also available in metal and plastic and have corresponding properties. Their mode of action is also based on the same principle. A special feature of the slug collars is that they can also be converted into a mini greenhouse. Since they are quite small, a lid can be placed on the opening, protecting the plants from frost, drying or heavy rain. An upgrade is possible with close-meshed fruit and vegetable protective netting or fly screens, which also keep out other garden animals. For this, I placed marigolds inside a slug collar and put some freshly collected slugs and snails around it. Transforming old drinking cups and yogurt pots into snail collars does not require a lot of prior manual knowledge.

They like a wide variety of plants, particularly hostas, tulips, dahlias, gerberas, sweet peas, and delphiunims.

In this case, one can consider removing nontransparent collars on sunny, dry days and only use them at night. The collars come with an optional extra of lids that can be used to create a mini greenhouse effect for germinating seeds. The small holes in the top of the lid allow you to water your crops without removing it, making it easy to keep your plants hydrated and healthy.

For small plants, non-transparent models are not ideal, but for larger plants, this is not a problem. With a beer trap, you set a container, usually a plastic tub of some kind, level with the surface of the soil. You want it level with the surface so slugs can easily get into it but you want the bottom to be deep, so they can’t get out. The product: Reusable physical barrier to prevent slug and snail damage. An internal diameter of 13cm makes them suitable for individual plants (e.g. Hostas), salads, vegetables and even any supporting canes.This is one of the largest slugs in British gardens, reaching up to 15cm in length and living up to 3 years. It is pale with distinct leopard-like spots. It also tends to mate above the ground, from a string of mucus. Slug fences surround an entire bed and serve as a slug barrier. To get inside, snails would have to overcome this obstacle. However, this is difficult because of the previously described structure of the snail fence – as long as care is taken to avoid gaps in the snail fence and also to avoid plant parts hanging over the slug barrier, which would act similar to a bridge. Of course, old gutters made of copper are also suitable without water as a form of protection against the slugs. When trying to crawl around the edge, they fail to do so or fall down. Therefore, one can attempt to recreate a similar sharp edge. This is a simple, long-term solution to deal with slugs and snail infestation, with no need for toxic chemicals or any maintenance.

The RHS study also found other natural slug deterrents like bark mulch, eggshells, sharp grit or wool pellets, to be ineffective in their study, with zero reduction in slug damage. These edges are difficult to overcome for slugs, as they are too sharp for the animals to climb around the corner.

Garden Ready Plugs

Particularly suitable for this purpose are cups with a wide edge/rim, which, like the original snail collar, extend far with a sharp point around the corner.
