Stop Slugs and Snails from Eating Your Grow Table Crops Right Now With This ONE Simple Trick

I made a quick video which runs down the key points for you of how to employ this method. There is no sound on it so you can watch it without being concerned about audio. As well as the video, I have covered this method of natural slug prevention in more detail below for you to read either instead of or in addition to the video.

Here's a detailed run-down of using this natural method of slug and snail prevention.

The Benefit of Using Grow Tables is in the Legs

Grow tables are a very useful way to grow crops and although they raise the height of the crop level away from the ground, it is still incredibly easy for slugs and snails to climb up and munch away on your crops.

I've tried lots of natural and organic slug control methods including crushed egg shells and copper tape but never had any real success. Until I realised that water was the most natural barrier to prevent these creatures from getting to my crops.

Grow tables normally come with legs attached. This makes it super easy to employ my quick and easy slug off trick.

What You Need to Employ This Easy Trick

You need 4 wide and strong containers. A sturdy tin or pot with no drainage holes is absolutely ideal. We had some old metal baby formula tins and weight loss powder tins which were ideal for this.

Stand each leg of your grow table in one of these wide containers. Make sure the table legs do not touch the side of the containers at all.

Add some water inside each container. I fill mine about half full and have never had to refill them with the amount of rain we get.

The water in each container creates a barrier which normal garden slugs and snails are simply unable to pass. They will climb up the side of the tin, then down inside it but have to turn back once they realise there is water there.

The containers have to be wide so that slugs and snails are unable to stretch their bodies over the gap of water.

I'm very happy with my black plastic Elho grow table and went back and bought another because I've found it such a useful addition to my vegetable garden.

Some Extra Notes on Using This Natural and Organic Method of Slug Prevention

If you are concerned about whether this method is humane - it is. The water is there not to kill the slugs but to provide a natural and organic barrier which they are unable to pass. I've yet to find any drowned ones and I've seen them trying their best to get up to the goodies in the grow table.

Should looks matter to you, you can always paint the containers to match the overall color of your grow table. For me, I'm not bothered about how it looks because my priority is having a productive vegetable garden rather than a show garden. I don't have time to do both.

Metal tins will normally rust over time but they are much stronger to cope with the weight of a grow table which is full of compost and plants. It is possible to line them with a waterproof liner or a waterproof paint to extend the life span of the tins.

Plastic containers would have to be tough plastic to take the weight of the grow table or they will crack and split.

If you have a wooden growing table, you can use a thick, waterproof liner around the bottom of the legs to protect them from the water surrounding them. There is no need to worry with a plastic table like the Elho ones I have.

Make sure that slugs and snails cannot access the grow table any other way. If it is touching a fence, wall or even a plant growing by its side then you are leaving the way clear for these creatures to access their favorite foods.

Here's a Quick Recap of Stopping Slugs Eating Your Grow Table Plants
  1. Stand each leg of your grow table in a wide container.
  2. Fill each container about half way with water.
  3. The water creates a natural and organic barrier which slugs and snails cannot pass.
  4. It is a humane method and the water is not there to kill these creatures, just to stop them climbing up your grow table.
  5. Make sure that these garden pests cannot access your plants easily any other way such as if the table is touching a wall, fence or even a plant growing at the side of it.
  6. Keep the water topped up or they will be able to climb up as normal.
Enjoy eating fruit and veggies without the usual nibbles and holes from our favorite garden pests.
