Product Information

According to the RHS, some slug species have clear benefits for gardeners, such as the leopard slug, which eats fungi and rotting material, helping recycle garden nutrients.

Great to see… to add to the video list, I liked this one on the topic: http://www.youtube.com/watch?v=ZFn9TT_rlXU SPECIAL OFFER - These His and Hers Solitary Bee Houses are wall mountable wooden bee houses that have been designed… Storage & Home Clearance Furniture Clearance Garden & Outdoor Clearance Lighting Clearance Electrical Clearance Tools Clearance Paint & Decorating Clearance Flooring & Tiling Clearance Building & Hardware Clearance Bathrooms & Plumbing Clearance Kitchens Clearance After tending to the crop for weeks Hayley harvested the lettuces and removed the leaves one by one. She then rated the damage visually and useda leaf area meter for the first time,to record the damage in every square cm of the leaves.

How we tested the barriers

Use this attractive, dual purpose Butterfly House and Feeder to offer butterflies food in the summer and shelter in the winter.… As existing lab studies have shown some of the barriers work, and as other experiments by Hayley hinted that copper tape could be effective, she’s not ruling the barriers out completely. She hopes to run the study again ona different slug population and different soil type at RHS Garden, Harlow Carr in 2019. Jeff Gillman, one of the Garden Professors, commented “When I’ve tested copper the slugs seemed to have a slight preference for not crossing it, but would if that was what they need to do to get where they were going. I’d call it a mild repellant” . I think this is a good summary. Slugs will not go out of their way to cross copper in tape form, but it is not a fool proof solution.

My friend suggested garlic water sprayed on the plants and left to dry. Apparently they don’t like the taste. Reapply every 2 weeks. Recipe below. Does this work? While this research hasn’t shed any light on what you can do to obstruct slugs and snails, it has at least shown that these barriers can be unreliableand ineffective. I’ve tested solid copper rings which I made from some spare copper roofing strip. Did it work? Yes and No; the difference is oxidation. Copper pennies and wire do not seem to work. Most products on the market are a type of copper foil or copper tape so this might work better and in fact some people suggest that a wider strip is better than a narrow strip. As members of the Mollusca group of animals, slugs and snails use Hemocyanin proteins in their blood to transport oxygen around their bodies ( whereas we mammals use iron based Hemoglobin). These Hemocyanin proteins contain two copper atoms. This makes all molluscs very sensitive to the ingestion of additional quantities of copper. Too much copper and it prevents oxygen from moving around their bodies and they eventually die, unless they flee to safety.Efficacy and environmental fate of copper sulphate applied to Australian rice fields for control of the aquatic snail Isidorella newcombi Simple test. Fit copper tape round terracotta pot. Place 6 slug pellets on top of pot. Leave over night. I am not a chemist but guess it is due to some kind of ion exchange or electron donation. My guess is that something similar is taking place between the bright copper and the molluscs. Roofing metals are chosen for the job because their oxides adhere to their surface and are chemically inert under normal atmospheric condition. Knowledge of this fact is what lead me to triy the experiment in the first place. While you could choose to grow a range of slug-proof plants, like rodgersia and brunnera, slugs may also be repelled from your container-grown plants if you fix copper tape to your pots. Copper tape is thin, easy to cut and simple to apply. Plus, it will gradually turn green over time, giving it an attractive aged look.

Copper sulphate is made by combining copper alloy with sulphuric acid. Whilst sulphur dioxide emissions from power stations have dropped enormously in Western Europe since the 1980s, there is still enough in the atmosphere for rain to contain traces of sulphuric acid. In certain places within the UK you will be receiving higher doses of sulphuric acid in your rain than others. What happens when this acid rain lands on copper alloy tape on your outdoor plant pots? It makes trace amounts of copper sulphate which runs down your pot and into the soil. I therefore put it to you that as the copper tape weathers, in some areas it releases traces of copper sulphate which makes it even more potent, especially on more porous terracotta pots that can hold onto the copper sulphate. If you live in a city there’s probably more chance of copper tape having this effect than if you live in the countryside. I can’t prove that it exists but it would seem logical. Of the thousands of enquiries received by RHS Gardening Advice every year, deterring slugs and snails is atop concern. To ensure we aregiving the best advice on this much-debated topic, we set up a project – Gastropod Barriers– to test whether the most commonly recommended home remedies really work. How we tested the barriers Copper DOES work as a slug and snail barrier if the percentage of copper alloy is high enough and the width is in excess of 4 cms.”

You may be correct. As I said I am not a chemist. Although I’m not sure that ‘Conducting current’ is the same as ‘exchanging an electrical charge’. But who really cares. The issue is whether or not it works and if so, under what conditions. My criticism of your comments on ‘Electrical current’ as it related to the use of copper is that it represented a deductive approach not an empirical one. Things often fail or succeed for reasons other than we anticipate. There is no substitute for testing. Copper DOES work as a slug and snail barrier if the percentage of copper alloy is high enough and the width is in excess of 4 cms. Don’t waste money on any of the other ‘gardening’ products tested above and be cautious of using anything else that comes in a similar sized box ( or from a matching production line…).

Regardless of the use of copper strips or electricity, some types of slugs have been know to drop down from overhanging trees or even lower themselves down a slime trail.Encourage their natural predators into your garden by creatinga haven for wildlife, such as birds and frogs. The attention to detail in this study, and the use of the leaf area meter, lets us be more precise and confident in the results." What’s next for slug and snail research? If you want to protect your plot from slugs and snails, these trialled remedies just won't cut it. You may need to try something different. What can I do? These methods were tested on 108 lettuces sown in pots and raised beds at the RHS field research facility in Wisley. After six weeks, the leaves of each harvested lettuce were examined to calculate damage. I’m so chuffed I found this piece of yours! Ha fantastic! Really appreciate the time you’ve taken on the copper tape to pass it on to everyone .How generous of you .Saving us time effort and much needed cash ..I too love anything with Monty Don and sobbed last night after watching Gardeners World to hear Nigel had passed away.
