Slug Copper Rings

About this clip

Slug Copper Rings Slugs put the brakes on the gardener's biggest enemy, slugs, as they are unable to attack plants surrounded by one of these copper rings. The copper ring forms a physical barrier around plants and also gives slugs an unpleasant shock-like sensation when they try and cross or climb the copper, caused by a reaction between the metal and the mucus they rely on to move.
