Copper kills slugs where as salt only dehydrates them, but they continue to live....Penny Ball for the garden. Pennies in the garden repel slugs and make hydrangeas blue. I love this idea. It looks old and new and beautiful.
These copper bands are one of the best, non-harmful slug repellants around. Slugs and snails hate copper because it causes a harmless electric shock-like reaction when they come into contact with it, so they crawl away. Bend them into rings and push them into the soil at the base of your plant.
Slug and snail deterrent ~~ Don’t dump out that last bit of coffee that you didn’t finish, throw it in a spray bottle and spray your plants to naturally deter slugs and snails. Also, you can make a slug “fence” around the garden with the grounds. This is a double bonus because as the coffee grounds deter slugs, they are also a great addition to soil and earthworms love them!
