Here's a nontoxic way to keep slugs away from freshly planted plants: Reach into your pocket. Grab a few pennies and place the copper coins around the base of new plants. Instead of using chemical insect repellants, when slugs come crawling up toward the seedlings, they'll either get an electrical shock or be repelled by the copper. By adding coffee grinds as well -- which they hate -- you'll have a foolproof barrier to protect your plants for good.
