Hannah in Cleveland, Ohio, who has a blog called This Garden is Illegal, reminded me about the Starbucks Grounds for Your Garden program, where they give away free 5-lb. bags of used coffee grounds. Coffee grounds are great for side-dressing plants in need of a little nitrogen and there's some evidence that snails and slugs are repelled by caffeine. At high enough concentrations, it kills them. The amount of caffeine in used grounds might be enough to repel them, which is all I ask. Either way, I'm feeding my soil. The worms in my kitchen worm bin love coffee grounds, so maybe "outside" worms will too. Worm activity is good for the soil!
Corporate giant or not, I love Starbucks.
What a great idea, I will have to check it out. anything to repel slugs.. ick!
