What's better than sitting in the garden with good friends and neighbors, enjoying a cup of coffee? The question often comes up about the benefits of using coffee grounds in the garden. The simple answer is coffee grounds are a great addition to your garden and to the compost pile. Coffee grounds can help improve your garden soil by adding micro-nutrients, improving soil structure and by encouraging earthworm and microbial activity. The common thought is that coffee grounds will help acidify your soil. Coffee grounds tend to be pH neutral, around 7 on the pH scale. The acid in coffee is water-soluble, so the acid is mainly in your coffee cup, not in the coffee grounds. It's still worth while to add coffee grounds to your soil because doing so will help move your soil towards neutral pH, which is good for most plants. Coffee grounds can also improve soil structure and drainage.
