Q: As you may know some coffee shops give away free coffee grounds. They say they are good for your garden. My question is how should they be applied? Should I mix them straight into the soil? If so how much at a time? Or should they be used as part of compost?
A: You can use the coffee grounds in your garden or in your compost equally well. The grounds are acidic so mix a tablespoon of garden lime into a five pound bag before you dig them into your garden or put them on the compost pile. In the garden, mix at a rate of five pounds per three square feet. For composting, mix at a ratio of five pounds per three cubic feet of yard waste.
