RE: Why Are Coffee Grounds Good For Plants
Coffee grounds are acidic and some plants, like azaleas, like acidic soil. Old, leftover coffee works, too. (10/28/2007)
I found this on nbc4.com:
Q: I heard that used coffee grounds are good for
plants. Is that true?
A: We contacted the Montgomery County Department of Environmental Protection for your answer. It says yes, coffee grounds are good for plants because they're a rich source of nutrients for plants and they acidify the soil. Coffee grounds are great for acid-loving plants like azaleas, blueberries, and hydrangeas. Just spread the used grounds over the roots. Don't use coffee grounds in the soil of roses, because those plants prefer a basic soil. (11/01/2007)
