When I make a cup of coffee I always put the used coffee grounds in the compost pile. Coffee grounds add nitrogen to the pile. I read online somewhere that Starbucks has a program called grounds for gardens. I went to Starbucks to grab a latte and asked them if I could have some coffee grounds. They said sure… and gave me a 30 pound bag of coffee grounds. I added it to my presto hoop bin. The coffee grounds made the compost pile really heat up. I put some of the coffee in my worm bin and it made the worm bin too hot. I think moderation is the key in a worm bin. Coffee grounds could be used to keep the worm bin warm in the winter.
