Go to Starbucks and ask them for their used coffee grounds and then add it to your compost. Or you can use small amounts in your soil, but I've never done that. Too much of it, uncomposted, in your soil could throw off the pH.

Coffee grounds are good in compost, or around plants that need acidic soil.
