We can use used coffee grounds for our garden. It is natural for the plants, so it is very beneficial for plants.
One creature that does love coffee grounds is perhaps the most beneficial to the garden, these being earthworms. From my own experience and from many others, they love the stuff, are attracted to it, and your soil will be healthier as a result.
Just apply cooled, used coffee grounds around your eyes and sit back and relax for twenty minutes before washing them off.
