Use coffee grounds in your compost heap along with other "green" kitchen waste, then use the compost to dress the soil around your rosebushes. 2. Feed roses coffee directly. Once or twice a season, sprinkle a cup of dried, used coffee grounds on the soil around each rose bush, then lightly dig it in.Jul 21, 2017
How do you sprinkle coffee grounds on plants?
