Coffee grounds can add nitrogen, which all plants need, but it is somewhat acid. I'd use it for acid-loving plants like azaleas, rhododendrons, hollies and hydrangeas. My dad, a landscape architect, added used coffee grounds to our ivy beds.
Apply it lightly and maybe work it into the soil. You don't want it to create a crust or get moldy.
