1. Fertilize Your Plants
It isn’t the caffeine in coffee grounds that plants like azaleas, rosebushes, and evergreens love but rather the acidity and aeration the grounds provide-not to mention nitrogen, phosphorous, and trace minerals. Be sure to dig the grounds into the soil to keep them from becoming moldy, but don’t overdo it: Dig about 3/4 cup of grounds into the soil near the roots, repeating once a month. Fertilizing even acid-loving plants with coffee grounds too frequently could increase soil acidity to undesirable levels.

2. Eliminate Pet Odours
Some pet owners have found they can remove pet odours from a room by heating a cupful of freshly ground coffee beans in a cast-iron skillet over low heat. As soon as the scent is released, remove the pan to the smelly room, and set it on a trivet. By the time the ground beans are cool, much of the pet odour should be gone.

3. Exfoliate Your Face
Chris Barnes notes in a Stylelist feature that you can exfoliate your skin with coffee grounds. Rub the moist grounds in gently to get rid of dead skin, then rinse.
