Coffee grounds are acidic and a great natural fertilizer for roses, azaleas, evergreens, rhododendrons, blueberry bushes, camellias, and hydrangeas. Adding coffee grounds to the soil around hydrangeas can produce vibrant blue blossoms, because the extra acidity helps the flowers absorb aluminium, leading to a deep blue hue.

To keep cats away from your flower and vegetable garden beds, sprinke cofffe grounds to encourage them to go elsewhere. Coffee grounds around your indoor houseplants will deter kitty from snacking on the leaves.

Freshen the fireplace:

• Before you clean out your fireplace, sprinkle the ashes with damp coffee grounds to minimize flyaway dust and debris. When cleaning the hearth at the end of the season, sprinkle a layer of dried coffee grounds along the back and sides and leave them there to eliminate any leftover smoke odors.

Sweeten smelly hands:

• Keep a small cup of coffee grounds near your sink, and use them to scrub your hands after you’ve worked with garlic, onions, fish, or other smelly items. The grounds will absorb the odor and also help exfoliate the skin.

Natural deodorizer:

• Use dried coffee grounds as a natural deodorizer for the refrigerator, freezer, closets, or car. Dry a batch of coffee grounds, and then place them in an open container to absorb odors in the fridge or freezer. For closets and cars, place dried grounds in a piece of cheesecloth or a section of old pantyhose; tie off the ends and then hang.

Dye it:

• The tannins in coffee grounds make them effective for dyeing Easter eggs, fabric, or paper. Mix grounds with a little bit of water to create a slurry, and then dip the objects to be dyed into the mix. The longer you leave an item in the mixture, the darker the shade of brown you'll obtain. To create a streaky, antiqued look, rub the grounds into the fabric or paper.

Compost:

• And coffee grounds can be added to your compost pile.
