Using coffee grounds in the garden is a great way to add organic matter to your soil. Coffee grounds are a good source of nitrogen for your garden soil. Being naturally acidic in nature, used coffee grounds are wonderful for acid loving plants such as roses, blueberries, camellias, azaleas, and rhododendrons. If you don't drink coffee very often, you may find coffee grounds for the garden at your local coffee shop. Starbucks, in particular, has a "Grounds for your Garden program" where they give you a 5 lb bag of used coffee grounds for FREE.
Most coffee shops are more than
willing to give you all the coffee grounds your garden can handle, that way something that would normally get thrown out, gets used for something good. Sprinkle them around the base of the plant, on the ground. Be careful not to add too
thick of a layer or mold may develop. A nice thin layer of
coffee grounds around the trunk of the plant is all that is needed. One more
added benefit of using coffee grounds in the garden is that earthworms love the
used coffee grounds. They will feed on the coffee grounds and in turn aerate and
fertilize the soil around your plants. You'll always enjoy the rewards of using
coffee grounds in the garden. Sprinkle them around the plant or add them to your compost.
