Adding used coffee grounds to the plants in your garden and home is a very beneficial way to provide them with the much needed nutrients that may otherwise lack. Nitrogen is one of these important nutrients that the soil will absorb, providing the plant with a mineral that is otherwise very hard for the plant to come by. Reusing coffee grounds is not only very beneficial for your plants, but it is also a very simple process that will cost you no extra money!

Coffee grounds are acidic, so they will most benefit acid-loving plants such as Gardenias, Hydrangeas, Roses, Ferns, Phlox, and Calla Lilies. Many evergreen and deciduous trees, as well as shrubs also benefit greatly from coffee grounds.

For your houseplants, you can simply lightly mix in with the soil. For your outdoor plants, just sprinkle them around the plant before watering. Both these techniques provide a slow release of nitrogen. Be careful not to use too much because if the grounds become packed down, they can become too heavy for the ground and decrease aeration.

You can also add coffee grounds, filter and all, to your compost pile to enrich the eventual outcome. Once everything decomposes, you'll have an extra rich soil product that will even assist in preventing weed growth. To achieve a better soil result, it's good to mix the grounds with dried lawn trimmings, leaves and other brown material. Also, many pests will avoid a garden that is fertilized with coffee grounds.

It is quite simple to provide your garden with extra nutrients that can be found in your used coffee grounds. Not only does reusing your coffee grounds save you from having to purchase special fertilizers, it also highly benefits many plants in your garden!
