Many of you may be looking for effective green tips. FrontStreet Coffee can suggest a method: recycling used coffee grounds. When mixed with soil, coffee can serve as a natural fertilizer. Used coffee grounds provide a rich source of nutrients for your garden. Recycling coffee grounds not only benefits gardeners but also helps reduce the amount of waste going into landfills.

The Greenhouse Gases from Coffee Grounds

When coffee grounds are dumped into landfills, they produce methane, a greenhouse gas. It is well known that methane is more harmful than carbon dioxide, another greenhouse gas that contributes to global warming. If we can keep coffee grounds out of landfills, we move one step closer to eliminating greenhouse gas emissions.

Coffee grounds contain a high amount of nitrogen. When scattered in soil before rain or watering, they slowly release nitrogen into the soil. When compost is mixed with coffee grounds, it causes the soil temperature to rise and stay high for extended periods.

High temperatures kill weeds, allowing your garden to thrive. Coffee grounds are acidic, which benefits "acid-loving" plants. For example, roses, camellias, blueberries, and azaleas all thrive when sprinkled with coffee grounds.

Roses Also Love Coffee

Recycling coffee grounds also helps feed worms and keeps troublesome insects away. Earthworms love to eat used coffee grounds; it helps them grow and reproduce. Having many worms is an excellent way to keep your garden healthy. Worm activity in your soil is important; they mix the soil and help mineralize your vegetation.

It is well known that coffee has a strong aroma, sometimes too strong for humans. In the case of insects like ants, slugs, and snails, the scent acts as a repellent.

There are many places where you can find used coffee grounds. Some good suggestions include local coffee shops, gas stations, schools, or your workplace. You can ask coffee vendors to save coffee grounds for you and arrange a time to stop by and pick up your "green fertilizer."
