Many of you may be looking for effective green tips. One tip is to recycle used coffee grounds. Coffee mixed with soil can be used as a natural fertilizer. Used coffee grounds provide gardens with an abundant source of nutrition. Recycling coffee grounds is not only beneficial for gardeners but it helps in reducing the amount of waste going into landfills.

Coffee grounds contain a high amount of nitrogen. When scattered across soil before rain or watering they will slowly release nitrogen into the soil. When compost is mixed with coffee grounds it causes the soil temperature to rise and stay hot for long periods of time. The high temperature kills weeds and will allow your garden to flourish beautifully. Coffee grounds are acidic, which benefits “acid loving” plants. For instance roses, camellias, blueberries, and azaleas all flourish when sprinkled with coffee grounds.

Recycling coffee grounds also helps to feed worms, and keeps troublesome insects away. Earthworms love to feed on used coffee grounds; it helps them grow and reproduce. Having lots of worms is an excellent way to keep a healthy garden. It is important to have worm activity in your soil; this mixes the soil and helps in mineralizing your vegetation. As you may know the odor of coffee is very strong, the odor can sometimes be too strong for humans. In the case of insects like ants, slugs, and snails the odor works as a repellant.

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