Compost & Coffee Grounds

In are article yesterday we discussed composting: how to compost and what the benefits are of composting. This reminded one of our readers of the benefits of one of her favorite drinks, coffee, to composting. Click here to view her comment. Consequently, we decided to talk a little more about this nitrogen rich resource. So we sought out gardeningknowhow.com for a little more clarification on the topic.

As we discuss urban environments, coffee is an ideal source for compositing and fertilizing for the gardener in more urban settings. Unlike other sources of composting materials coffee grounds produce fewer concerns for disease and can be added to a compost mix or added directly to the soil as a fertilizer. While you are composting your coffee grounds you can also add your coffee filters to your compost pile or mix.

When adding coffee grounds to your compost mix remember that they are considered green compost and will thus need a brown compost material added to it in the proper ratio (2:1. 2 parts green to one part brown). If you add ground coffee to soil as a fertilizer, it will not directly add nitrogen to soil however it will:

  • add organic material to the soil
    • improves drainage
    • improve water retention
    • improve aeration in the soil
  • help microorganisms beneficial to plant growth thrive
  • attract earthworms

Unwashed coffee grounds can

  • lower the pH (or raise the acid level) of soil, which is good for acid loving plants

Fresh coffee grounds are acidic while used coffee grounds are neutral. If you rinse your used coffee grounds, they will have a near neutral pH of 6.5 and will not affect the acid levels of the soil. To use coffee grounds as fertilizer, work the coffee grounds into the soil around your plants. Leftover diluted coffee works well like this also.

There are several other uses for used coffee grounds in gardening:

  • keeping slugs and snails away from plants
  • some people also claim that coffee grounds act as a cat repellent and will keep cats from using your garden as a litter box
  •  worm food if you do vermicomposting with a worm bin

What do you have around the house that you can use in your composting? Remember if you only have plants around the house, you can also do this: use your old coffee grounds. Separating organic endeavors from environmental endeavors is difficult because they both pay homage to nature and are essentially the flip side of the same coin. How can re-purposing items you typically throw away help you save money? What can that do for the environment? How can composting even on a small scale improve the quality of your food and health? What is the one food you eat the most of? How can growing that one food change your health and diet? Share your comments with the community by positing them below.
