Coffee Ground Uses

If you search online for uses of old coffee grounds you will find a lot of different ideas.  We tried a lot of the ideas to see which ones really work.  The following list are our top 5 favorite uses for coffee grinds that we found work really well

  1. Coffee as Fertilizer

Coffee is highly acidic (unbrewed grinds significantly moreso than brewed grinds).  This can have a negative effect on some of the plants you grow in a garden.  It is very beneficial to a lot of other types of plants.

Carrots, beats and radishes grow exceptionally well with coffee.  These types of plants you can use fresh coffee grinds while planting.  The coffee gives them energy and helps them sprout quickly.

Azaleas, hydrangeas, rhodendrons, camellias, roses and other acid-loving flowering plants also love coffee.  For these, mixing the brewed grounds with dead grass clippings or brown leaves works the best.  Combining the straw type material with washed coffee grounds neutralizes some of the acidity but draws out the nitrogen, potassium, and magnesium in the coffee that helps these flowering plants thrive

  1. Earthworms

Earthworms improve crop (or garden) productivity.  Their tunneling through the soil helps aerate which leads to a more stable soil structure.  Their paths through the soil not only lead to better drainage because of the tunnels they create, they feed on dead roots, leaves, and plants as they travel.  Their secretions increase nutrient availability.  Earthworms are attracted to coffee so adding used grounds can provide many benefits far beyond the grounds themselves

  1. Compost

The amount of nitrogen present in coffee makes it an excellent green matter.  Simply throw it onto the compost pile as you are finished drinking your brew and your compost pile will benefit greatly.  Make sure you keep your greens and browns in balance so that you compost equally and do not begin growing unwanted bacteria and molds.  However, if your compost is in balance it will even further attract the earthworms you desire to create a really healthy soil environment.

  1. Absorb Odors

Coffee grounds (fresh or used) can serve in ways similar to baking soda.  You can place it in the back of your fridge to absorb odors or use them as a soap to wash your hands after chopping garlic or onions.

The best part is that even after you use them for absorption you can still use them later in the garden as fertilizer or for composting.

  1. Flavor Enhancer

This is one of our favorites.  We have found that a really fine grind (like a powder) makes coffee useful to put in all kinds of recipes.  You can make granola bars, brownies, cookies, muffins, etc.  Everything tastes better with a little bit of coffee added.  When used as a flavor enhancer it is best to use fresh coffee.

To try some of this flavor enhancer head on over to our store and buy a bag to see for yourself!
