With so many injustices in the world, it’s a great feeling to know where you get your ethical coffee from. Being aware of who’s growing your favorite beans makes you more confident in the brew and lets you sip easy knowing it’s sourced sustainably. If you’re looking to cut down your carbon footprint even more, then re-using old coffee grounds is a good investment. To get the most out of the grounds, these three plants can’t get enough of your coffee’s waste.
Rose bushes may be a pain to grow, but coffee could be your trick. Roses love the high nitrogen content in coffee; putting grounds in your soil also helps spread the soil out which gives the roses more room to grow. You can simply sprinkle bits of coffee grounds around the roots of your rose bush, or you can mix the grounds with water and pour it on your budding bush once or twice a month.
You’ll see a big benefit in how your hydrangeas look when they absorb coffee’s nutrients. The colors of the flower will be brighter and more vivid. In addition, the plants will be stronger and healthier. Add the leftover coffee grounds around the soil where the plants are to see your flowers flourish.
If you normally grow blueberries, you know they don’t really benefit from fertilizer. However, like roses, these plants savor the high nitrogen presence in coffee grounds. Every two weeks, add about five cups of coffee grounds around your blueberry plants, and mix it in with the top layer of soil. This will enable the roots to soak up the benefits coffee has to offer your blueberries.
In the U.S., a single person produces a little over 4 pounds of trash a day which adds up to a whopping 250-millions tons of waste a year. However, finding small ways to reuse and recycle old coffee grounds is one way to lessen your load on the environment.
