Is there such a thing as truly useless refuse? I’d think not, particularly in light of the wealth of information on how to reuse things of little value. Things that most people undervalue, for example, glass, lumber, wood pulp, paper, used rubber tires, and in the scope of this report. As it turns out, this treasure, in this case, used coffee grounds, can be put to more than one use, in fact, I can list 15 uses at the moment.
1. Insect control
Insect control – There is currently an internet meme going around that spraying used coffee grounds on your skin and plants will repel mosquitoes, particularly ones that carry Zika Virus. There is in fact no scientific literature to demonstrate this, though there are some signs research-wise that spraying coffee and used coffee grounds on mosquito breeding sites inhibited the embryogenesis of mosquito larvae, and thus significantly reduced the number of mosquito larvae that successfully matured into adults.
For plants that like acidic soil, like hydrangeas, rhododendrons, camellias, roses, blueberries, magnolia trees, etc.. Used coffee ground can serve as a source of fertilizer. Some flowers will even change colors depending on the pH level of the surrounding soil, so put the blue in your hydrangea blossom, with used coffee grounds!
3. Carrots and radish growth
Carrots and radishes work great with used coffee grounds. Sprinkling the latter on the former before planting will help the small seedlings grow faster and provide an extra boost when they’re just germinating, you are sure to reap larger produce as a result.
