Coffee can be used for more than just waking you up in the morning. Your coffee ground can find a second life, and be used for plenty of useful applications around the house. Here are some of them:
- Pest repellent
Sprinkle used coffee grounds around your plants to protect them against destructive garden pests like ants, snails, and slugs. It has even been said that old grounds mixed with dried orange peel will keep away some small mammals like cats. If coffee and orange peel doesn’t work, try rosemary oil instead.
Used coffee grounds are also an excellent mosquito repellent, as mosquitoes hate the strong smell that used coffee grounds have. In addition, it is a scientifically proven fact that coffee possesses the ability to destroy mosquito larvae before they hatch,
- Garden fertilization
If you grow azaleas, hydrangeas, rhododendrons, camellias, roses, or other acid-loving plants, then used coffee is the fertilizer for you. Mix your old grounds with dead grass clippings, brown leaves, or dry straw to neutralize some of the acidity, the spread them around your plants. Used coffee grounds add nitrogen and potassium to the soil, as well as a boost of magnesium which all plants need to stay healthy. Just remember that this fertilizer lacks phosphorus and calcium so it isn’t ideal for encouraging blooms and fruiting. You’ll need to add lime or wood ash to the mix if you want to create a complete fertilizer using old coffee grounds.
- Cleaning out the fireplace
Gently scatter old used coffee grounds over the ashes to weight them down and prevent the huge clouds of smoke that often arise when performing this arduous task. Not only will shoveling the ashes be easier than ever before, you also won’t have to wipe down every horizontal surface in the room when you’re done.
4. Removing odors from your fridge
Used coffee grounds can be used much like baking soda for absorbing food odors in the refrigerator and freezer. Just load up a small open container with your old grounds, place it in the back of the fridge, then forget about it for a couple of weeks while you collect more grounds. As an added bonus, after you remove smelly old grounds from the refrigerator or freezer, you can then toss them on the compost pile or use them for fertilizer.
- Hiding furniture scratches
Dip a cotton swab into steeped grounds and dab on scratches in dark wood furniture to minimize them. Just test in an inconspicuous area first, as this method doesn’t work on all types of wood.
- Staining wood
Coffee grounds have an ability to give wood a nice and organic tone. You will need to place your leftover coffee grounds into a coffee pot. Add boiling water on top, and let it sit for at least two hours. Filter out the coffee grounds into a container that can fit a paintbrush. Soak the brush in the mixture and apply to the wooden area you wish to stain. The layer will need 10 minutes to dry, and then you can apply the next one, repeating the procedure until you’ve achieved the wanted tone.
