Coffee grounds have many virtues. A natural exfoliant, you might have heard they can be used as a body scrubs but did you know they also contain magnesium and potassium which will benefit your vegetable patch? Here are 7 DIY recipes you can try to reuse your coffee grounds in and around the house!
1. Homemade Coffee Scrub
Many exfoliating scrubs contain plastic micro-beads which are not biodegradable and pose a serious threat to the environment. Due to their microscopic size, these plastic particles cannot be filtered in wastewater treatment plants and flow directly from your bathroom into waterways and eventually end up in the ocean.
Coffee grounds are naturally cleaning, degreasing and abrasive. They will gently help get rid of dead skin and stimulate blood circulation. For a gentle exfoliating product, mix the coffee grounds with vegetable oil with moisturising properties, especially if using the scrub on the face of sensitive skin.
4 tablespoons of coffee grounds
5 to 6 tablespoons of the vegetable oil of your choice (olive, coconut, argan ...)
Pour the coffee grounds and vegetable oil into a bowl and mix.
Apply in the shower on wet skin in circular motions using your fingers or a glove. Rinse well with clean water and moisturise your skin once dry.
If you have any leftovers, pour the scrub into a small glass jar or an airtight jar. The body scrub will keep for about 6 months at room temperature.
If you are used to essential oils, you can also add 2 to 3 drops of lavender essential oil to the mix for a soft, soothing scent.
2. Natural Fertiliser
Coffee grounds contain magnesium, potassium and nitrogen. These properties are particularly interesting for your vegetable patch and make coffee grounds an excellent natural fertilizer.
Slightly acidic, they are ideal to help strengthen the blue colour of hydrangeas and will also give a great boost to tomatoes.
Spread the coffee grounds at the base of the plants - the coffee grounds must be very dry and used in small quantities.
Mix the coffee with the soil.
3. Coffee as a Natural ant Repellent
Coffee Grounds can also be used as an ant barrier! Mix coffee grounds with a few drops of lemon and make a "wall" where the ants pass. They will stop coming!

The grounds will flow through your plumbing and naturally clean the pipes. This will prevent your sink from getting clogged up with fat from food waste.
