Garden Tips 🌿

As said above, coffee grounds are a natural waste, made simply from ground coffee and water.And due to its composition, it is excellent as a natural fertilizer, but also as a repellent!

Boost your compost

If you own a composter, it's good to know that earthworms love coffee grounds, which help them digest organic matter. Their sensitivity to caffeine increases their activity in converting plants into compost! Coffee grounds are therefore ideal for enriching your compost.


A study published in Waste Management showed that coffee grounds can be composted if the correct proportions are used. Researchers found that a batch of compost containing 40% coffee grounds produced higher-quality compost and lower greenhouse gas emissions.

Natural repellent

Coffee is a excellent repellent natural, just like ash or sand, without harming animals.


In your garden, place coffee grounds at the base of plants infested with aphids or attacked by slugs. In the same spirit, you can also mix water and coffee grounds and spray your plants with the mixture.


Have ants invaded your home? Mix coffee grounds with lemon juice and create a barrier by drawing a line of the mixture, perhaps on a windowsill. Ants won't cross this line!
