Don't throw away your coffee grounds, reuse them!

It is an excellent natural fertilizer
"Coffee grounds are good for plants and the vegetable garden, but in small quantities otherwise the soil will become too acidic and nothing will grow…"
explains Julie Jacqmain, Production Manager at Permafungi.
Anaïs Levoir, Bio-Engineer at Worms explains: "Coffee grounds may inhibit the growth of certain 'competitor' plants"
Because the coffee plant, the coffee seed produces a chlorogenic acid. It is a biological phenomenon called allelopathy that influences the germination, growth, survival and reproduction of other organisms. But on the other hand, once composted, about 6 months, it is a very rich fertilizer. But do not exceed the proportion of 10 kg of coffee grounds nwe compost per m² of soil."
One solution would be in autumn, at the end of the season, to mix coffee grounds with the soil to prepare for the following season. Some plants are really boosted by coffee grounds like roses and hydrangeas. On the other hand, the tomato plants do not appreciate it too much… Always put composted coffee grounds on the ground. If you add coffee grounds alone, it must be done in small quantities to avoid allelopathic effects.
Coffee grounds are also a good compostable material.
Anaïs Levoir, Bio-Engineer at Worms believes that coffee grounds are very interesting for compost: " because it is rich in nitrogen". It also contains a little bit of carbon but it is negligible compared to the carbonaceous materials that we put in the compost.
But beware, it's like on your plate you have to vary the intake. " If you have a vermicomposter at home, throw your grounds in it. Il will be digested by the worms like the rest organic matter from the compost. "
But don't overdo it, warns Anaïs, otherwise it could upset the balance of your compost. It is better not to exceed one-fifth in proportion. We can put too less, of course!
Julie Jacqmain, Production Manager at Permafungi, confirms: "You can even put the coffee filters in natural paper if they have not been treated with chemicals (these are often the bleached ones) and trichoderma,has green mold that grows quickly on coffee grounds will also boost compost and decomposition."
You would think that its rough appearance could protect your plants from crawling pests like snails or slugs by scattering coffee grounds all around. But no ! Julie Jacqmain, Bio Engineer and Production Manager at Permafungi "I've already tested coffee grounds to repel slugs and snails in my garden and it changes absolutely nothing.".
Blue your Hydrangea flowers.
"Add coffee grounds to the soil at the base of the hydrangeas to make them change color. Coffee grounds increase the acidity of the soil and will turn the plants blue." But again with parsimony underlines Anaïs Levoir.
