onion peel

Incredible to say, right? However, in the peel of the onion lies a powerful repellent that will keep fungi and other insects at bay. We take the onion and only remove the skin, without also removing the vegetable part. Let it soak in boiling water for at least two hours. Then we transfer everything to a container with a spray bottle after filtering it and our fungicide liquid for our plants is ready. We can use it for any plant we have at home without distinction.
