Onion peels: an effective repellent
It may seem surprising, but onion peels contain a potent repellent that will keep away fungi and harmful insects. To prepare a natural fungicide, simply remove the onion peel, making sure to leave the edible part intact. Soak the peel in boiling water for at least two hours, then strain the liquid. Transfer it to a sprayer, and you’ll have a ready-to-use fungicidal liquid for all your indoor plants.
