Onion skin fertilizer promotes the formation and growth of flower nodes. To prepare the broth, you will need a medium-sized onion, lightly soaked in its skin, and a glass of water. Cover the skin with water, boil for ten minutes, let it rest over low heat for one to two hours, and then strain. Dilute the concentrate with room-temperature water until light and apply to the flowers.
Onion skins are also rich in various vitamins, potassium, phosphorus, and manganese. They contain carotene, an essential element that strengthens the plant’s immune system, allowing it to fight off a variety of bacterial and fungal diseases and thrive undisturbed.
