The yellowed onion scales that usually end up in the trash are actually a powerful growth and bloom stimulator for roses. An infusion of husks not only saturates the plant with nutrients, but also effectively protects it from common diseases, acting as a natural fungicide and immunomodulator.
Hidden in onion peels is a whole range of useful substances: vitamins, natural antiseptics (phytoncides), antioxidants and minerals. All together they act on the rose as a powerful stimulant: they awaken new buds, strengthen the roots and help the plant more easily endure stress – be it heat, cold or lack of nutrition. Phytoncides also work as a natural defense against fungi that cause powdery mildew and black spotting.
To prepare the elixir, a handful (about 50 g) of clean onion peels is poured with 2 liters of warm water. The mixture is brought to a boil over low heat, then left covered for at least 4-6 hours until completely cooled. The resulting concentrated infusion is filtered.
For root feeding, 500 ml of infusion is diluted in 5 liters of clean, settled water. Under each rose bush, pour 1-1.5 liters of the resulting solution over pre-moistened soil. For foliar treatment (spraying), the infusion is used undiluted, thoroughly wetting the leaves on both sides. The procedure is carried out early in the morning or in the evening.
Already 3-4 days after spraying, the leaf blades become healthier and signs of chlorosis disappear. After 7-10 days, rose bushes are actively forming new buds, flowering becomes more luxuriant and longer, and the color of the petals becomes more intense.
