Numerous experts recommend combining these two substances to promote plant growth, clean the home or for personal care.
In times when sustainability and household savings have become priorities, more and more people are turning to natural solutions to improve their quality of life. One combination that has sparked the interest of experts and gardening enthusiasts is the mixture of banana peel and vinegar, a simple formula that offers multiple benefits for both the home and environmental health.
According to the specialised website Tua Saúde, banana peel is much more than just organic waste. It contains essential minerals such as potassium, magnesium, phosphorus and calcium, which not only strengthen the human muscular system but are also essential for plant development. In addition, they have properties that help regulate cholesterol, improve digestion and care for the skin, making them a valuable resource that often ends up unfairly in the rubbish.
Vinegar, especially white or apple cider vinegar, provides acetic acid, a compound that accelerates the decomposition of organic matter and facilitates the release of nutrients. It also acts as a soil pH regulator, which promotes the growth of plant species that require more acidic environments. In the domestic sphere, it is credited with antioxidant and anti-inflammatory properties and even benefits for hair and cardiovascular health.
The preparation of this homemade fertiliser is as accessible as it is effective. Simply collect several banana peels in a clean container, cover them with vinegar and let the mixture sit for 48 hours. After that time, it is recommended to dilute the liquid in equal proportions with water before applying it directly to the soil. This step is crucial to prevent the acidity of the vinegar from damaging the roots of the plants.
Experts cited by elEconomista say that this mixture can be used weekly in gardens, pots or urban vegetable gardens, offering an environmentally friendly alternative to chemical fertilisers. In addition to nourishing the substrate, it improves flowering and stimulates root growth, resulting in stronger and healthier plants.
Beyond gardening, this combination can also be used as a natural cleaner or odour neutraliser, reinforcing its multifunctional nature. In a context where every gesture counts towards reducing environmental impact, reusing everyday ingredients such as bananas and vinegar is a smart and responsible practice.
Thus, what was once considered simple waste is now revealed as a powerful ally in the search for a more conscious lifestyle connected to nature. Who would have thought that the secret to a greener garden and a cleaner home lay in the most common fruit in the kitchen?
