Place the onion peels in a glass container and add half a liter of boiled water, allowing it to cool. In a separate container, infuse five tablespoons of rice with a liter of room temperature water, filtering the resulting rice water. Combine the rice water with the onion peel solution, creating a nutrient-rich mixture for orchid fertilization.

Before application, dampen the orchid leaves and soil, allowing thirty minutes for root readiness indicated by a green hue. Apply the fertilizer by gently swabbing the leaves with a cotton pad soaked in the solution, enhancing leaf resilience against pests and providing vital vitamins. Alternatively, spray the solution under and over the leaves once or twice a month, combating fungi and parasites effectively. Pouring the solution into the vase soil further stimulates rapid growth, strengthening both leaves and flowers, ensuring a flourishing orchid display throughout the year.
