Neem oil and neem cake are beneficial for nurseries and ornamental shrubs because they provide natural pest control and enrich the soil. Neem oil effectively repels and kills common pests like aphids, mites, and scales without harming beneficial insects. Neem cake, a byproduct of neem oil extraction, acts as a natural fertilizer, improving soil health by adding nutrients and organic matter. Additionally, it has antifungal properties and helps in managing soil-borne pests, promoting healthier and more resilient plants.
