Neem oil and neem cake are excellent for fruit trees because they offer natural pest control and enhance soil health. Neem oil helps protect fruit trees from pests like aphids, caterpillars, and mites without leaving harmful residues, making it safe for edible crops. Neem cake, rich in nutrients, improves soil fertility and structure while also repelling soil-borne pests and fungi. Together, they promote healthier fruit growth and higher yields, reducing the need for chemical treatments.
