What is Neem Cake Powder?
Neem cake powder is a natural organic fertilizer and pesticide made from neem seeds after extracting neem oil. This eco-friendly byproduct is widely used by organic farmers and home gardeners across India to improve soil health, protect plants from pests, and boost crop yields naturally without harmful chemicals.
