What I Look for Before Buying
When I shop for neem oil, I always check a few important things. I prefer products that are clearly labeled for plant use, and I make sure the bottle explains how to dilute it properly. I also look for cold-pressed, pure neem oil because I find that it usually gives me better results than heavily processed options.
