The Indian neem tree has long been revered as a source of safe, natural pest control. Organica uses a cold-pressed neem oil that is then put through a unique saponification process (it's made into a soap). The end result is an insecticidal/fungicidal soap derived entirely from a natural source. Organica's K+Neem controls a wide range of mites and insect pests and is also effective against powdery mildew disease. It's the natural choice for vegetables, herbs, trees, shrubs, roses, houseplants and turf.
