Dyna-Gro Brand 100% Pure Neem Oil is derived from the seed of the Neem Tree found in Eastern India and Burma. Among its many uses, Neem oil may be used as a natural pesticide and fungicide for plant care. Neem Oil leaves a natural shine on leaves without clogging stomata that leaves need to take in carbon dioxide and release oxygen and water vapor essential to the basic functioning of the photosynthesis process. Many of the glossy leaf polishes, which give an unnatural appearance to leaves, actually interfere with these natural transpiration processes. |
