Dyna-Gro Neem Oil Leaf Polish - 1 Quart ventilation The SAM 400® patented UV-CDescription 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.
