Root-Zone is a humectant formulation that is drenched into the root system. This conditions the plant to produce additional amounts of abscisic acid (ABA) thus closing the stomata and reducing its own transpiration rate naturally. One application keeps most containerized plants saleable for up to three weeks without additional watering. Root-Zone anti-transpirant is most effective on all types of containerized plants. Use for shipping, display, transplanting, extreme weather conditions or water shortages.
