Botanicare’s beneficial root inoculate, ZHO, has a fresh, new look and is easier to use. ZHO is a unique and proprietary blend of beneficial Endomycorrhizal fungi, Trichoderma fungi and highly available L-Glycine amino acids. ZHO promotes rapid new root growth and improves the plants’ ability to uptake water and nutrients. ZHO was specifically formulated for fruit bearing and heavy flowering plant types. We chose only Endomycorrhizal species for ZHO due to their ability and preference for colonizing mainly soft stemmed plant types. This means you get more of what works, and less of what doesn’t.
