VitaLink Foliar is a calcium-rich foliar feed, proven to help produce stronger and healthier plants. Plants require a large amount of calcium for the development of cell walls which keep the plants strong and healthy by increasing their resistance to pests, disease and drought. VitaLink Foliar is sprayed on the leaves of the plant to ensure that calcium reaches areas where it is needed, as calcium has poor mobility within plants. It also contains a wetting agent to improve absorption.
