Citrus trees utilize very little or no chlorine in their nutrition processes. They do, however, tend to accumulate chlorine in certain tissues. When such accumulations become excessive, they may cause the tissue to burn as in leaf tips and margins. In addition, the leaf size may be reduced and a fading may take place in the chlorophyll or green coloring matter of the leaves.
