Interveinal Chlorosis

Interveinal chlorosis is a yellowing of the leaves between the veins with the veins remaining green. In plants with strap-like leaves such as the daylily this results in a striped effect. While there are several possible causes, this symptom frequently indicates a nutritional imbalance. The accompanying image illustrates a daylily exhibiting interveinal chlorosis. In this particular case, leaf tissue analysis indicated the cause was probably manganese deficiency induced by high soil pH.
