Chlorosis in Plants

Chelate compounds used in very small quantities have been found effective in controlling lime induced chlorosis in plants. Chlorosis, the loss of green coloring matter in leaves, is usually called a nutritional disease, or physiological disorder caused by a deficiency or excess of one or several minor elements, such as iron, zinc, manganese, copper or magnesium. Other factors which contribute to chlorosis, are poor soil aeration, excess watering, poor drainage and high concentrations of calcium or sodium bicarbonates in the soil.

Most chlorosis is caused by a lack of available iron and can generally be corrected by working iron chelates into the soil around the chlorotic plant. Suggested application rates range from two to three teaspoonful for small shrubs and roses to 1/2 to one pound for large shrubs and trees.
