Iron deficiency (iron chlorosis) affects many desirable landscape and crop plants grown in Utah. The primary symptom of iron deficiency is interveinal chlorosis, the development of a bright yellow leaf with a network of dark green veins. In severe cases, the entire leaf turns yellow or white and the outer edges may scorch and turn brown as the plant cells die.
