Iron is a mineral essential for plants to make chlorophyll, in turn needed for photosynthesis. Chlorophyll is also broken down in these leaves, and the leaves turn yellow and eventually fall off. It results from failure of chlorophyll to develop because of infection by a virus; lack of an essential mineral or oxygen; injury from alkali, fertilizer, air pollution, or cold; insect, mite, or nematode feeding; gas main leaks; compaction or change in soil level; and stem or root rot. Iron is important for chlorophyll synthesis in plants, so when it is deficient, leaves cannot make chlorophyll, resulting in a yellow appearance. And it becomes a pity when they start to get sick.

Both methods involve drilling holes in the trunk - the number of holes is based on trunk diameter. It occurs when the formation of chlorophyll in the leaves is disturbed. Unfortunately, they can not tell about their problems, but we are almost always able to understand their appearance, what happened.

In many crops nitrogen related chlorosis begins from the old lower leaves, the leaf tip and midrib turn yellow but the leaf edges stay green. Iron chlorosis starts on the younger or terminal leaves and later works inward to the older leaves. If left untreated, interveinal chlorosis can be detrimental to the plant.
