Trees are known for their abundant leaves and natural beauty. But they are also vulnerable to developing illnesses without proper tree care and maintenance. Iron chlorosis is a condition that can afflict the foliage. It’s important to recognize the signs of this condition so that you can act promptly. Here’s what you should know.

A Guide to Iron Chlorosis

What is iron chlorosis?

All plants need iron to produce chlorophyll, which is vital to the photosynthesis process. When a tree becomes deficient in this micronutrient, it leads to iron chlorosis. As a result, chlorophyll production slows down, which can significantly impact the health, appearance, and longevity of the tree.

What are the symptoms?

tree careChanges in leaf color clearly indicate that there's a problem. They’ll turn yellow and develop contrasting green veins. When the deficiency becomes severe, the leaves may take on a completely white or yellow appearance. Eventually, the leaves’ cells fail entirely, leading them to take on a scorched look and a brown color. 

What causes this?

It’s not always easy for tree care providers to determine the precise cause of an iron deficiency. Many factors can affect iron’s presence, but often the issue is related to the composition of the soil.

Chlorosis concerns are often discovered in alkaline soil, or that with a pH balance over 7.0. While the soil itself may be iron-rich, the elevated pH level stimulates a reaction that prevents iron from feeding the roots. Low levels of oxygen in the soil can also affect iron availability to the tree, especially if the soil becomes compacted.

How is iron chlorosis treated?

Have a tree care provider assess the severity of chlorosis as soon as you detect a problem with the leaves. Your technician will inject iron directly into the tree to resolve the symptoms. If caught early enough, the leaves should return to their standard green color.

You can also practice preventative techniques to avoid this problem. Regular aeration, for example, can help the soil breathe and minimize issues related to low oxygen levels. You can also ask your technician about adjusting the soil’s pH balance to make it more iron-friendly.
