Chlorosis is a nutrient deficiency in the soil. The most common sign of chlorosis is a yellowing of the leaves.

What is It?

Chlorosis is a nutrient deficiency of iron or manganese. The lack of these nutrients compromises the tree's ability to produce chlorophyll.

Affected Plants:

Pin oaks and river birch tend to be the most susceptible species of tree. Problems in the pH balance of the soil is most often the cause of chlorosis so any acid loving plant can be affected by chlorosis.

How to Identify:

Chlorosis can be identified by looking at the leaves of a tree. The leaves of a tree with chlorosis will turn a lime green or yellow color with possible browning on the leaf edges.
