How to recognize and treat chlorosis

Chlorosis, a chlorophyll deficiency that results in the yellowing of normally green leaves, is a relatively common disease. It can affect many kinds of plants including roses, vines, rhododendrons, and hydrangeas. Here’s an overview.

Causes
Chlorosis can be a sign that your soil is nutrient deficient. If your plants are deprived of chlorophyll, the leaves are likely to turn yellow, become dry, and fall off. The most common soil deficiency is iron. However, chlorosis can also be caused by a lack of magnesium or potassium.

Treatment
The most effective way to prevent and treat chlorosis is to do a soil test. This will let you know if your soil lacks nutrients or contains too much calcium, which can prevent your plants from absorbing vitamins and minerals. Soil that’s too wet or dry can have the same effect. Once you understand the problem, you can make the appropriate adjustments.
