How to Prevent Iron Chlorosis

When it comes to iron chlorosis, preventing it is always going to be better than curing it. The best way to do that is to ensure your tree has a sufficient supply of iron throughout the year. A common way to do that is to introduce iron-rich fertilizer to your soil. This type of fertilizer will deliver iron, as well as a variety of other essential nutrients, to ensure your tree has everything that it needs to thrive.

To ensure that the fertilizer you are using is most effective, it should be delivered to your trees via trunk injection. In doing so, the iron will quickly travel from the base of your tree upward and to your tree’s extremities. For best results, you should schedule fertilizer treatments in both the spring and fall.

Fertilization in the spring will help stimulate growth and fertilization in the fall will help your trees stay healthy through the winter season.
