Iron & Short Stop Tree Injections #878895
Asked July 26, 2024, 12:28 PM EDT
We moved to our house in Oakland County over six months ago and are having all the trees trimmed on our property. We have a maple tree that's leaves are yellowing and showing signs of chlorosis. An arborist recommended a iron injection. Will the iron injection address the chlorosis? Or could this be another issue?
We also have a Norwegian red maple next to our garage and it looks like a few years ago they put in new concrete for the driveway. Some of the branches do not have leaves on the ends. The arborist recommended an injection of Short Stop to help the tree focus on its root health and not on growing new branches/leaves. Will the Short Stop make sure the tree will focus on its roots? I want to understand if this is a recommend practice to support trees that likely had some root damage.

Hi Bridget,
The yellowing leaves on the maple does look like chlorosis, and an iron injection is one way to correct the issue. However, the main issue that causes chlorosis is the soil chemistry, which should also be addressed while the injection improves the tree's health. Below is a link to an article that describes several ways to address the soil to limit chlorotic events in the future.

The "Short Stop" injections involve a growth regulator that will inhibit above ground growth so that the tree can focus on the roots. So, it is something that is done to promote tree health over time.
I hope this helps. Please feel free to reach out with any questions.
Thank you,
