Leaves turning brown - cherry tree

Asked August 15, 2016, 12:36 PM EDT

Over the last couple weeks, the leaves on both my (meteor) cherry trees have become yellow or even brown. It started with a few leaves, but now has spread to the majority. A nearby Serviceberry tree lost leaves that turned yellow then red and dropped off a month ago, but only in about 3 small branches and now in general that tree is fine. Also plants nearby are affected - specifically the wisteria is all yellow (and has been for a while now), as well as the astilbe and the snow on the mountain. It all seems to be along one part of the garden. Some plants are fine - seems to be by species. I enclose a photo.

Thank you for the question. Unfortunately, a diagnosis of such a wide-spread problem can't be made based on the photos. When so many different plant varieties are affected, we tend to think of non-biotic causes like herbicide injury, weather conditions and cultural problems. We can make some suggestions but there is no substitute to having a certified arborist come to your yard and take a look. The cherry tree leaves look like they might have a problem with iron chlorosis because of the green veins on the leaves and yellowing between them. There is no easy fix.

Here is our publication on growing cherry trees in Minnesota. You might discover some clues when you read about how to best maintain the health and productivity of this tree.

A soil test is in order to help rule out soil fertility issues: http://soiltest.cfans.umn.edu/

Good luck and thank you for contacting Extension.
