“Umbrella Tree” having some issues.

Asked July 9, 2020, 10:13 PM EDT

Our “umbrella tree” (not sure of the species) has some browning of leaves as noted in the attached pictures. I was hoping for a recommendation of what if any treatments might be available.

Multnomah County Oregon

Thank you for the images.

Your Camperdown Elm has leafminers. They are periodic pests and, as a result, seldom adversely affect the tree's health. No sprays are helpful because the pests are between the upper and lower layers of the leaves.

However, promptly raking and destroying fallen leaves may help decrease the pests' population during subsequent years.
