Dutch Elm Brown Leaf Spots and Pine Trees Dying

Asked June 12, 2018, 2:46 PM EDT

Hi, We have 2 issues: 1) Our dutch elm is over 60 years old. The past several years we have had brown (dead) spots on the leaves. Where the spots are brown, it looks paper thin and almost see through. The spots appear to go all the way to the top of the tree. Will we loose this tree? What can we do to prevent this from happening every year? Who is a good company if needed? 2) We have a row of long needled pine trees around the boarder of our property. One died and we cut it down, the next year another died and we cut it down, this year another is dying. They are all next to each other (one after another). We don't know what to do or who we should contact. We need your help....please. =) Please let us know if you need pictures. Thank you. Paul and Brenda Schiller

Foresters and certified arborists have the training and experience needed to address the problems you have described.

University of Minnesota Extension does not recommend or vouch for the reliability of tree care professionals but you can use the information in the following bulletin to find the help you need.

How to hire a professional arborist to help care for your landscape trees

Although leaf spots can be unsightly, they usually don't affect tree health.

Based on your description, we suspect that the pines may have been damaged by borers. A tree care professional will be able to determine whether borers are present and otherwise recommend what can be done to protect the trees that remain.
