Greenspire Littleleaf linden tree dying

Asked May 29, 2017, 10:02 PM EDT

We have two Greenspire littleleaf linden trees that are 28 years old. One looks fine and the other one is dying. It looks like about 1/3 of the tree on the west side is dead and the rest of the tree has much less foliage than is normal and the leaves are lighter green. We thought last year this tree looked a little lighter green in color but didn't think much of it until this year when so little of it leafed out. Any suggestions as to how we can save our tree? I don't see any borers, but am not sure what exactly to look for and where to look.The third picture I have sent shows part of the dying tree with the healthy linden in the background. Thanks.

There is usually no single reason for tree decline. Often, tree decline is due to a combination of factors. Unfortunately, once a tree begins to decline, it is usually irreversible. The tree will likely continue to decline and die within a few years.

If you wish, a plant specimen can be sent to the ISU Plant and Insect Diagnostic Clinic. The clinic may be able to determine if insects or disease are factors in the linden's decline.
