Oak Tree

Asked July 29, 2019, 2:31 PM EDT

We have an Oak tree that did the same thing last year and is starting to do it again this year. What is happening is that it buds in the spring and looks good but now it is starting to have branches at the bottom start to die and turn brown. It always starts with the bottom branches.

If you are saying this is the same tree that has experienced the same type of dieback two years in a row. I can see oaks in the Red Oak group. They appear very yellow which is a sign of stress that can be caused by a number of issues. This tree is also sprouting from the stem quite heavily. Tree attacked internally by borer insects, cut off the flow or reduce the flow of water going up the tree and this causes upper part of tree to die back while energy pushes out new growth along the stem. Borers usually are drawn to weak trees. I see sandy type of soil in this picture. There are many factors that can weaken a tree, such as nutrient deficiencies or drought. The summers of 2016 and 2017 had severe droughts across parts of Michigan. This year we had extreme wet conditions. It is hard to say where this started. I would want to get an expert out to look at these trees especially for borers. The two lined chestnut borer is a common problem on oak trees.
