Maple trunk split

Asked November 6, 2019, 11:41 AM EST

Some time in the past several days, the trunk of a young maple in my yard split nearly in half, starting right at the main Y of the trunk. Is there anything I can do to try to save this tree? It just gave its most beautiful seasonal fireworks display yet. :’-(

Unfortunately there is nothing that you can do to help a tree with a vertical split in the trunk. Shear cracks are vertical cracks that run completely through the trunk and separate it into two halves. When the tree moves in the wind, one half of the stem slides over the other, elongating the crack. Eventually the enlarging crack will cause the two halves of the stem to shear apart. The bark wound also increase the chances that the tree will develop insect and disease problems. The tree at higher risk of failure.This site explains how to hire a professional certified arborist.
