It does not appear to have one dominant leader, and the homeowner is wondering if the many crowded branches growing vertically are weak attachments. The homeowner also wonders if by thinning the crown in particular, the verticle branches growing upward, would reduce wind drag and make the tree less likely to fail. What do you think?

Often arborists in the field will sample the soil to better understand the situation, but what about sampling the tree? The sample is typically extracted from the crown, where growth is active, using either a leaf or small twig about one inch long, which is then sent to the lab. Arborists can then compare and contrast what is in the soil vs. the tree. Let us know if you have used tree sampling for chemical analysis in your work.  Click on the headline to leave a comment.
