Pin Oak Decline
Good Afternoon, I was referred to the extension by Mr. Orndorff regarding a Pin Oak I have in my yard that has been having issues. We had a couple branches fall 2015 Spring and so we hired a tree company to prune off the dead branches. Recently, it dropped 2 more branches, within 2 weeks apart and I noticed another cracked but is wedged between 2 branches. one of the branches that broke off had some dead but some live leaves and it also had a black ring on the snapped end. I have had some companies say that it should be cut down and some say it just needs to be pruned back. I am unsure what to do and was hoping to get someone who is reputable and that can make an educated decision by assessing our tree

There could be several reasons for branch dieback and decline such as drought, poor soil drainage, changes in soil grade, mechanical damage to trunk, etc. See our publication on these types of problems. http://extension.umd.edu/sites/default/files/_images/programs/hgic/Publications/HG86%20Common%20Abio.. . When stressed by the above, the tree can be susceptible to possible insect and disease issues.
We recommend that you contact several certified arborists for an onsite diagnosis regarding the health of your tree and the best way to proceed. http://www.treesaregood.org/
