We met the Oak Tree in 1981 when we moved in. :) It had a sister tree on the right that was removed before we moved it. This tree at that time had no branches on the right side . It filled out as you see on the right over time. It was hit by lighting in 2000 and blew some of the bark off the tree. The wound healed well. We have watched t old oak trees in the neighborhood dying slowly and removed over the last 10 years Maybe 4 years ago, the crown in ours started dying out. We had some large branches removed a couple of years ago mid winter as it was growing close to neighbor's home. Branches are starting to fall into the yard on Windy days and the general smaller 3-4 foot Branches during the summer. Concern. How do we move forward with this beautiful dying tree. with the crown dying do we take the whole tree down or cut side branches . We know it will be expensive and we are pretty sure it is still solid in the ground, Would like imput from you for time line, strategy and references for those that Could be helpful for us if cutting it down or trimming is necessary. The tree is by landscaping and buildings and the neighbors home. We value your advice on all levels . We release we must act in a timely because of the weather and pruning windows of opportunity. Thank you for your time
