Few days ago massive amount of foliage was removed from the tree. Honestly, bit too late. A lot of inner foliage in the crown was yellow and weak already. I hope I will not lose too many branches. Fact is, I barely manage to do all necessary maintenance on trees during the season. More developed trees ar, more time you need for all the pruning, defoliation, wiring. With same amount of trees over the years, more and more work needs to be done from season to season.
You can check this post from April were tree is after some editing and without foliage.
