Back in 2015, a young tree was planted in front of my house. It was an Armstrong Maple, and was a replacement for an ash tree that had been killed by an infestation of the nasty Emerald Ash Borer. I was excited about my beautiful new tree. I called him Mr. Armstrong, and and wrote about him here.
But all is not well with Mr. Armstrong. For the last couple of years, I noticed that the main leader branch at the top of the tree had no buds or leaves. Last summer a tree specialist cut off the main spike, and the tree seemed to recover. However, the main trunk shows either insect damage or some kind of disease, and there's loads of grey and yellow lichen growing on the bark.small shelf bracket fungus has started to grow, a sure sign of something that shouldn't be happening to a healthy tree.
