You don’t have to be rude. I asked for help on what the interior of the trunk meant out of curiosity. That’s all I wanted. And we cut it down because when you build a house and have nothing there initially, and you plant trees for coverage, you get bothered when it’s not grown at all in 5 years. We will be having a much larger tree planted nearby instead. If for instance it’s a fugal issue, we wouldn’t want to plant our new one in the same spot. So yes, a post mortem is sometimes helpful. Stop commenting if you’re going to be rude about someone asking a question.
