My Black Gold was off to a great start, but now I am concerned about it dying.
Some people have suggested Canker, some borers.
But I don’t have confidence as to what it is or what to do.
I have pressed on the bark on the dark patches. It is rather soft there, and feels as though there is some fluid behind.
But I don’t know if I should try to shoot some insecticide behind the bark, or just do nothing, or push pins in it here and there trying to kill a worm.
These photos were just taken and may give you more insight.
Thank you!
PS I am in zone 6b of Central Kentucky. The only thing I can think of that I may have done was give it too much fertilizer. But I really didn’t give it that much. That was in the middle of March.
