I see hard maples (sugar maples or something like them) usually juvenile tree dying all over. They have these white spots all over (fungus). Then whole branches dead, eventually killing whole tree. Please advise.
Here's a couple examples from my parent yard. Sorry for the horrible structure as I just started learning how to prune trees correctly in the last couple years!
This one is half way up the canopy. Seems to be more spots up higher.
Maybe this is elementary for you guys but I'm just learning plant health. Maybe you can recommend some good books so I can stop boring you!
Thanks in advance.
