Q.should i take down my maple tree?
Recently, one huge branch broke off and we removed it. The tree has been pruned in a way that all of the main branches are on one side of the tree. Also, when I removed the branch, there was a dark red ring within the wood. Does this mean the tree has some sort of disease? It looked like the branch rotted and then broke away. The tree is about 45 ft tall and is about 40 years old.
The safety and health of a tree is best determined by a professional arborist.
Perhaps the tree could be pruned to a more eye appealing shape.
The dark red ring you mention may be nothing more than a normal growth ring.
