I have a mature maple tree in my back yard. Last week one of the upper tru nks split and came down. It was on a very rainy day and the tree had recen tly leafed out. The tree appears to be very healthy with new growth on all branches. The split occurred on one of the main trunks about 20 feet abov e ground.
As I was looking closely at the tree to see if there were any obvious poten tial future failures, I noticed that at the end of one of the branches off of the main trunk, several new growths/shoots were more than two feet long. All over the rest of the tree the new growths were about 4-6 inches long. There no long growths anywhere else that I could see.
Anyone here have any ideas what causes this, and do the fast growths lead t o future weaknesses in those branches? Any suggested web sites for further reading?
