cutting back river birch tree to trunks
I have a extremely large river birch with three trunks that is about 20+ years old planted 10 ft from my house and patio. One of the trunks is leaning against our chimney and the branches are spread out over a large area of our roof. I was wondering if I can have each trunk cut back to about 12 - 15 feet......which would leave only a couple of branches on each trunk. Would it survive and put out new branches from the trunks only. I was considering having it removed, but if I could reduce it to about 1/2 of its current size I might keep it. Thanks for any help or suggestions.
