Our Birch tree was getting too high about 30 ft, and has too many branches blocking view in the back garden. So I went up on a ladder and sawed it into half. The trunk fell onto the ground leaving half of the trunk, but while doing so, I also took off many branches which looked rotting, twisting ..etc Now the tree is about half the height, but only one or two branches left with some leaves. It still haven't dropped leaves or wilted away. But I was just wondering if it will revive, and grow again come next spring.
