Canoe birch tree
We have a 22 year old canoe birch tree in our south facing yard. It is as tall as our two storey home. It has developed vertical cracks on both the north and south sides of the tree and the cracks are several feet in length. It has one thick trunk and 5 large limbs. We have also noticed a bore hole near the base of the tree. We have had a few years where some insect has destroyed the leaves but others where it has been fine with an insecticide applied just before the leaves appear. We are wondering if this tree needs to come down before a wind storm helps it fall down as it is close to our home and deck. Any thoughts? Should we wait until spring to see how it is? D.

Yikes! Unfortunately, this tree appears to be starting to form a dangerous situation. From insect damage, and likely disease from the insects, the tree is looking like it might give up and fall. I believe it would be best to take it down if it start to get any worse than that.
