Q: One of my large flowering cherry trees split down the middle. Can I save it by putting a strap around the tree and pulling it back together?

A: Eventually the tree will fail but you might be able to get a few more years of life out of it by having steel cable installed between the two trunks several feet above the split. This should be done by a certified arborist who knows how to use the correct hardware.

The two halves of the trunk will not graft together.

If you do nothing, I wouldn’t expect the tree to last another year.
