Should I replace this damaged tree or wait
We have an amur maackia that we planted three years ago. It's been a lovely tree. Some contractors installing cable boxes on the lot next to ours tore a main limb off it. As you can see the wound is deep, and my pictures don't show how lopsided it now is- before this it had a great shape.
I talked to the contractor and agreed to wait and see if the tree survives. But a knowledgeable neighbor told me it will never properly heal or correct its now lopsided shape. So I am thinking of insisting the contractor replace the tree now, rather than wait and lose more years of growth. He didn't seem too happy when I contacted him, and he launched into a story about some other tree they damaged that grew back just fine.
So for anyone who knows trees- do you agree I should stick to my guns and have them replace the tree? I had been faithfully watering it 3 summers now- I really don't want to wait two more and then figure out the tree is done for and have to start over. But I don't know enough about trees to confidently argue my point with the contractor, so some input would be greatly appreciated.
