We had a dead tree fall onto one of our Hawthorne trees last night and take out about 1/4-1/3 of its larger branches. We have 6 of these Hawthornes in a row and would have to lose this one. Replacing it would be costly as we have had these for about 12 years now. Do any of you have advice on how to save the branches that have not completely broken off and also to repair any other damage to this tree? Thank you.
