I have a customer that has a Magnolia of 2inch caliper that looks dead. Tree service had stated it was two wet. I was present when he made this conclusion. He did not seem confident. Yes the the ground was wet. Yes the bark had split verically on the trunk. Here is the question. Tree looks totally dead except lots of new growth at the base. Will the old growth Bud out again in the future? Should I just dig it out and start all over planting a little higher? Thank You in advance for any advice.
