This brings up another question....

I have this feeling there is some sort of borer in the tree because I
see fine sawdust at the base of one of the trunks. I cannot find a
hole anyplace but there has to be if there is sawdust.

if I chop all three trunks down tot he ground, do y ou think I could
get a few suckers to grow? Would those suckers be decent looking
trees? Or am I just having a pipe dream??
