I live in Fruita and I planted a chitalpa tree two years ago.  Last summer the top of it had died, so I cut it down to where it was still alive, but it sent shoots out of the lower trunk and the ground around the tree.  This made it look like a very large bush.  This year I'd like to trim it so that it will look like a tree again.  Do I just cut off the extra trunks with a saw?  Will the growth go into the trunk I leave?  It still looks quite dead, but it did last year at this time as well.
