I planted a tulip poplar about 8 years ago. The tree has grown really
fast - and by the fall of 2001 it was topping 30 feet tall. Unfortunately,
the top 10 feet or so broke off in a strong thunderstorm in September, 2001.
A few weeks later I pruned the main trunk back about 2 more feet, to get a
clean break. I also removed a few of the branches that broke off when the
top of the tree came down. FWIW, the trunk was about 4 inches thick at the
break.

Last summer the tree grew with it's usual vigor, and it also put out lots of
flowers. When the leaves fell in the fall it revealed that there are many
new vertical growing branches. A couple are growning off the main trunk
near the break, the 2 or 3 largest are growing off larger branches, but at
the base of those branches near the trunk of the tree, and easily another 10
or 12 small shoots are growing straight up from further out on the large
branches or from smaller branches.

Here's what I'm wondering - I would like the tree to grow tall. Would it be
best to prune back all but one or two of these vertical growing branches to
encourage upward growth? I'm worried that if I let thing go without
pruning, the tree will just bush out at break and never really get back into
the upward growth pattern.

Thanks in advance -
