Pear trees tend to grow straight up. It will be a continual battle to
get growth in the direction you want. You should use spreaders and
selective pruning to encourage side growth.

At present I would employ additional thinning and some selective pruning
to control the vertical growth.

Have you pruned them at all during their dormant season? If not, find a
guide at your library/bookstone or on the internet on pruning and care of
fruit trees. I can't think of a good one off the top of my head, but
perhaps someone else can.
