[CANUFNET] Elms and breakage

[Alison Bond via CANUFNET]

All:

At a conference in Quebec City I learned that much of the areas around the parliament buildings were being planted with Accolade Elm with good success.  After that conference we started incorporating elms into our street tree planting plans.  Accolade wasn't always available so there were often substitutions (Valley Forge, Princeton, Pioneer, Triumph.)

I have recently noticed that some of the elms (when reaching about 15.0 cm dbh) are starting to break apart and large branches are failing.  Many of these elms are vigorous growers and municipalities haven't been able to keep up with pruning to keep the form strong.

Has anyone else noticed this predisposition to breakage?  

Thanks.
Alison
