[CANUFNET] Question to mailing list members

[Naomi Zurcher]

Completely agreed. If trees are creating sprouts, that’s usually out of necessity and a response to some inadequacy or problem. It is critical that we observe how trees manage themselves and incorporate that into our practice.

Removing sprouts is an aesthetic  driven practice, not much good to the tree as far as I can see. And could be a stress that attracts the beetles as previously mentioned here.

We have been alerted to this by a university researcher who claims that leaving this growth on elms can leave them vulnerable to Dutch Elm disease. I have never heard of this and want to know if anyone has information to support it.
