Dutch Elm pruning/trimming when is too late
I have a healthy dutch elm in my yard, but it needs to be trimmed back. The earliest my tree company can perform the work is the week of May 6th, 2019 I'm concerned this is too late in the season and may cause tree to be susceptible to beetles or other diseases. Should I delay the trimming until next winter?
We recommend waiting until fall into winter for the trimming to be done. October, November and December are best.
This misses the life cycle of the European Elm bark beetle, which vectors Dutch Elm Disease.
