[CANUFNET] Pioneer Homestead and Accolade Elms, concerns.

[Hennessy, John]

Hello All. Thank you for the consideration. In Brampton it has come to our attention that many of our young Elms(10-15cm dbh) are struggling to fill their canopies this spring. One issue is the tips of branches have leafed out, however the interior of tree has not produced leaves. Further to this, a second issue would be the apparent black mold ( Wetwood ) on pedestals and in bowl region on other trees. Are others having similar issues? Both of these issues are consistent throughout the city. To date it would appear the Accolade Elm is most affected, with the pioneer and homestead not being.
I am hoping it is related to our spring?
Further to this, these varieties have been deemed "resistant" any opinions or comments on their viability? I continue to monitor, but as we continue to see White elms succumbing to Dutch Elm disease I hesitate to increase percentages.
Any comments or similar experiences are appreciated.
