Greetings!
I have two clusters of filbert trees in my yard and both clusters have done very well in the past. This year, the one cluster of trees doesn't have any foliage or blooms on it and is completely bare. The bark around the base of this tree is peeling off in layers and has white spots under the peeling bark.
Any suggestions on what this might be? Can I save this tree or should I cut it down before it infects the remaining trees? I live in central Ontario. Thanks in advance for any help.
