Hi! It's been a reasonably cold Atlantic Canada winter. But we had a very warm period a couple weeks back (several days getting up to the plus 20's) and then shortly afterwards another cold spell back below freezing, lots of snow. And now I notice that some of our many Balsam firs are looking quite "rusty" in places. View attachment 233625 View attachment 233626 View attachment 233627 I'm totally new to forest living, so really don't have a clue as to what the cause is. The tree pictured is kind of on its own in a bit of a clearing, and I could imagine that the ground under it might have gotten quite warm during our 'hot spell' and pulled it out of dormancy (and new growth could have been 'frost bit' shortly afterwards). Or is there a well-known 'red blight' that attacks Balsam Firs?
