Recommendations were to pick several of the most desirable fir trees to keep, then make multiple drip/ soaker hose rings out to the branch drip radius, heavily mulch the same and then periodic deep soaking. The additional water will encourage much more sap production which repels the beetles. They will hopefully then go for weaker trees.
We had a consultation last Spring with Nate Berner a certified arborist. We have firs dying, as we learned due to the fir engraver beetle. He gave us a strategy to hopefully reduce further infestation especially of trees near the cabin. We really were impressed and it has been worth the reasonable consultation fee to save some trees. Also very nice guy. Check out his website.

I have a large cedar tree that looks to be dying. It has very few limbs at the top, but they’re still green. Does anyone have a recommendation for an arborist who can evaluate the tree?
Thanks in advance,
Scott
