My prized, formerly gigantic, fir is withering. We had drainage trenches dug and it's my opinion that this is the cause of the tree's distress. Three years has passed, continuing to worsen. How can I save and improve the health of this magnificent tree?

Expert Response
Trenching and other major disturbance damaging roots or compacting soil can certainly cause trees to decline or die. To focus on what can be done, I have questions for you. Is the photo a current view? It does not look particularly "withered". Both the new growth and last couple years of foliage appear to be OK.
How much of the rooting zone of this tree was disturbed? Were any large roots severed? Is it a yard tree or in the forest?
Also, I would like to confirm the species of this tree. Could you send a close-up photo of the cones, the foliage, and the bark? From your photo, it looks like a Douglas-fir or a spruce, but not a true fir (genus Abies).
Providing an occasional deep irrigation during summer drought could be helpful, depending on the species of tree and the existing moisture supply from your soil.But it is also important not to over-water native conifers.
If possible, please respond by emailing me directly rather than ask-an-expert.
