Two white firs have bit the dust :-(

Asked May 9, 2018, 6:57 AM EDT

Good day! Over the last two summers we’ve lost two white firs that were part of a recent landscaping project. We believe we’ve provided ample watering (perhaps too much?) and care. However, we noticed a steady decline of the fir’s new growth and then the subsequent brown branches begin to appear as the summer goes by. We previously had a very large white pine near this location. Any thoughts?? Many thanks!!!

The following sites will help you diagnose why the older, inner needles are turning brown and dropping on your fir and spruce trees. A hand lens will help you find the tiny fungal signs on the needles.

Common diseases are Cytospora canker and Rhizosphera needlecast.

Thanks sir! I thought it may be the same things as mentioned in these sites, but entire branches turn brown. No new growth appears and now I think she's already dead.

Cheers
