Hello! I have a Weeping False Nootka that was transplanted seven years ago and has been thriving until this spring. It was a particularly cold, long winter in the Niagara region and I have noticed some other nootkas nearby that show similar stress. The sheltered side of the tree (away from open field) seems all right but the other half has many brown branches as do parts of in the centre of the tree. Is the damage likely caused by the combination of cold and wind? (In other years, the tree showed no response to the same windy conditions.) Should I fertilize? Should I prune the brown branches? It is a particularly beautiful, well shaped tree and I would hate to lose it and so would appreciate any advice you could offer. I hope I have hit the correct forum.
