Hi all, I live in Toronto and I think my Emerald Cedars are dying, or at least something is dreadfully wrong. They were planted in June of 2015 so are 5 years old and have been lovely till this spring. Three of them are going bald at the base to half way up on the interior side which faces the tree beside it. We do not have dogs. I have been told it might be that they need better light. The garden is south facing and they run along the west long side. They don't get a ton of sun till summer I guess. The trees on the east long side (get lots of light) seem to be ok. I will attach some images. Please help!!!
