Winter damage on conifer shrub
Hi everyone, we recently moved into a new house with nice landscaping, but after brutal winter here in Toronto (I believe this is zone 6 Canadian, or zone 5 US). it clearly needs some love. There are a few conifer shrubs that exhibit (winter?) damage. Can you tell me what this shrub is? Foliage looks like arborvitae, but we're new to this.
One of the shrubs is completely yellow/white after winter, while for others damage is partial. What can be done?
Will it come back, do I need to prune out all the damaged parts? What to do with the one that is completely yellow?
Thanks a lot!
