Answer: I think only time will tell. Wrapping them can help protect against icy winter winds but wrapping can also hold in too much moisture, which can lead to other problems. At this point, just water your arborviataes as usual and wait for new growth. Just as new growth is beginning, prune your arborviates back by a few inches to encourage overall growth. This will remove some of the browning foliage and with any luck the new growth will hide the rest of the brown foliage. Hope your arborvitaes recover!
