Answer: Some arborvitae have upright branches that can, and will, collect snow and sag - or even break off. You can prevent this type of damage by wrapping the plants with soft cotton twine or other pliable string. I'd avoid fishing line as it has a tendency to cut into plant tissue. I loosely wrap my arborvitae by starting at the base of the plant, securing string to the trunk, then wrapping it in a spiral fashion all the way up to the top. The trick is to keep the branches in the same position they were growing before wrapping. If you snug things down too tightly, the plant can be damaged. Be sure to remove the string when threat of snow is over for the season.
