A light shearing may be needed to maintain size. Heavy snow can cause the plants to split and open up. I have tied them together to bring them back into shape. Like most Arborvitae it will accumulate a good amount of dead foliage in the center. I like to tap the plant with the flat side of a leaf rake to knock lose the brown foliage. All Arborvitae are among the easiest of the evergreen shrubs to transplant.

Author's Notes
This has been a very hardy Arborvitae for me over the years. Some of the first plants I installed over 17 (2012) years ago are around 8-9 feet in height.
