The best time to prune arborvitae is November through March. (there is also a window in June and July).
Be careful not to cut into old wood that has no needles/green, (like all the way back to the trunk as they can not produce new green growth from this area.
Here is our pruning publication: http://extension.umd.edu/sites/default/files/_images/programs/hgic/Publications/HG84_Pruning%20ornam...
