emerald green arborvitae Smaragd

Question

Can these evergreens be trimmed to maintain an 8 foot height?

Answer 1

I don't usually recommend this. The trees are best left to their natural shape. There are some that grow into hedges, and some that can handle pruning more than others, but should you decide to prune it, you may not get very desirable effects. An alternative, if possible would be to replace them with a more suitable variety for the area.
