Planting Emerald Green Arborvitae On A Rock Wall

Question

Can I plant emerald green arborvitae on top of a rock wall near a fence?

Answer 1

As long as there is enough soil to sustain the tree, it would tolerate the planting. If there is no soil, I would not recommend it. They will not grow, happily, on rocks.
