Topping an immature arborvitae

Emerald Cedar - Thuja 'Smaragd'

I planted Emerald Green arborvitae 2 years ago and this year they were about 6' high. The landscaper topped them back maybe 1', and that meant cutting into the wood. These plants should get to 10' to 12'. Aren't they permanently stunted now that they've been topped like this?

I live in the Detroit, Michigan area.

Fortunately, Thuja just like putting out more growth from the top - even after a drastic haircut.

They will make many new leaders from below the cut, which will continue to grow.

Eventually, the full height hedge will just need a light trim, to keep it in line.

Sometimes one or more of them in the row grow a little more and need a harder pruning, but in time they seem to all toe the line and stay the same height.

They also make new growth out of the sides, not just the top.

Don't worry, it will all work out fine!
