In early spring a tree professional cut back our arborvitae hedge to encourage growth inside the hedge. We have not seen any new growth. There are large gaping holes in the hedge. Is there anything we can do to get new growth?

They don't take well to pruning, so it's pretty much a wait and see sort of thing. You could try giving them a little dose of fertilizer and make sure they're watered well to see if this helps at all.
