Last fall, we had 20 or so 5' arborvitae planted by our gardening guy. They browned up some during the winter, but pretty much came back over the summer. Now they are all browning out from the center. It looks pretty widespread and there is a lot of browning going on. Are we going to lose them? I hope not - it was a lot of $$$ to plant them in the first place. The gardening guy says we need to water them - which we are doing, but it looks pretty bad. Any advice or anything? We live on Long Island, NY.
We planted arborvitaes because we thought they were fairly hardy and easy to care for. It seems to me they are awfully finicky. We should have gone with hemlocks.
