We had planted 6 Emerald Arborvitae in large cedar containers. We have these three containers sitting on our deck for privacy. We had them done professionally to make sure they took. They were planted in May. They did well until we took the plastic wrapping off this March. The south exposure is brown on all 6 of them and seems to be getting more pronounced. The north exposure is not as bad. I'm desperate as this was a $2,000 investment. Home Depot will replace them, our warranty is up in May. The company that planted them wants another $500.00!! Help!
