Emerald Green Arborvitae Dying?
I planted a few 4ft Emerald Green Arborvitae last fall. I have noticed that they are all brown on the inside, while green on the outside. Is this normal, or are they in distress?

An Arborvitae will typically shed interior needles so interior browning is not uncommon, especially in the fall. These interior needles will eventually drop off. Since these are newly planted, I would monitor them. If you see browning on the outside needles or at the bottom, this may be an indication of other problems. During extended periods with low/no rain, you may want to lay a hose at the base and run it slowly for good absorption to the root ball. Move the hose periodically around the base.
