When I bought my Arborvite it was in a pot and the soil was clay like and dried,, I worked so hard to get
most of the soil off . It was difficult ,, but I did dig a deep hole and planted it with fresh black soil and watered it well.
Now,, as the month rolls the whole arborvite is not green , appears light green and not healthy,, I wonder if it is in shock?
I did apply mulch around it and continue water it when dry.
