I moved three arborvitaes (1 five feet and 2 3 feet) from the front of the house to the side, which receives 4-6 hours of sun per day. Before transplanting I cut the dead branches of the small shrubs, which was a substantial amount. The soil on the side is clay and rock, so I amended the soil around the shrub balls with fertilized planting mix and peat moss. The area also slopes down and water is plenty, so I watered only the day I planted and the next day. It's been a week. One of the small shrubs has a whole section light green. Any thoughts why and if I can do anything to save it? Should I cut that part of the shrub to let all nutrients go the healthy-looking (so far) parts?
