The Q&A Archives: arbor vitae shrub starting to turn yellow

Question: On aug.1 I planted 18 shrubs 4-5 ft.tall. I notice 1 shrub is turning yellow. I water every 4-5 days and used miracle-gro with hose application. What is wrong with this shrub?

Answer: Unfortunately, based on your description I am not certain what is wrong with your shrub. It is possible you may be over or under watering, or you may have overfertilized, or it may have suffered some physical damage or be planted too deeply or there may be some other problem such as a pest or disease at work. Too, arborvitaes tend to naturally shed some of the lower and interior foliage each fall, so it might be normal depending on the pattern of the discoloration. This type of symptom is very difficult to daignose long distance so I would strongly suggest you check back with your retailer and possibly also with your local county extension for help troubleshooting the problem. Also, I should mention that it is late enough in the season that you should no longer be fertilizing, this can encourage late growth that will not have time to harden off before winter cold sets in. Good luck with your arborvitaes!
