Emerald green arborvitae turning yellow
We moved into a new house last December and had about 40 emerald green arborvitaes planted in our backyard for privacy in the spring. They are mostly 3-4 ft tall and many of them are continually turning yellow. I've been watering them daily first two months and about twice a week now. At first I thought they were turning yellow from the move and would eventually recover but it's been at least 3 months now and I am still seeing new yellow spots on many of them. My lawn care guy said it's due to broken foliage but they've been in place for several months and I am still seeing new yellow spots here and there. One thing I noticed is cobwebs on many of them, not sure if this is related. Appreciate any suggestions you may have.
