FAQ

Our 6-8 foot Emerald Green Arborvitae, planted 10 years ago, now have significant brown foliage in the center despite using a drip line with fertilizer last summer. What could be causing this, and what do you recommend?

It is tough to give accurate diagnosis without inspecting. But given my experience with Emerald Green Arborvitae, it is common for the interior to brown up due to lack of light, especially if they have shade on one side. Also, they are very susceptible to spider mites and excess watering will cause root disease to develop. After establishment the watering should be one or two times per week.
