It's Mid-September/October
Why are my evergreens turning yellow/brown on the inside?
SEE PICTURES BELOW
Don't worry, this is mother nature doing her job. It's 100% natural and happens in the fall.
Trees lose their leaves in the fall; evergreens shed their inner growth in fall. It happens every year.
Evergreens such as Arborvitae (Thjua), Pines, Spruces, Hemlocks, Cedars, etc. ... shed their old growth from the inside to make room for fresh, health new growth in the spring.
You will notice yellowing/brown needles or foliage on the inside of the plant.
DON'T PANIC
While it can be unsightly it's nothing more than a natural process that occurs every fall.
