Why Are My Arborvitae Turning Orange

Answer: The browning of the inner foliage is probably due to seasonal needle drop. It’s normal for evergreens (pine, spruce, fir, juniper, arborvitae, etc.) to shed their oldest (innermost) needles in fall. The innermost needles gradually turn yellow or brown and drop to the ground.

Can a Browning arborvitae be saved?

Brown arborvitae can be saved from conditions that cause it to brown, but it may not be as healthy as it was. But that does not mean it cannot be saved. A branch that has turned brown can grow out and parts of the branch closest to the trunk will grow to their natural green.

What causes an arborvitae to turn yellow?

The arborvitae plants often need a lot of water and can turn yellow if too little or too much water is given to them. If they are watered too frequently, and the soil is saturated, then that can cause waterlogging. Waterlogging can then lead to loss of roots as well.
