sago trees have green on the bark

Question

Sago trees have green on the bark. Is that normal? I am taking care of 2 sago trees in my yard. They look good but for the light green on the bark.

Answer 1

It is very difficult to determine what may be on your Sago Palms from this description.
I have listed links for you that will help you determine if this is a fungus and what coarse you will need to take.
