I live in southern Arizona and we have four varieties of Oaks here that lose their leaves in the springtime as opposed to the fall. I know one species is called Emory and another the Arizona White. What the other two are I am not sure.
Are these leaves good for mulch?
My neighbor says they have too much acid. He has a huge pile of them and nothing grows on top of them. The pile is about 20 x 20 feet and 6" deep. It has been there for about 3 years undisturbed and there is very little mulch underneath.
