In my area of SE PA. we have a bunch of acorns, mostly Red Oak. Some White Oaks are dropping but not like the Red. White Oaksdo not drop everyyear either. I have two BIG White Oaks in my area and they have'nt dropped acorns in the last two years. This year I've seen some. Acorn drop is tree specific at times,you can have an area of Oaks but not all of the trees in that area are dropping!
