I noticed the same thing this year. The wild highbush blueberries didn't seem to produce this year at all. I too have a couple of good spots around Parkdale and they are sparse. Maybe it was the wet spring and summer?
I did find a small area near my house where the lowbush are doing okay and I am going to grab some of them Saturday.
The cultivated blueberries seem to be doing fine. I haven't heard any farmers complain and the farmstands are selling them cheap.
The wild cherries seem like they are having a heavy year. This is one of the best I can remember.
