Mushy Caneberries

Asked July 13, 2020, 2:21 PM EDT

We have been growing boysen and loganberries for years. This year the we have lost around half of the crop due to "mushy when picked" berries. First thought of worms, did not find any. We only have a couple plants of each, but were curious what might be the cause for this. Thanks for any help you can give us. Sue Mills
