Last year and especailly this year I got almost no saskatoons on my 8 saskatoon bushes. Setting aside the three young bushes which look healthy, the other five bushes started off the year well but then the leaves started to turn yellow and the berries which had looked so promising stopped growing and were approximately half size. Some online research suggests the culprit might be Entomosporium leaf and berry spot disease. What do you think? If it is, what do I do about it? (Picture attached)
