All the wild blackberries, at least in the broad area of Ga. where I live, have been ruined by blight for last 10 yrs. or so. Plants grow rampantly, but when berries should ripen, they turn to hard seedy knots. Don't know anyone who has any that aren't affected. If I were to buy some non-indigenous ones, would it be inevitable that they'd get it, too. Rather not grow them than to have to spray chemicals. Would loganberries, boysenberries, raspberries, etc. also be prone to get the same disease?
