I’m not sure if what I’m attempting with my PAF blackberries is different from you are doing. The early ripening floricanes was mainly what I was after. This happens ahead of the arrival of the swd. I didn’t know what to expect from the timing of ripening fruit on the primacanes but I was hoping they would ripen after the swd was gone for the season. I was wrong as the primacanes started ripening way too early and in the middle of the swd peak. I started slipping on my bags over the stalks of primacane fruit and they have worked well. Obviously it is not practical to bag a whole crop of these but it does give you a few to snack on.
