I have a lot of blackberries brushes and was wondering on the canes that are blooming this year do I cut them down at the end of the season? Don't they just bloom one year?
Blackberries have 2 types of canes Primacanes and Floracanes the first year (Primacanes) canes don't do anything but put on leaves. The second year (Floracanes) put on side shoots and flowers that will produce fruit. After the Floracanes are finished they die. Most growers remove the spent Floracanes right after harvest.
