First Year Blackberry Canes
Certified GKH Gardening Expert
First-year canes, also known as primocanes, appear as stems that arch or trail along the ground. They usually bear large compound leaves with five or seven leaflets; they do not produce any flowers or fruit. Second-year canes grow to become what is known as a floricane. The stem will no longer grow taller, but will begin to produce lateral buds and flowers. Also, these normally have smaller leaves with only three or five leaflets.
