Q.Why Are My Thornless Blackberry Plants Have Only 1-2 Canes?
I had a blackberry plant for a long time. It made new plants and I replanted them. But I never get more than 1-2 canes from each plant. This cane makes usually only 1 or 2 lateral branches. I get blackberries, even quite large but just a few on each plant. All blackberry plants that I see online are very bushy and have many canes, branches and clusters of berries. What am I doing wrong?
