I planted my first 4 blueberry bushes 5 years ago (3-year-old plants Bluecrop, Elizabeth, Duke & Bluejay). My question is: Is it normal for a Duke to be tree-like? It only has 1 stem coming out of the ground which is getting to be close to 2.5 inches in diameter. It produced gangbusters of fruit the last 2 years. I've read you should prune canes older than 8 years, but that would mean cutting off the entire plant!
