First Year Blackberry Bushes

Question

Just planted blackberry bushes earlier this summer. When is the first time I need to prune them? They bore only minimal berries this year but are looking very healthy and have grown an enormous amount. What is my next recommended process, please?

Answer 2

If you have a lot of new growth, prune out the weak canes. You will also want to prune out last years growth. In the spring, use a balanced organic fertilizer.
