pruning thornless blackberries

Question

The bushes are about 6-9 feet. it does look like they are starting to bud. We did get them pruned earlier, what should we do now?

Answer 1

The answer really depends upon when you had the plants pruned before. Blackberries should be pruned twice per year – once in the summer after fruiting to remove all the old canes, and once in the spring to trim the tips and encourage branching growth. If you’ve already trimmed the tips this spring, then there’s nothing else you need to do. (Although you could cut them down to a more manageable 6 feet or so. You’ll miss out on the fruit from the tops of the canes, but they’ll be a whole lot easier to harvest).
