Do you tip prune laterals on blackberries too?
I know about tip pruning your primo canes and it has worked well but I have some laterals that are getting mighty long too. Do you tip prune these as well since some of them are getting as long as the primo canes did - like 10-20 feet?

It is recommended that you prune lateral tips back in the spring. How much is a point of discussion, with some sources recommending to tip to 18 inches and others suggest cutting them back by 1/3 to 1/2.
