Q Help! Do I cut off ‘Tulameen’ raspberry canes that are outgrowing their fruit cage?

A Growing raspberries in a fruit cage helps stop birds devouring the crop. These tall canes are the result of new plants enjoying the fresh soil that you’ve obviously prepared well. It would be best to trim off the tops of the canes so they fruit lower down, inside the cage. Don’t cut them right down, because they won’t fruit this year and by the end of the summer the new canes will be as tall again. The strain on the plants caused by cropping should reduce the vigour of the new canes and in subsequent years they shouldn’t be as vigorous.
