Gardening

All the canes with no flowers/berries this year will fruit next year. Don't cut those ones back. You will know which ones to cut out, after the second year when they fruit, those canes will be dead so they can be cut out. I don't have a trellis but grow mine along a wire fence and I do fasten some of the longer fruiting canes onto the fence to keep berries from being too close to the ground. I have noticed that canes that are on the ground will root at that point, and so I let the first year canes hang down to the ground if they chose.
