Also, prune cane berries when all their leaves have fallen. The easiest way is to clean out half the berry vines every two years. Then you will always have a year-old patch to bear fruit the following summer, while you clear the other patch by clean cutting. Prune grapevines after all the leaves have dropped. Grapes bear on second-year growth, so prune to encourage this fruiting wood.
Roses are fully dormant, so prune any time.
