Keep watering raspberries until the ground is frozen. Plants usually go dormant sometime in November and most of the leaves drop off. At this time give them a deep watering, down to the root zone, to prevent winter root and crown damage from desiccation.
Mulch with dry leaves to help maintain adequate soil moisture.
Prune only the canes that might get broken by a strong wind or tie them together for extra strength. Prune in late March.
