When to prune raspberries

In Pennsylvania, March is the best time to prune raspberries because any cane dieback from cold will be apparent, and they can be dormant pruned any time the canes are fully dormant.

The window: March in Pennsylvania, or any time the canes are fully dormant; summer red raspberries are pruned in spring and again immediately after harvest.

Any cane dieback from cold will be apparent in March.
The canes are fully dormant.
The canes that produced fruits are ready to be removed right after harvest.
Tall canes over 5 feet are cut back to 4.5 to 5 feet.

The mistake to avoid: Do not leave the canes that produced fruits standing; they should be removed immediately after fruiting.

Timing varies by region and year; your local extension office is the closest authority.
