Prune out all weak, diseased or damaged canes in March or early April. Leave only the vigorous canes.
Prune off the dead tips of last year's fruited canes, leaving the bottom portion for this summer's crop. Prune down to living tissue. This should also be done in March or early April.
Thin out raspberries to three to four healthy canes per foot of row in March or early April.
Locate the fruited canes after the summer crop has been harvested. Prune out these canes 1 to 2 inches above ground level. Leave the newest canes for fall harvest.
Prune all canes 2 to 4 inches above ground level in March or early April.
Allow new canes, called primocanes, to grow throughout the summer.
Harvest raspberries in late summer or early fall. No summer pruning is required after harvest.
