How to prune raspberry 'heritage'

Late winter (February in the Northern Hemisphere), after the last fruit and before new growth starts. Cut all canes flush with the ground using loppers or secateurs. Clear away and dispose of old canes (do not compost if disease is present). Thin emerging new canes in spring to 10–15 cm (4–6 in) apart, keeping the strongest upright canes and removing weaklings.

Annually — full cutdown every late winter. Heritage is an autumn-fruiting (primocane) raspberry — it fruits on the current season's canes. After harvest, cut ALL canes down to ground level in late winter. This is the simplest pruning regime of any fruiting cane: no need to identify old versus new canes. New canes will grow in spring and fruit from late summer into autumn.
