Everbearers can set fruit on the very ends of each primocane in late summer season or early fall. Then, all through the subsequent summer season, they’ll set fruit on what lastly turns into their floricanes.
The right time of 12 months for pruning raspberries
Most raspberry growers reduce spent canes all the best way all the way down to ground stage as quickly because the harvest has ended and vegetation are dormant. Alternatively, you can wait until very late winter or early spring to prune.
