Once your summer-fruiting raspberries have finished cropping, it’s time to cut out the stems that bore fruit this year.
This encourages new stems to grow from the base, which will carry fruit next summer. The suckering nature of raspberry plants means that if left unpruned they become very congested, produce small fruits, and outgrow their allocated space. Also, the fruited stems will gradually become weaker each year and eventually die.

What about autumn-fruiting raspberries?
Autumn-fruiting raspberries produce canes that flower and fruit in the same year. Simply cut all their canes to the ground in winter, to allow new canes to grow come spring.
