- Raspberries require post and wire support.
- Fruiting crops like lots of fertiliser – use bonemeal in spring.
- Water well in dry spells.
- Harvest June to October.
There are autumn-cropping types – these fruit on this year’s stems. A double fence is best for autumn fruiting raspberries – space two rows of posts 20-24 inches (50-60cm) apart, and stretch wire horizontally across. Use wire as cross ties every 2 feet.
There are also traditional summer cropping raspberries which fruit on last year’s canes. These are best trained with a system of single fence wires and posts (or against fences).
- Summer fruiting raspberries produce flowers and fruit on one year old canes.
- Prune fruited canes of summer cropping raspberries after harvest and keep new growing canes. Cut back all fruited canes at ground level after harvesting. Do not leave stubs which can let in disease.
- As it grows, support strong canes and cut out weaker ones at ground level.
- Through the season loop long canes over the top wire and tie in.
- in February trim these long canes to a bud 4 inches (10cm) above the top wire.
Autumn fruiting Raspberries
- Autumn fruiting raspberries flower and fruit on growth made in the current season.
- Prune all canes to ground level in February.
- Select the strongest canes and only prune off shoot tips that produced fruit last autumn
- Once they have fruited, prune them back to ground level.
