Are you pruning them correctly? They need pruning in late winter as shown here
and then in June you need to cut the side shoots back to five leaves.
Thin out the fruits in June, removing half and use these for cooking and leaving the rest to ripen (watch out for marauding birds - you may need to net the bushes, the old gardeners would drape them with old net curtains).
Keep the area around the bush free from grass and weeds and feed in late winter/early spring with Fish, Blood and Bone and a bit of extra potash if possible.
In the autumn I clear any fallen leaves and mulch with well rotted garden compost or manure.
