A number of my summer raspberries are trying to turn into autumn
fruiting ones, by fruiting now on the new canes that would normally
fruit next summer.

What should I do with these canes?

a) Just leave them alone
b) Cut them out to ground level as I cut back the other summer fruited canes
c) Cut them down to about 9" as you do newly planted canes to encourage
new canes next year
d) Something else (other than eat thre raspberries, which of course I am
doing!)
