Problems with raspberries

Had a few canes that set fruit then leaves turned brown this week and died, any ideas??

Yep plenty

There was an earlier post on this one, and I have also had leaves going brown, but the fruits are still growing and ripening - there must be an explanation for it, but because of the heat we had, I sought of wondered if the leaves were shutting down above the fruit so the plant could put all its engergy into the ripening  / reproductive process, as its only happening above or around the upperfruit bearing stems.

Someone will probably give a more scientific reply - I'm not a scientist

I have had the same thing happen - the first time it's occurred. It's not all of the canes either. I put it down to some sort of stress, perhaps the warm spell earlier made the leaves more susceptible?? I replanted my raised bed with the same canes so I was worried that I had inadvertantly done something to them. I't bleating down now so will see if it continues but I have been watering well. 

Hey Gillie, do you want some of mine?  The blooming things are popping up all over the place - mainly where I don't want them lol... very blooming resiliant they are

Thanks Casey, I would love a trip to Alsace but it is a bit far.

Actually I seem to have problems with certain varieties.

I have a great hedge of Autumn Bliss, but the better flavoured Joan J disappeared.
The recently revived ones are Malling (I think) Promise, but the later, better flavoured Mallings have all upped and died as did various attempts at 'Glens'. 

There are a few raspberries in the middle of the currant bushes too, but who knows what variety they are!

Allotment Jon - I don't think that raspberries will do well with weed suppressant fabric,  the new canes need to be able to grow up around the old ones.

Cheers,
