Summer raspberry plants - leaves yellowing... browning... dying... Any ideas?

January Man

Hi all

Some of my summer raspberry plants are looking quite sorry for themselves   I wondered if anyone with experience and/or knowledge might know what is causing it.  Below are some photos...

Could it be as simple as lack of water?  Obviously it has been very hot, and I go for the heavy water once a week approach.  Maybe I've not done enough, although in all honesty it's usually the case that I overdo watering!  

Many thanks

Is it sunny there? They look a little scorched. As scroggin says, they will die back anyway, maybe just doing it a little earlier than normal because of the weather. Cut down any that are thoroughly brown and any stems that have borne fruit this year and now stopped producing. You could give them a good drink, but they'll probably not fruit much more now anyway. The autumn fruiting ones take over around now.

Hi

Thanks for the responses.

@scroggin - I'm pretty confident that all we have there is this year's canes and the new growth which will fruit next year.

@raisingirl - yes, it has been hot and sunny here and that could well be the trouble I guess.  I didn't realise that it is around now that the autumns take over from the summers, so that's good to know.  We do have some autumn raspberries and they are looking quite healthy; although there's nothing near ripe on them yet.  

The only thing of slight concern is that some of the summer's next year canes have brown dying leaves on.  Is that anything to worry about?  

Thanks again

I have the same problem. Interesting about the pruning, but mine are new canes this year from cuttings at our last house, should I prune these? _they had miserable fruit this year. I think leaves are scorched. Normally I put wood ash around roots and then lawn mowings to keep in moisture after watering. First time I have come across this yellowing. Autumn Bliss seem Ok though at end of row. Plus strawberries in pots further along thriving.

It may well be lack of water if this year's canes are dying. They have shallow roots, they also fruit well in partial shade and cool summers, so this weather is probably not a raspberry's idea of a good year.

Hello scroggin where have you been, some of my autumn fruit raspberries look like they have died as well, I have been watering them, dont usually have to do it very often, but it has been extreme, 7 weeks without rain.
