Raspberry Leaf damage

[VegBoy]

Hi,

Can someone please advise what is wrong with my raspberries? I’ve had a lot of intense sun but also some heavy rain. Until the last week or so they did fine and we’re all green.

Thanks

How long have they been in the pots, have they had any feed? Rasps like a high potash feed, in liquid form either a tomato feed or a seaweed based one, make sure the pots can drain away any excess water too.

Got dried out and scorched in the hot weather. I'd never recommend growing raspberries in pots but if you have no option, get some large deep trays, half fill them with gravel or sand, put the raspberry pots on those and make sure they are kept full of water at this time of year. Your rasps are trying to grow fruit and new canes, so its thirsty work for them.
