Raspberry heat stress question
I've got a row of Heritage and a row of Caroline both of which I treat as fall bearing only (cutting all canes down at winter time)
When I prepared the beds I made sure they were in full sun. I kind of thought that was a mistake even before this blistering summer, as my Caroline showed evidence of White drupelet disorder on some berries the last couple of years.
I sort of wish I'd have made my bed in a partial shade location, it doesn't seem to affect the wild raspberries to be in partial shade.
Anyway, to my question: The Caroline's are burning up and it doesn't seem to matter how much water I give them. The Heritage seem unaffected given the same amount of water and also in full sun.
I've alread written off this years crop for the Caroline, bur I'm worried that this heat stress is killing them. They are mostly dried brown at this point with some green on the canes and a few leaves.
If I prune them down to the ground do they have a chance of surviving to grow again next year?
Had I know how they'd react to this heat/sun I'd have maybe built some kind of shade thing for them....
