Thanks for the replies, they are summer fruiting,I cut the canes that had fruited last year.
We've had a very dry 5 weeks here in Dublin but I'd gave them a good drink once or twice..
Theres loads of new growth that still looks healthy but all the tall canes wre lush and full of flowers until now too.
2 plots uphill from me had sprayed a few weeks ago,not sure how still it was when he sprayed but the plot inbetween us doesn't seem to have suffered....
I'm at the bottom of the hill and get great flow of ground water,even in the driest times the soil is moist 6inches down
Ta loads
