Rose pruning advice
I am a very amateur gardener and believe that I may have left it too late to prune my Mortimer Sackler rose which I am encouraging to grow up and onto a fence. I understand that it is a 'tall shrub rose or short climber' and so have I missed the opportunity to prune it already this year? If I prune it now will I prevent it flowering or encourage longer flowering for the forthcoming summer (considering that I think we may be a month behind in the calendar due to the awful weather). I live in the south of England. Thanks in advance for any advice.
