Separate thread as I didn't want to divert the other one about the rose in the pot but it's another one about roses and winter
First frost has been - and normally I'd want to winterise roses before that. I'm in London, and our frosts are not severe (though it did make it to -3) and the garden is not large, well fenced so does not get much wind chill
With the warm autumn, the roses were putting forth buds until about a week ago, and are still flowering plus there are a couple of unopened buds.
I was waiting for them to finish (hoping that would happen before it got properly cold) before final deadheading and I also want to shorten a few of the very long stems.
Is it still a good idea to do this (between waves of frosts - looks like the next week isn't going to be that cold here) ?
What's the latest I could leave it - wondering if I should wait until flowers are over, or sacrifice them?
