Pruning roses and clematis with new growth
due to various building works I have not been able to do much in the garden, now it's clear and I was going out to start pruning Group 3 Clematis and some Roses, but I see that all of them have new growth! I'm based in London.
Is it too late to prune? Should I be cold-hearted and just do it? I am afraid of losing some of the growth for the year.
