What's the earliest I can winter prune my roses?
I usually winter prune my roses around New Year. However, my roses never fully recovered from a sprinkler disaster this summer, and although they've just finished a bloom cycle, they're looking very leggy. I read on the Huntington website that they start pruning their (climbing) roses in December, but I wonder if now is too soon, and I'd be leaving any early new growth vulnerable to frost?
Thanks for your advice.
