With this year’s mild winter I’ve started pruning the climbing roses New Dawn and Blairii no 2 early, but not to drastically. Because my garden is facing North I never prune my roses very hard, in order to make life not too difficult for them. Thus they can profit the most (I think) from the sun, since most of the sun only reaches the top branches.
The other Old shrub roses in my home garden require for know only the removing of dead wood, with the exception of the English rose Gertrud Jekyll. I find that the English roses need harsh pruning in order to maintain their shape.
I can’t wait to see the roses bloom and smell the heavenly fragrances.
