Hi,
You will find a picture of my climbing rose 'Autumn Sunset' that was planted in 2015. It was about 6-7ft tall and I trained it on an arbor (pic attached) and it probably had about 15-20 flowers through out the whole season. I was researching about climbing roses and read that they should not be pruned for the first 3yrs except for the dead canes. So I waited until mid may to see if the canes would start sending out new growth but they did not and instead the growth came only from the base. I had to cut all of the previous years growth since it looked dead and ugly on the arbor. Not sure if I made a mistake. This year's growth is about a foot with a few buds forming already. Let me know your thoughts.
