Q.How to train climbing roses
Hi! I am trying to grow roses for the first time, and bought two, bare-root, from David Austin USA. One is a Claire Austin climbing rose, and when it arrived, it was smaller than any of the pictures I have seen of climbing roses.
How should I approach training it? It has some new growth: should I start tying longer pieces to the trellis, or should I let it get larger first? If so, how large? And should I eliminate the smaller of the new shoots?
I’ve been having trouble finding information about very young roses online, and would greatly appreciate your advice.
Sincerely,
Lorin Kleinman

I believe in training climbing roses as soon as possible. Tie the canes off to your desired support structure early on as the canes become large enough to tie off well.
