Tieing down & training climbing roses

[new gardener 1052]

Evening all
When should the tieing and training of climbing roses be done? How long should the stems be left before training?

Mine had a stem about 12 inches long I tried to tie it and it broke I'm gutted now

You usually do it in early winter, doing the pruning at the same time.

I only tie branches up during the year if they are blowing about and look as if they will break.
At this time of year they are full of sap and likely to snap if you try to bend them.
