Answer: The answer depends upon the design of your trellis. Climbing roses won't twine like some vines and so will need to be tied onto a support. If your trellis has openings you can guide the canes through one opening and out another; if the trellis is a fan-shape, you'll need to tie the canes at intervals to hold them in place. Use the stretchy green plastic tape found in the garden section and tie the canes loosely. Or, try the new velcro ties. You can move these or readjust them as your climber grows. Whatever material you use (old nylons cut into strips, soft twine, plastic tape or plasticized wire), be sure to check periodically that it isn't so tight that it's binding the stems and canes. You want to support the canes, not cut off the circulation!
Best wishes with your climber!
