Roses are a versatile group of flowers, adaptable to growing in containers, as a shrub and, when trained, along climbing structures. You must train roses because, unlike vines, they do not have tendrils that can secure to vertical surfaces. As roses climb fences, arbors or trellises, they give an outdoor space color, texture and vertical interest. When training roses, it's equally important to get the timing right as much as the technique. Young canes rapidly grow after a pruning---in the early spring or late winter---so you should not train roses at this time.
Select the right type of rose for the climbing structure. Climbers and ramblers are suitable for most climbing structures as their canes may grow up to 20 feet in length. Hybrid Teas and Pemberton's Roses are good choices for pillars.
Put on gardening gloves for protection from thorns on the rose canes.
Arch the canes of the rose over the climbing structure. Bring the cane's ends lower than the middle, bending them horizontally, which ultimately will produce lateral shoots and develop new blooms.
Use plant tape to secure the cane's center and ends onto the vertical structure. If training to climb on a trellis, thread the rose canes through the interstices of the structure and omit using plant tape.
Repeat the arching and securing steps with the remaining canes along the support. Wait 1 to 2 weeks, and add additional ties to the canes to reinforce the support. Prune the rose in early spring to avoid unsightly overgrowth or deterioration.
