Despite the name, climbing roses won't really climb without the aid of support ties and some training. However, the hybrid multiflora will grow along structures, from curved arches to simple posts. Multiflora roses are a hardy variety and will tolerate heavy pruning and training. Avoid pruning plants for the first year of growth. Prune older plants in April or May just as buds develop new green shoots. The hybrid multiflora rose blooms in pale pink and white petals.
Plant hybrid multiflora roses close to supports such as a trellis, an arbor, a post or an archway. Make sure that wall-mounted trellis supports are set at least 3 inches from the wall for good air circulation, according to Washington State University.
Arrange the support so that the first wire or wooden tie point is 18 inches from the ground, with 12-inch gaps between each support from there, according to the Royal Horticultural Society.
Tie canes to the structure when they reach each wire or wood support point. Use loose lengths of string or fabric knotted in a loop around the rose cane.
Thread canes gently through arch or fence supports if training to follow a particular structure. Tie any drooping stems.
Prune back any diseased, withered or weak stems. Train climbing multiflora roses on trellis supports into a fountain shape. Snip off low offshoots to encourage upward growth. Select a few healthy canes and tie one to the left, one straight up, and one to the right. Allow several smaller shoots to fill in between the main growing canes.
Use a saw or loppers to cut off dead and gnarled wood from the base of mature climbing rose plants.
Mulch with 2 inches of aged manure and spread rose fertilizer around the plant after a heavy pruning, according to the Royal Horticultural Society.
