Hybrid multiflora climbing roses are a hardy perennial with strong pliable canes. This variety of rose boosts fragrant double blooms in multicolors of red. The multiflora climbing rose grows best in USDA zones 3 to 9 and grows about 8 feet tall with some varieties getting up to 15 feet tall. These vigorous climbers are pest-resistant and with a little patience and care, can be trained up a trellis to provide a wall of color to the home garden.
Plant the hybrid multiflora climbing rose in a sunny location near a wall or fence. Be sure the soil is well-draining so the roots do not get soggy, which can cause root rot. Mix compost into the soil and throw a handful of bone meal into the hole before planting. This adds the necessary nutrients to the soil, including calcium, which makes for a healthy, strong rose plant.
Place a trellis or wooden lattice in front of the wall or fence about 4 inches out. Plant it deeply into the ground, at least 8 inches down, so it is well-secured and will not fall over.
Allow the climbing rose to grow without pruning for at least one year, preferably two, to allow enough growth to be able to train it onto the trellis. As it is growing, train the canes of the rose to grow up over the trellis, by weaving them in and out of the open spaces. If necessary, use pieces of nylon to tie the canes to the trellis to hold them. As the plant grows, retie and continue weaving the canes up and through the trellis.
Spread the canes of the hybrid multiflora climbing rose over the trellis into a fanlike shape. Train the middle canes straight out and the outer canes spread out to the sides. Weave through the trellis and tie as necessary to hold.
Prune the climbing rose after one to two years, when there is sufficient growth allowing it to grow well over the trellis. Cut out any dead, weak or cracked canes clear back to the ground. Cut off any spent flowers and suckers that are growing up from the base of the plant. Cut off faded flowers during the growing season to increase the number of blooms.
