With the introduction of 'Trier,' in 1904, a new type of rose was born: the hybrid musk. Bred by a gentleman who held the scent of roses in high regard, the hybrid musk rose release freely into the air. The hybrid musk rose is a shrub rose with some varieties that can be trained to climb and others that can be grown as hedges. They bloom in shades of pink, yellow, peach and red. The hybrid musk rose is hardy in USDA zones 6 to 10.
Grow the hybrid musk rose in partial shade. This can mean either morning sun and afternoon shade or dappled sunlight.
Apply a 2- to 3-inch layer of mulch around the base of the hybrid musk. Spread the mulch out to the drip line, keeping it 2 inches from the trunk of the shrub. Rake back the mulch in spring, dispose of it and apply a fresh layer.
Water the hybrid musk rose deeply once a week, more often during particularly dry periods. It's best to water deeply and slowly, and a soaker hose works well for this.
Fertilize the hybrid musk rose when you notice the first leaves in the spring. Use a rose food at the rate indicated on the package. Apply the fertilizer monthly, but reduce the strength to half during June, July and August. Withold fertilizer six weeks prior to the first frost date, and resume again in the spring.
Inspect the hybrid musk rose frequently for signs of insect infestation. Hybrid musks are prone to powdery mildew, especially if planted in cramped quarters. Remove any infested leaves and destroy them. Prune any surrounding trees or other foliage that may be crowding the rose bush. Fungicide is not recommended for the hybrid musk rose (per antiqueroses.com).
Control insect infestation on the hybrid musk rose with insecticidal soap, used according to package directions.
Prune the hybrid musk rose lightly. While dormant, remove any dead branches and those that cross over others.
