WaterHybrid Tea Roses, like the Royal William, should be watered deeply and infrequently to encourage root growth. During the growing season, water approximately once every week with about 1 to 1.5 gallons per bush, ensuring the soil is moist but not waterlogged. If the weather is particularly hot or dry, increase watering frequency to twice a week. During the winter months, reduce watering but do not allow the soil to completely dry out. Always water at the base of the plant to avoid wetting the foliage, which can lead to diseases.
LightHybrid Tea Roses, including the Royal William, thrive in full sunlight. They require at least six hours of direct sunlight daily to bloom optimally. The best spot for these roses would be an open garden area or a bed that receives unfiltered sunlight for the majority of the day. Avoid planting them where they might be shaded by trees or buildings, especially during the morning hours when the sun helps dry dew from the leaves.
TemperatureHybrid Tea Roses like the Royal William perform best in moderate temperatures and can survive in USDA zones 5 through 9. They can endure winter lows down to about -20°F. During the growing season, an ideal temperature range is 65°F to 75°F. Extreme heat can be stressful for roses, so some shade during the hottest part of the day can be beneficial to prevent overheating.
PruningPruning Hybrid Tea Roses like the Royal William is essential for maintaining plant health, encouraging blooms, and shaping the bush. It's best to prune early in the spring, after the last frost but before new growth appears. Remove dead or damaged canes and thin out the center of the plant to improve air circulation. Cut back remaining canes by about one-third to one-half, making cuts at a 45-degree angle above outward-facing buds. Prune again lightly after each bloom cycle to remove spent flowers and encourage new ones.
CleaningAs needed
SoilThe best soil mix for Hybrid Tea Roses like the Royal William rose should be rich, well-drained, and loamy with a pH of 6.0 to 6.5. Amendments like compost and aged manure will improve soil fertility and structure.

Life cycleThe life of the plant commonly known as Hybrid Tea Rose 'Royal William' begins with a period of dormancy where the plant rests, followed by germination from a seed or growth from a grafted specimen, depending on propagation practices. Once established, the plant enters a vegetative stage, growing stems, leaves, and roots. As it matures, it develops flower buds which bloom into the characteristic large, fragrant red roses of the 'Royal William' variety. After pollination, which can be done by insects or artificially, the flowers may produce hips containing seeds, though many cultivars are sterile and do not set viable seed. The plant then enters a period of senescence where flowers fade and leaves may yellow and drop, and prepares to enter another period of dormancy, often dictated by the colder winter months. This cycle can repeat annually, with proper care allowing the plant to live and bloom for many years.
PropogationPropogation time
Spring to early summer
Rosa 'Royal William', commonly known as 'Korzaun', is a hybrid tea rose that can be propagated most commonly by softwood cuttings. This method is typically done in late spring or early summer when new growth is mature enough to be still flexible but not too woody. Cuttings of about 6 to 8 inches (15 to 20 centimeters) are taken from healthy, disease-free plants, making sure they include several leaf nodes. The bottom leaves are removed, and the cut end could be dipped in rooting hormone to encourage root development. The cutting is then planted in a well-draining soil mixture, with the bottom half of the cutting submerged. Conditions must ensure high humidity and consistent moisture, but not waterlogged soil, as this can cause the cutting to rot. A plastic cover or dome can help maintain the appropriate environment for rooting, which may take several weeks.
