The Cultivation Method of Kushui Rose
As a unique Rosaceae plant in the northwest, Kushui rose is favored by horticulture enthusiasts for its distinctive flower shape and rich aroma. This drought-resistant shrub not only has ornamental value but is also an important raw material for essential oil extraction. Mastering scientific cultivation methods can make the plant grow robustly and achieve year-round fragrance.
Key Elements of Environmental Control
Temperature and Light Management
The ideal growth temperature should remain stable between 15-28°C. When temperatures exceed 32°C in summer, ventilation should be enhanced to cool down. In winter, in the northern regions, it is recommended to use double protection: cover the ground-planted plants with 3cm thick pine needles, and move the potted plants into a room above 5°C. Ensure 5 hours of scattered light daily, and filter 30% of the strong light at noon in midsummer using a shading net.
Water Supply Rhythm
Adopt the 'dry-wet' irrigation principle, watering thoroughly every 3 days in spring and autumn, and spraying morning and evening in summer. Maintain soil moisture at 60% during the bud differentiation period, and check by inserting a bamboo skewer: if the top 2cm of the soil is dry, water promptly. During the rainy season, dig drainage ditches to prevent waterlogging and root rot.
Nutrition Management Plan
Fertilizer Ratio Selection
Use a base fertilizer of decomposed sheep manure and bone meal mixed in a 3:1 ratio, applying 5kg per square meter. During the growing season, apply phosphorus-potassium fertilizer every 15 days, recommend using rose-specific fertilizer (N-P-K=5-10-10) diluted 1000 times for root irrigation. Add borax solution (0.1% concentration) during the bud formation stage to enhance flowering quality.
Plant Shape Control
Scientific Pruning Techniques
Perform shaping pruning before spring sprouting, retaining 5-7 main branches at a 45° angle. After flowering, promptly remove the spent flowers, leaving 2-3 buds at the base. Every winter, thin the dense branches to maintain a central openness rate of over 40%. Pruning tools need to be disinfected with 75% alcohol, and the cuts should be涂抹ed with a healing agent.
Efficient Propagation Methods
Hardwood cutting is done in mid-March, selecting 1-year-old branches with a diameter of 0.8cm, cut into 15cm sections with 3 buds. Prepare the matrix with珍珠岩: peat soil = 1:2, soak the base in ABT rooting powder 200ppm before insertion. Maintain 80% humidity, and the roots can be transplanted after 45 days.

Health Protection System
Comprehensive Disease Control
Before the rust disease outbreak, spray 25% triazole ketone wettable powder 800 times liquid, with a 10-day interval for 3 consecutive times. Immediately remove and deeply bury any diseased leaves. Use Bordeaux mixture (1:1:200) on the whole plant for prevention before the rainy season.
Ecological Pest Control
During the爆发 period of aphids, hang yellow sticky traps, with 2 per square meter. Use black lights at night to lure and kill adult golden beetles. Biological control can release ladybugs (5-8 per plant) for ecological regulation.
Through systematic maintenance and management, Kushui rose can bloom 3-4 times a year, with a single plant yield increasing by over 40%. Regularly observe the plant's condition, adjust maintenance strategies based on the phenological period, and create courtyard landscape highlights while obtaining high-quality flower material. It is recommended to establish a maintenance log, recording key data such as temperature and fertilization, to form a personalized cultivation plan.
