Method of Water Propagation for Chinese Roses
Water propagation is an efficient seedling-raising method commonly used by Chinese rose enthusiasts. By scientifically transitioning from hydroponics to soil cultivation, it can significantly improve the survival rate of seedlings. This article explains the key techniques of water propagating Chinese roses, along with the original double-cup water-saving method, making it easy for beginners to master the entire process from branch handling to successful potting.
Essential Tools and Substrate Selection
Must-Have Materials List
• Sterile garden soil mixed with vermiculite (1:1) as a substrate • Double-cup system: two transparent plastic cups used together • Auxiliary tools: sterilized scissors, root powder solution
Optimizing Branch Treatment
Golden Standard for Rooting
When the water roots reach 3-5 cm and secondary lateral roots appear, it is the best time for transplantation. Retain the top two compound leaves for photosynthesis, and the rest of the leaves should be cut obliquely at the base of the petiole to reduce the transpiration area.
Double-Cup Transplanting Technique

Substrate Filling Skills
Place a 2cm layer of coal cinders at the bottom of the inner cup, then fill the substrate to 1/3 and add water. Using the principle of water pressure buffering, slowly add sterile soil under the protection of the outer cup to ensure that the roots naturally spread without damage.
Water Control and Maintenance Tips
After removing the outer cup, the inner cup's permeable holes form a progressive drainage system. Keep the environment shaded for the first 48 hours, on the third day start with scattered light induction, and supplement diluted seaweed fertilizer weekly to promote root development.
Master the three elements of water propagation for Chinese roses - appropriate timing, scientific water control, and progressive lighting, and the survival rate can reach over 90%. It is recommended to supplement with chelated iron fertilizer monthly to prevent yellow leaves. After 60 days, you can see plump new buds sprouting, achieving a seamless transition from hydroponics to soil cultivation.
