Detailed Explanation of Rose Water Cutting Propagation Method
Rose water cutting propagation is a popular soilless cultivation technique in recent years, which promotes root formation of branches in a hydroponic environment and features simple operation and high survival rate. This article provides a detailed analysis of the complete process of rose hydroponic cutting through real-time illustrations, guiding you from branch selection to transplantation and planting, helping you master the essentials of water cutting propagation easily.
I. Branch Selection and Treatment
1.1 Best Material Collection Time
Select semi-woody branches of the current year in spring and autumn (March-April / September-October), as the branches are active and nutrient-rich at this time. Avoid using tender branches or fully lignified old branches, as the former is prone to rot and the latter has slow root formation.
1.2 Scientific Pruning Techniques
Retain 2-3 stem nodes, leaving 1-2 compound leaves at the top for photosynthesis. Use a flat cutting method to cut 0.5 cm below the node, ensuring a smooth cut without burrs. Control the total length of the branch to 10-15 cm, and maintain a water depth of 3-4 cm when inserting into the foam board.
II. Light and Temperature Control
2.1 Seasonal Light Management
In spring and autumn, expose to full sunlight, and in summer, use a shading net to filter 50% of the light. Maintain the water temperature at 18-25°C, and if it drops below 15°C in winter, move it to the side of the indoor window and use LED lights to maintain a light intensity of 2000-3000 lux.
III. Key Points for Water Quality Maintenance
3.1 Water Replacement Cycle and Techniques
Use tap water that has been exposed to sunlight for 3 days, replace the water every 72 hours, and clean the container. During the high-temperature period of summer, add 1 piece of activated carbon to purify the water quality, replenish water in time when the water level drops, and always keep the cut end fully submerged.
IV. Rooting Judgment and Transplanting
4.1 Signs of Successful Rooting
After 15 days, observe the formation of white callus at the cut, and after 30 days, you can see 3-5 cm white new roots. If the cut turns black, discard it immediately to avoid infecting healthy branches. When the roots reach more than 5 cm, transplant with a mixture of perlite and nutrient soil.
Through systematic water cutting management, the survival rate of rose cutting can reach over 85%. Mastering key technical points such as light adjustment and water quality maintenance, combined with seasonal maintenance strategies, even gardening beginners can successfully achieve rose hydroponic propagation. It is recommended to regularly observe the condition of the branches and adjust the maintenance plan in a timely manner to enjoy the unique pleasure of hydroponic plant growth.
