How to Propagate Yulü Through Leaf Cutting
Yulü, as a highly ornamental variety in the succulent family, leaf cutting propagation is the most commonly used cultivation method by plant enthusiasts. With proper leaf handling and substrate matching, an 80% or higher survival rate can be achieved. This article will systematically explain the full process techniques from leaf selection to post-propagation care, accompanied by real-life operation photos to help you easily master the essentials of Yulü leaf cutting propagation.
Analysis of the Core Steps in Yulü Leaf Cutting
Leaf Selection and Handling Essentials
Select plump and healthy leaves from the middle and lower parts, hold the base of the leaf with a curved forceps disinfected with 75% alcohol, and gently rock it left and right until it naturally falls off. It is crucial to retain the complete growth point, as damaged leaves can become transparent and rot. Optimal operation is during spring and autumn when Yulü is in an active growth phase.
Critical Control of Wound Healing
Place the leaves in a cool and well-ventilated area for 48-72 hours, and the environmental humidity should be controlled below 50%. It is recommended to use a porous drying tray to lay the leaves flat, flipping them daily to check the scab formation. A thin layer of sulfur powder can be used as an alternative to myclobutanil to form a natural antibacterial protective layer.
Substrate Proportion and Disinfection
Use a golden ratio of 3:3:4 of red jade soil,鹿沼土 (Bokai soil), and vermiculite, with particle diameter of 2-3mm being optimal. Old soil must be sterilized with high-temperature steam, and new soil is recommended to be heated in a microwave at medium power for 5 minutes to kill germs. Maintain a substrate thickness of 5-8cm, and place陶粒 (ceramic stones) at the bottom to enhance drainage.
Scientific Method for Leaf Cutting
How to propagate Yulü through leaf cutting
Plant the leaf at a 30-degree angle half-buried in the soil, with the growth point lightly touching the surface of the substrate. Use a narrow-mouthed pot to slowly water around the pot edge, keeping the substrate slightly moist but not waterlogged. It is recommended to use a transparent seedling box to maintain 80% humidity, with 2 hours of ventilation daily to prevent mold.
Post-Propagation Care Strategies
During the rooting period (15-30 days), maintain a scattered light environment and keep the temperature between 18-25°C. When the new roots reach 2cm, apply a 2000 times diluted solution of Meininglu. When the bud diameter exceeds 1cm, gradually increase the duration of direct sunlight, with a transition period of about 2 months.
By precisely controlling temperature and humidity, scientifically mixing soil, and standardized operations, the success rate of Yulü leaf cutting can be significantly improved. It is recommended to adjust the care plan according to seasonal changes, and spring cuttings can form a complete plant shape in the same year. Master these core techniques, and you can also become an expert in succulent propagation.
