Tangyin Leaf Propagation Tutorial
As a classic succulent variety of the Sedum genus in the Crassulaceae family, Tangyin is deeply favored by gardening enthusiasts for its flame-like leaf color and robust vitality. Leaf propagation, being the most economical and efficient method of succulent reproduction, can help friends quickly expand their Tangyin family. This article will illustrate the entire process of leaf propagation through five core steps, helping you easily master the secrets of succulent propagation.
Preparation Before Leaf Propagation
Best Time for Cutting Selection
In spring and autumn (March-May / September-October) when the average daily temperature is 18-25°C, plant cell activity is the strongest. Leaf propagation at this time can result in root growth 40% faster than in summer and effectively avoid the僵 seedling phenomenon caused by low winter temperatures.
Leaf Selection Criteria for Parent Plant
Choose middle-layer healthy and plump leaves: the bottom old leaves are not active enough, and the top new leaves are not fully mature. Use a curved forceps disinfected with alcohol to hold the leaf and shake it left and right until a slight "click" sound is heard, indicating the successful removal of the complete growth point.
Complete Process of Leaf Propagation Operation
Wound Treatment Techniques
Place the leaf in a shaded and well-ventilated area for 2-3 days to allow the cut to form a semi-transparent healing tissue. Then, apply a thin layer of cinnamon powder (a natural fungicide) instead of traditional wood ash, which can prevent bacteria and is rich in root-promoting elements.
Substrate Formula Optimization
Mix in the ratio of Perlite: Vermiculite: Peat soil = 5:3:2 and disinfect in a microwave oven at high temperature for 3 minutes. This structure can ensure breathability and maintain moderate water retention, increasing the rooting rate by 25% compared to a single river sand.
Demonstration of Flat Rooting Method
Insert the processed leaf at a 30° angle on the surface of the substrate, with the leaf back facing down for easier root germination. Maintain a 2cm spacing to avoid crowding and spray water to make the substrate slightly damp (water content about 30%).
Scientific Maintenance During Rooting Period
Key Points of Environmental Control
Place it in a bright area with scattered light, maintaining a 50% shading rate. Use the bottom dipping method to water, supplementing a small amount of 101 Vitality every 5 days, which can promote root germination 3-5 days earlier.
Signs of Successful Rooting
About 15-20 days later, red villous root points appear at the base of the leaf. At this time, gradually increase the lighting to 4 hours a day and use Melanure 2000 times liquid to promote rapid root development.
Post-Transplant Management
When the new seedlings reach a diameter of 2cm, transfer them with the parent leaf into a 7cm diameter red pottery pot. Use 70% granular soil for cultivation, following the "dry and wet" principle, and you can get a strong mature plant after half a year.
By precisely controlling temperature and humidity and scientifically mixing soil, the success rate of Tangyin leaf propagation can reach over 90%. Mastering the three keys of parent leaf selection, wound treatment, and root promotion techniques can even allow gardening beginners to enjoy the fun of succulent propagation. It is recommended to alternate with cutting propagation to quickly achieve a full pot effect.
