Spring Foal Leaf Cutting Method
The unique morphological characteristics of Spring Foal have made it a focus of attention for succulent enthusiasts. Many growers have tried to propagate it using leaf cutting but have failed repeatedly. This article will delve into the correct method of propagating Spring Foal, revealing the secrets of efficient propagation for this leafless plant.
Core Propagation Method Analysis of Spring Foal
Why Leaf Cutting is Not Feasible
The surface of Spring Foal plants does not have a true leaf structure, and the spiky projections covering the succulent stems lack the growing points required for leaf cutting. Experimental data show that the success rate of using stem cuttings can reach 85%, while the survival rate of leaf cutting is less than 3%. It is recommended to cut 10cm healthy stem sections from May to September (avoiding extreme high temperatures), let the cut surfaces dry, and then insert them into a mixture of vermiculite and perlite (3:1). Maintain an environmental temperature of 20-25°C.
Three Efficient Propagation Techniques
Seeding Propagation Steps
Select mature seeds with a diameter of 0.5-1mm and use a matrix of peat soil: coarse sand in a ratio of 2:1. After sowing, cover with 2mm fine vermiculite and use the immersion method to water. Maintain a day-night temperature difference of 10°C (day 25°C/night 15°C), and seedlings can be seen in about 15-20 days.
Key Points of Grafting Technique
Select the same genus of rootstock (such as Euphorbia) and use the flat joint method. Cut a 30°斜面 at the base of the Spring Foal stem section, and make a corresponding cut on the rootstock. Use a plant grafting clip to secure it, place it in a scattered light environment for 7-10 days, and gradually increase light after callus formation.
Best Time for Division
When the diameter of the daughter plant reaches 1/3 of the mother plant (about 3-5cm), separate it using a sterilized tool. Apply charcoal powder to the cut surface to prevent bacteria, and let it sit for 3 days before planting. Keep the matrix slightly moist for the first two weeks after division and avoid direct sunlight.
