Method of Propagation for House Roll Calico
House Roll Calico, as a classic variety of succulents, is favored by gardening enthusiasts for its unique lotus seat shape and easy propagation characteristics. Mastering scientific propagation methods can not only increase the number of plants but also maintain the superior traits of the parent plant. This article systematically explains the practical points and maintenance tips of three mainstream propagation methods.
Core Techniques of Propagation for House Roll Calico
I. Cutting Propagation Operation Guide
1. Cutting propagation: Select a 5-7cm stem segment from the top of the plant that has grown too tall, cut diagonally at a 45° angle with a sterilized tool, and retain aerial roots for easier survival. After applying carbendazim to the cut surface, hang it in a well-ventilated area to dry for 2-3 days. It is recommended to use the hydroponic root induction method: place the stem segment 0.5cm above the water surface, change the water every 3-5 days, and transplant to a matrix of珍珠岩:蛭石=3:1 when 1cm white roots grow out.
2. Leaf propagation: Select healthy middle leaves, gently shake them off, and place them flat on the slightly damp surface of akadama soil, maintaining 70% air humidity and ventilating for 2 hours daily. Red buds can be seen after 30 days, and after the roots are fully developed, spray diluted HB101 vigor element at a ratio of 2000 times weekly to promote growth.
II. Advanced Tutorial on Division Propagation
In spring and autumn, select side buds with 3-4 leaves and separate them from the parent plant along the growth point using dental floss. Apply sulfur powder to the wound to prevent infection, and let it dry in the shade for 48 hours before planting. It is recommended to use porous red pottery pots with granular soil (wheat stone: deer swamp soil: peat = 5:3:2), avoid direct sunlight within 3 weeks after planting, use the immersion pot method to water, and maintain a matrix humidity of 30%.
III. Professional Seed Propagation Plan
Select seeds harvested in the current year and soak them in potassium permanganate solution for 20 minutes before sowing. The seedling soil needs to be disinfected at high temperatures and mixed in the ratio of peat soil: perlite: rice husk charcoal = 6:3:1, covered with 1mm thick vermiculite. Use the闷养 method to maintain a constant temperature of 25°C, open the lid for ventilation for 1 hour daily, and light green seedlings can be seen in 10-15 days. Use a 5000lux grow light for 14 hours daily during the seedling stage to effectively prevent overgrowth.
No matter which propagation method is used, the key to success lies in environmental control: maintain a day-night temperature difference of 8-10°C, air circulation rate greater than 0.3m/s, and apply a low-nitrogen, high-phosphorus potassium fertilizer (N-P-K=5-15-15) once a month during the growing season. Pay special attention to spraying mancozeb in advance during the plum rain season to prevent black rot disease. After 3 months of care, the new plant will show the characteristic silky texture of House Roll Calico.
