Four-season Begonia Cutting Method
The four-season begonia is loved by gardening enthusiasts for its ability to bloom throughout the year, and cutting propagation is an important means to sustain its vitality. Scientific operations can achieve low-cost and efficient propagation. This article will break down the key points step by step, helping you master the core technology of asexual reproduction of four-season begonias.
Complete Guide to Four-season Begonia Cutting Process
Best Timing Selection
Scientific Cutting Treatment
Select semi-woody branches as cuttings, with a diameter of 3-5mm. Use a 45-degree oblique cut to increase the water absorption area, retaining the top two leaves with 1/3 pruning to reduce transpiration. Disinfect the cutting tools with 75% alcohol and apply charcoal powder to the cut ends to prevent infection.
Smart Matrix Formula
It is recommended to mix珍珠岩 (perlite): 蛭石 (vermiculite): 腐叶土 (decomposed leaf soil) in a ratio of 5:3:2, with a porosity of over 60%. Treat with high-temperature steam to avoid chemical disinfectant residues. Keep the matrix moisture at 40%-50%, with the best condition being able to form a ball when pinched and then easily fall apart when released.
Refined Cutting Operation
Use the plug cutting method with a spacing of 5cm×5cm. First, make holes with a bamboo stick to prevent cutting end damage, inserting to a depth of 1/3 of the cutting. Dip in an 800-fold solution of indole butyric acid, cover with a transparent dome to maintain 90% humidity, and ventilate for 15 minutes in the morning and evening.
Key Points for Post Cutting Care
After cutting, place in a diffused light environment with a constant temperature of 20-25°C, and roots will form in about 15-20 days. Gradually increase light after new leaves appear and use a nutrient solution with an EC value of 1.2-1.5mS/cm for top dressing. Transplant when the roots reach 5cm.
By precisely controlling temperature and humidity, choosing cuttings reasonably, and scientific care, the survival rate of four-season begonia cuttings can reach over 90%. This propagation method not only maintains the excellent traits of the parent plant but is also an effective means of large-scale production, worthy of further practice by gardening enthusiasts.
