Methods of Aloe Propagation by Cutting
In home gardening, aloe is deeply loved for its unique shape and practical value. Many growers attempt to expand their aloe plantations through cutting propagation, but often fail due to improper operations. This article will systematically analyze the key steps of cutting propagation and provide a comprehensive care guide.
Five Core Elements of Aloe Propagation by Cutting
Optimal Time Selection
When the ambient temperature is stable between 18-25°C (April being the best), aloe cell activity reaches its peak. Research shows that the survival rate can reach 92% within this temperature range, while it drops sharply to 35% below 15°C.
Leaf Selection Criteria
Select the middle and upper leaves of 2-3-year-old mother plants, with a length of ≥8cm and thickness >1cm. Cut at a 45° angle using a blade sanitized with alcohol to maximize the cut area. Experimental data shows that leaves meeting these standards increase root growth speed by 40%.
Scientific Cut Treatment
Place the cut side up in a shaded, well-ventilated area until a semi-transparent callus forms (about 3-5 days). This process effectively prevents bacterial infection and promotes the secretion of rooting hormones, observed to increase the rooting rate by 60% after treatment.
Substrate Mixture Scheme
Use a golden ratio of珍珠岩:蛭石:粗砂 = 2:1:3, with a pH value controlled between 6.0-6.5. This structure ensures a porosity of 35% or more, maintaining both water retention and breathability, with comparative tests proving that root development time is reduced by 7 days.
Refined Management System After Planting
Light Control Strategy
Initially, place in a diffused light environment (light intensity ≤3000lux), and gradually increase light as new roots emerge. Use shade nets to adjust, ensuring 3-4 hours of soft light daily.
Temperature and Humidity Control
Maintain a day-night temperature difference of 5-8°C (day 25°C/night 20°C), with an air humidity of 70%-80%. Use a mist spray system to ensure the substrate moisture content remains between 30%-40%.
Nutrition Supplement Scheme
Do not fertilize during the rooting period (first 20 days), and apply a diluted rooting solution (1:2000) when new roots reach 2cm. Supplement with a foliar fertilizer containing calcium and magnesium monthly to promote cell wall development.
Through the above scientific methods, the rooting process can usually be completed in 25-35 days. Regularly observe the base status, and when white root tips break through the substrate, it indicates a successful establishment of an independent root system.
