Cactus Cutting Propagation Method
Mastering the correct cutting propagation method is crucial for fast root growth and healthy development of cacti. As a representative drought-resistant succulent plant, cactus cutting propagation not only inherits the superior characteristics of the mother plant but also allows for experiencing the amazing process of plant propagation. This article provides a detailed explanation of cutting techniques applicable in all seasons through illustrations, helping beginners easily acquire this practical skill.
Core Techniques of Cactus Cutting Propagation
Best Time for Cutting Propagation
Although cacti can be propagated throughout the year, the success rate is highest when the temperature is stable at 20-25℃ during spring and autumn (March-May / September-October). At this time, the plants are in an active growth period, the incisions heal quickly, and roots can develop in 15-20 days. In winter, indoor care needs to maintain a temperature above 15℃, and in summer, avoid the strong midday sunlight.
Key Steps for Cutting Treatment
Select healthy 2-year-old stem segments and cut the cutting at a 45-degree angle using a knife disinfected with alcohol. The wound needs to be soaked in a carbendazim solution for 30 minutes for disinfection, then placed in a ventilated area to dry for 7-10 days to form callus tissue. This process effectively prevents black rot disease, increasing the survival rate to over 90%.
Scientific Cutting Propagation Operation Specifications
Use a mixture of perlite, vermiculite, and coarse sand in a ratio of 1:1:2, and preprocess the mixture by sunning and disinfection. Insert the cutting into the matrix to a depth of 1/2, keeping it upright. After watering thoroughly for the first time, place it in a scattered light environment, do not water for 7 days, and maintain the air humidity at around 60% with a spray bottle. Gradually increase the duration of sunlight after new buds sprout.
After mastering the three core points, you can try the hydroponic cutting method: suspend the treated cutting 1 cm above the water surface, using the moisture to induce root growth. This method speeds up root growth by 5 days compared to soil culture, especially suitable for epiphytic cactus varieties such as蟹爪兰 (Schlumbergera truncata).
