Propagation Methods of Spathiphyllum
As a representative of the Araceae family's ornamental foliage plants, Spathiphyllum is favored by many plant enthusiasts for its elegant white spathes and air-purifying properties. However, many plant lovers encounter propagation challenges: How to rapidly multiply Spathiphyllum? Actually, by mastering three propagation methods—division, seeding, and tissue culture, one can easily double the greenery. Below, we will thoroughly analyze the key points of each method to help you become an expert in Spathiphyllum propagation.
One, Division Propagation Method (Preferred for Home Use)
Best Operation Timing
It is recommended to perform this during March-May in spring or September-October in autumn when the temperature is stable at 18-25℃, which is conducive to new plants adapting to the pot. Choose mother plants that are over 2 years old, robust in growth, and have well-developed root systems, ensuring each plant has 3-5 complete leaves.
Division Steps
1. Stop watering 3 days before repotting, gently tap the pot wall to loosen the soil. 2. Rinse the roots until completely exposed and trim the rotting roots with a sterilized scissor. 3. Cut the rhizome along the natural branching point, retaining the complete aerial roots. 4. Apply charcoal powder to the wound for sterilization, let it dry in the shade for 30 minutes before potting.
Two, Seed Propagation Techniques
Seed Pretreatment
Obtain mature seeds through artificial pollination and soak them in 25℃ water for 48 hours, changing the water every 8 hours. It is recommended to use a mixture of perlite and peat soil (1:3) as the growing medium, which should be sterilized by steaming at high temperatures before use.
Intelligent Seedling Raising Method
1. Maintain a constant temperature of 25-28℃ during seeding. 2. Use the immersion method to water, maintaining 80% air humidity. 3. Use LED plant grow lights for 12 hours daily. 4. Spray with gibberellic acid solution (50ppm) once a week.
Three, Tissue Culture Technology
Professional Propagation Plan
Suitable for large-scale commercial production, this method requires establishing an aseptic operating room. Select young stem segments as the explants and use the MS medium formula with 6-BA (2mg/L) + NAA (0.2mg/L). Control the light intensity at 2000-3000 lux with a culture period of about 8-10 weeks.
No matter which propagation method is chosen, after transplanting the new plants, they should be placed in a diffused light environment for 2 weeks. Maintain an environmental humidity of over 70%, and applying potassium dihydrogen phosphate (1000 times solution) can promote root development. It is recommended to check the EC value of the growing medium monthly, keeping it between 1.2-1.8 mS/cm. Mastering these key points will allow you to easily achieve large-scale propagation of Spathiphyllum.
