How to Pot newly purchased Phalaenopsis orchids
As a highly ornamental species among tropical orchids, Phalaenopsis orchids have become a new favorite indoor green plant with their elegant flower posture. However, newly purchased plants often experience growth stagnation due to improper transplantation. Mastering scientific potting methods and care essentials can help Phalaenopsis orchids quickly adapt to the new environment and continue to thrive.
Complete Process Analysis of Transplanting and Potting Phalaenopsis Orchids
Depotting and Root Pruning
Use a disinfected scissor to cut along the edge of the plastic pot, retaining the complete root mass. Carefully remove the moss matrix wrap, avoiding mechanical damage. Focus on the aerial roots: use forceps to remove decayed roots and retain plump roots. It is recommended to soak in a 50% carbendazim solution (800 times) for 10 minutes for disinfection, and then let it dry to half before use.
Golden Ratio for Matrix Configuration
Use the sandwich layering method: the bottom layer is covered with 3cm of pine bark chips (diameter 1-2cm), the middle layer uses a mixed matrix of fermented bark:moss = 2:1, and the top layer is covered with live moss. All materials need to be sterilized with high-temperature steam to ensure a sterile state.
Scientific Planting Operation Standards
Choose transparent plastic pots for better observation of the roots. When planting, keep the pseudobulb exposed 1/3 above the matrix, with the aerial roots coiled spirally. After filling the soil, gently tap the pot wall to let the matrix settle naturally, avoid over-tightening that affects air permeability.
Adapting to the Environment and Continuous Care for Phalaenopsis Orchids
Environmental Regulation During the Acclimatization Period
For the first two weeks, maintain diffused light (≤3000lux) and air humidity of 70%-80%. It is recommended to use a thermometer and hygrometer to monitor, and use a humidifier to maintain a stable environment. Do not fertilize at this stage, and spray the leaves with water every 3 days to supplement moisture.
Accurate Management of Light Intensity
In spring and autumn, expose to 2 hours of gentle morning light (about 8000lux), and use a sunshade net to filter 60% of the light in summer. In winter, increase to 4 hours of direct sunlight, and use LED grow lights to maintain a 12-hour/day light cycle.
Smart Water and Fertilizer Management System
Follow the "dry-wet" principle, water the pot when the surface of the matrix turns white. Apply a balanced 20-20-20 NPK fertilizer (2000 times solution) every half month during the growing period, and switch to high-phosphorus and potassium fertilizer during the flowering period. It is recommended to use an EC pen to monitor the matrix salt content, and flush the matrix when the EC value is greater than 1.2mS/cm.
Through systematic potting operations and environmental regulation, the survival rate of Phalaenopsis orchids can reach 95% or more. Regularly observe the leaf condition (ideal leaf temperature 18-28℃) and adjust the care strategy in a timely manner, which can keep the plant growing for 3-5 years. It is recommended to replace the matrix every 2 years and combine division to achieve sustainable cultivation of Phalaenopsis orchids.
