What to Do When the Roots of a Large Pot of Epipremnum Aureum Rot
As a common ornamental leaf plant, the health of the roots of Epipremnum aureum directly affects the survival of the plant. When the leaves turn yellow and the branches wilt, it often indicates that the roots have been damaged. This article systematically explains the operation specifications and precautions for the rescue process and maintenance points after root rot.
Urgent Treatment Plan for Rotting Roots of a Large Pot of Epipremnum Aureum
1. Precision Pruning Process of Roots
After removing the plant from the pot, all brown soft rot roots need to be cut with a sterilized scissor, leaving only the white healthy rootstocks. Focus on cleaning the decayed tissue at the rootstock connections to avoid cross-contamination. After pruning, rinse the residual soil thoroughly with running water and place it in a ventilated area to dry for 4-6 hours.
2. Key Steps for Disinfection and Sterilization
Soak the processed roots in a 0.1% potassium permanganate solution for 3 minutes, or use a fungicide solution of carbendazim at 800 times for 15 minutes. After disinfection, it needs to be dried a second time until the cut ends are completely healed, which can effectively block the transmission route of fungi.
3. Key Points for Potting Mix Configuration
It is recommended to use a mixed medium of peat soil: perlite: coconut bran = 5:3:2, mixed with an appropriate amount of decomposed pine phosphate to increase aeration. A 3cm layer of陶粒 (ceramic balls) should be placed at the bottom of the pot for drainage. When filling the new soil, make sure to keep it loose and avoid pressing it too hard.
Guide to Potting and Watering Maintenance for Rotting Roots of Epipremnum Aureum
1. Timing for Water Management
The first watering after planting should use a root stimulant, pouring it slowly around the edge of the pot until water seeps out from the bottom. Maintain the medium moisture at 40%-50%, using the finger test method: if the second knuckle of the finger inserted into the soil feels dry, add water. In summer, water early in the morning, and in winter, change to around noon.
2. Three Elements of Environmental Control
Control the light intensity between 8000-12000 lux and avoid direct strong sunlight. Maintain the temperature between 18-28℃ and keep the humidity above 60%. It is recommended to use a thermometer and hygrometer for real-time monitoring and adjust the microenvironment with a humidifier.
3. Indicators for Root Recovery Observation
The emergence of new leaves is an important signal of root recovery, usually appearing 2-3 weeks after treatment. If no new buds grow after 20 days, the root condition needs to be rechecked. Apply a diluted 2000 times HB-101 plant vitalizer every month to promote recovery.
Through scientific root treatment and precise post-maintenance, the survival rate of a large pot of Epipremnum aureum can be increased to over 85%. It is recommended to check the root health every quarter, regularly replace the medium, and prevent the recurrence of root rot problems from the root cause.
