What to Do If the Epipremnum Aureum Dies in Winter
Severe cold is the season when Epipremnum aureum is most susceptible to freezing. When you notice that the plant's branches and leaves turn black and wilt, taking timely scientific rescue measures can help the damaged Epipremnum aureum regain vitality. This article will systematically analyze the complete revival plan for Epipremnum aureum after frost injury, from root treatment to transplantation and care.
Ⅰ. Frost Damage Root Rescue
1.1 Soil Loosening Techniques
Gently tap the pot wall to loosen the soil, and use a gardening spade to completely remove the root ball from the edge of the pot. Rinse with running water at a temperature of about 20°C to avoid secondary freezing. Black decayed roots should be trimmed immediately, leaving healthy roots with white rootlets.
1.2 Root and Stem Selection Criteria
Choose stems that are bright green and have full nodes, with a diameter greater than 3mm for higher survival rates. Pay attention to check if there are dormant buds at the node, which is the key position for new bud germination.
Ⅱ. Division Regeneration Operation Guide
2.1 Scientific Cutting Techniques
Use pruning shears that have been sterilized with alcohol, and cut the stems at a 45° angle. Keep 2-3 aerial root nodes on each segment and apply carbendazim powder to the cut surface to prevent infection.
2.2 Substrate Preparation Points
Use a sterile substrate of peat soil: perlite in a ratio of 3:1, and add a small amount of vermiculite to enhance water retention. Place a 3cm thick layer of ceramsite at the bottom of the pot as a drainage layer to prevent waterlogging and secondary rot.
Ⅲ. Full Process of Revitalization Care
3.1 Environmental Control Strategies
Maintain a constant temperature of 18-25°C and use a humidifier to keep the air humidity at 60%. Perform shading treatment for the first two weeks, and gradually increase scattered light after new buds have emerged.
3.2 Water and Fertilization Management Plan
Use the pot immersion method to replenish water, soaking for 2 minutes every 7 days. After the new leaves have unfolded, apply 1/4 concentration of foliage plant nutrient solution, combined with brassinolide to promote root development.
Through systematic post-freezing treatment, about 60% of damaged Epipremnum aureum can recover growth vitality within 45 days. It is recommended to take preventive measures in advance during winter, such as using pot-in-pot insulation and reducing watering, to help Epipremnum aureum survive the winter safely.
