What to Do When Succulent Roots Rot
Succulents, with their adorable appearance, have become the favorites of modern home greenery. However, the frustrating issue of root rot, which puzzles 70% of plant growers, is a significant headache during maintenance. This article systematically analyzes the prevention and treatment system for succulent root rot, guiding you through a comprehensive solution from prevention to rescue with six key steps.
Emergency Treatment Plan for Mild Root Rot
Three Elements of Water Control
When the initial symptoms such as soft leaves and yellowing bases are observed, immediately implement the three-step strategy of "stop watering - ventilation - loosening soil." It is recommended to use a red pottery pot with breathable holes at the bottom, combined with a mixed substrate with 40% perlite, which can increase the efficiency of accumulated water drainage by 60%.
Environmental Control Standards
Maintain an air circulation rate of >0.5m/s during the day and night. For north-facing balconies, it is suggested to install a mini circulation fan and run it for 3-4 hours daily. Avoid directing the airflow directly at the plant and use a wall reflection ventilation method to prevent leaf dehydration.
Surgical Guide for Severe Root Rot
Lesion Removal Specification
When more than 50% of the roots rot, a root resection is necessary. Use a curved forceps disinfected with alcohol, make an oblique cut 2mm from the edge of the healthy tissue, and apply a 2000-fold diluted carbendazim suspension to the wound surface. Note that the white vascular bundle tissue in the root center should be preserved, as it is key to regeneration.
Root Induction Technique
Water Induction Method: Fill a transparent container with 2cm of water, support the base of the plant with a grid, and maintain a 1-3mm air root contact space. For soil culture root induction, use a pure vermiculite substrate, combined with LED plant growth lights (wavelength 450nm), which can shorten the root induction period to 5-12 days.
Long-term Prevention Mechanism for Succulent Maintenance
Establish a "Three Checks and Three Controls" management system: check the potting soil pH value (ideal value 5.8-6.5) monthly, test the EC value (＜1.2mS/cm) quarterly, and replace the substrate annually. By using a smart soil moisture meter linked to an irrigation system, precise watering can be achieved. Remember, preventive maintenance is more important than emergency treatment!
