What to Do About Mingyue Root Rot
Mingyue, a star variety among the景天科 (Sedum) succulents, is loved by gardening enthusiasts for its yellow-green gradient leaves. However, during the maintenance process, the plant often wilts due to root problems. This article will systematically analyze the causes of root rot and provide a practical rescue plan to help you regain a healthy Mingyue.
Depth Analysis of the Causes of Mingyue Root Rot
Misunderstandings in Potting Soil Medium Configuration
Mingyue prefers loose and breathable sandy soil in its native environment. It is recommended to use a golden ratio of 60% akadama soil + 30% perlite + 10% decomposed leaf soil. The potting soil should be changed every 2 years, and the amount of bone meal should be controlled within 5% of the total mass. Excessive organic matter will accelerate soil compaction.
Key Points for Watering Rhythm Control
In the spring and autumn growing seasons, it is recommended to water thoroughly every 7-10 days, extend to 15 days during the high-temperature summer, and completely stop watering in the low-temperature winter. The bamboo stake test method can be used to judge: insert a bamboo stake into the potting soil for 2 hours, and if only the tip 1cm is slightly moist, it is the best time to water.
Three-Level Rescue Plan for Mingyue Root Rot
Process for Mild Rot Treatment
If early symptoms (wrinkled leaves/basen blackening) are found, immediately remove the plant from the pot. Use a sterilized pair of scissors to remove the discolored roots, leaving only the healthy white rootlets. After applying a fungicide powder to the wound, place the plant in a well-ventilated area to air-dry the roots for 48 hours, then replant using moist soil.
Rescue Strategy for Severe Rot
When the main root is completely blackened, stem cutting needs to be performed. Choose a healthy stem 5cm from the top, leaving 3-4 intact leaves. After dipping the cut in rooting powder, use pure vermiculite for cutting. Keep the medium slightly moist, and new roots can sprout in about 15 days.
Technique for Reusing Healthy Leaves
Healthy leaves can be placed flat on the surface of perlite, maintaining 60% air humidity. Expose to 3 hours of scattered light daily, and when the red root point appears at the leaf stalk, transplant it to a seedling pot. Remember to rotate the container weekly to ensure the new buds grow upright.
By regularly observing the plant's condition (check the roots monthly), scientifically preparing the soil (add volcanic rock to enhance aeration), and precisely controlling water (use a moisture meter to monitor), you can effectively prevent root rot recurrence. Mingyue has a strong vitality, and as long as the correct maintenance methods are mastered, even if affected by root rot, it can be renewed.
