What to Do About Root Rot in Nocturne City
Nocturne City, as a star variety among succulents, is beloved by gardening enthusiasts for its upright株型 and unique ornamental value. However, improper management during care often leads to root rot issues, and if not addressed promptly, the entire plant will wither. This article will systematically analyze the causes of root rot in Nocturne City and provide a practical rescue plan.
Nocturne City Root Rot Diagnosis and Cause Analysis
Root Rot Caused by Improper Water Management
Succulent roots are extremely sensitive to water. In summer, keep the soil slightly moist but avoid waterlogging, and follow the "dry-wet" principle in spring and autumn. It is recommended to use a graduated尖嘴 watering壶, controlling each watering to one-third of the pot's volume, and not exceeding two waterings per month in winter. Use a bamboo skewer to test the soil moisture, and water only when the skewer is dry after being pulled out.
Root Burn Caused by Fertilizer Application Mistakes
During the growing season (March-May, September-November), apply a diluted 300-fold nitrogen-phosphorus-potassium compound liquid fertilizer monthly, with the addition of composted sheep manure pellets for better results. Stop fertilizing completely during the high-temperature dormant period (June-August) and winter (December-February) to avoid fertilizer buildup causing root burn. It is suggested to perform a "rewatering" operation the day after fertilizing, which is to rinse the remaining fertilizer on the surface of the substrate with clean water.
Improper Choice of Cultivation Substrate
It is recommended to use a golden ratio substrate: 40% red jade soil + 20% volcanic rock + 20% decomposed leaf soil + 20% perlite. When repotting in spring, place a 3cm thick layer of陶粒 drainage at the bottom of the pot, fill the middle layer with mixed substrate, and cover the top with 0.5cm of maifan stone granules. Regularly loosen the soil with a bamboo chopstick to maintain the substrate's breathability and prevent compaction.
Systematic Rescue Plan for Nocturne City Root Rot
Early Identification and Diagnosis Techniques
Observe whether the base of the plant shows signs of transparency or softness, and check stability by gently shaking the plant. Healthy roots should be milky white and elastic, while rotten roots are brown and slippery. It is recommended to inspect the roots quarterly and remove dead roots with a pair of tweezers that have been sterilized with alcohol.
Professional-Level Rescue Operation Procedure
① Trim the rotten roots after removing the pot, leaving at least 5cm of healthy main root; ② Apply a mixture of mycillin and root stimulant to the wounds; ③ Hang the plant in a shaded, well-ventilated area to dry the roots for 3-5 days; ④ Repot using new sterilized substrate; ⑤ Avoid watering for two weeks, maintaining humidity through foliar spraying.
Nocturne City Daily Care Golden Rules
Ensure 4 hours of scattered sunlight daily, and use a lux meter to monitor and ensure the light intensity is between 8000-12000 lux. Maintain the environmental temperature within 15-28°C and keep the air humidity between 40%-60%. It is suggested to set up a care log, recording the plant's growth status regularly and adjusting the care plan in a timely manner based on comparative data. Plants that have been successfully treated should be isolated and observed for one month before being reintegrated into the normal care sequence.
