What to Do About the Root Rot of Xue Zhi Ta
As a rare variety of succulent plants, Xue Zhi Ta is deeply loved by gardening enthusiasts for its unique pagoda-like shape. However, improper water control during maintenance often leads to root rot issues. This article will systematically analyze the causes and provide practical solutions to help you quickly save endangered plants.
In-depth Analysis of the Causes of Root Rot in Xue Zhi Ta
Water Management Mistakes Are the Primary Cause
The native environment of Xue Zhi Ta is dry with little rainfall, and its root system has the typical characteristics of desert plants: fleshy roots with strong water storage capacity but high respiratory needs. When the soil moisture exceeds 40% for 3 consecutive days, the roots will start to turn brown and rot. Especially during the plum rain season, using coconut bran substrates with high water retention increases the risk of waterlogging.
Improper Fertilizer Application Poses Hidden Dangers
Excessive nitrogen fertilizer is the main cause of fertilizer damage. Experimental data show that when the EC value exceeds 1.2mS/cm, new capillary roots will show burn symptoms within 48 hours. Fertilizing during the dormancy periods of winter and summer will also disrupt physiological balance and cause root rot.
Systematic Solutions for Root Rot in Xue Zhi Ta
Three Steps to Scientific Water Control
1. Use the 'Soak and Observe Method': Place the pot in a shallow water tray for 5 seconds and immediately remove it; if no water mark is seen at the bottom of the pot, water it. 2. Seasonal adjustment strategy: Spring and autumn 5-7 days/week, summer 10 days/week (at night), winter 15 days/week. 3. Substrate improvement formula: Red jade soil + volcanic rock + vermiculite in a 6:3:1 ratio, ensuring a permeability rate >85%.
Four Elements of Precise Fertilization
• Choose a special slow-release fertilizer for succulents (NPK=5-10-5) • Apply a 2000-fold diluted solution during the growing season monthly • Maintain ventilation within 72 hours after fertilization • Spray phosphorus potassium fertilizer on the leaves as an alternative to root topdressing
Emergency Treatment Full Process
If root rot is found, immediately remove the pot, cut off the brown roots with a sterilized scissor, and retain the healthy white root segments. After applying a fungicide powder to the wound, place it in a shaded area to air-dry the roots for 3-5 days. Use a new sterilized substrate for planting and keep it completely dry for the first week.
By establishing a dry-wet cycle system, implementing precise nutrient supply, and improving disease emergency response, not only can the existing root rot issues be effectively solved, but a long-term preventive mechanism can also be constructed. It is recommended to check the potting soil's breathability monthly and use smart soil testers to continuously monitor the EC value and water content, allowing Xue Zhi Ta to regain its layered green pagoda-like appearance.
