What to Do About Tang Shan Root Rot
Tang Shan, a classic variety of succulents, is widely loved for its unique fan-shaped leaves. However, improper environmental management during care can easily lead to root rot issues. This article will systematically analyze the causes of root rot and provide comprehensive solutions to help you save endangered plants.
Depth Analysis of the Causes of Tang Shan Root Rot
Double Threat of High Temperature and High Humidity
When the temperature exceeds 28℃, Tang Shan enters a dormant state, and its root absorption capacity drops sharply. If any of the following conditions are added: 1. Environmental humidity > 70% 2. Excessive soil moisture content 3. Poor air circulation, the roots will start to rot within 12-48 hours. It is recommended to use a thermometer and hygrometer for real-time monitoring.
Lethal Crisis of Rainwater Soaking
Although the combined potting has ornamental value, when placed outdoors: • Continuous rainfall during the plum rain season > 3 days • Clogging of the pot drainage holes • Overly strong water retention of the matrix, these triple risks can lead to prolonged soaking of the roots in water, which needs special attention during the rainy season.
Full Cycle Prevention and Control Plan for Tang Shan Root Rot
Four Elements of Environmental Control
1. Sun shading: Use 50% sun shading net in summer 2. Air circulation: Install a mini circulation fan 3. Matrix improvement: Add 50% particle soil 4. Watering rule: Use the pot immersion method to supply water, not more than twice a month
Five Steps of Emergency Treatment
Immediately after detecting root rot: ① Remove the pot and rinse the roots ② Disinfect the knife with alcohol ③ Cut off the discolored tissue ④ Apply carbendazim powder ⑤ Replant in moist soil after 3 days of drying in the shade
Long-Term Management of Tang Shan Care
It is recommended to check the root status every quarter, apply slow-release fertilizer in spring and autumn to enhance stress resistance. Using red pottery pots can increase breathability, and using the bamboo stake test method (observing moisture after inserting the matrix for 24 hours) can scientifically control watering.
Through environmental monitoring, scientific watering, and regular checks, a three-in-one management strategy can effectively prevent the recurrence of Tang Shan root rot and keep the plants vigorous and healthy.
