What to Do About Echeveria 'Tuyu Lian' Root Rot
Echeveria 'Tuyu Lian', a star in the succulent world of the Crassulaceae family, is adored for its unique curly leaf shape. However, during the care process, it often faces the crisis of root rot, which not only affects its ornamental value but also threatens the survival of the plant. This article will systematically analyze the full cycle solutions for 'Tuyu Lian' root rot from the root causes to emergency measures.
Analysis of the Three Main Causes of 'Tuyu Lian' Root Rot
Imbalanced Water Management
The leaves of 'Tuyu Lian' contain more than 85% water, making the principle of "completely dry before watering" crucial. It is recommended to water every 15 days in spring and autumn, and extend to every 30 days during the high-temperature dormancy period in summer. When monitoring soil moisture, insert a bamboo skewer 2/3 into the potting soil; if it comes out without any moisture marks, it's time to water.
Misconceptions in Container Selection
Experimental data shows that the breathability of red pottery pots is 47% higher than that of ceramic pots and 82% higher than that of glass containers. It is recommended to use unglazed pots with a diameter 3 cm larger than the plant, with 2-3 drainage holes at the bottom and a 3 cm thick layer of volcanic stones to enhance drainage.
Improper Environmental Control
The suitable growth temperature for 'Tuyu Lian' is between 15-25°C. When the temperature is above 30°C and the humidity is above 70%, the probability of root rot increases by 60%. It is recommended to use a thermometer and hygrometer for real-time monitoring, and to use a circulating fan to maintain air circulation.
Stage-by-Stage Treatment Guidelines for 'Tuyu Lian' Root Rot
Mild Root Rot Treatment Plan
Stop watering immediately when the bottom leaves become soft, remove the pot, and cut off the brown diseased roots, leaving the healthy white roots. Soak in a fungicide solution (Daconil 800x) for 20 minutes, then place in a shaded and well-ventilated area to dry the roots for 48 hours.
Severe Root Rot Rescue Measures
When the main root is completely black and rotten, make a 45-degree oblique cut 5 cm from the top. Apply rooting powder to the cut surface and insert it into a mixture of vermiculite and perlite (3:1). Keep the medium slightly moist, and it should root in about 15-20 days.
'Tuyu Lian' Root Care and Prevention System
It is recommended to use a soil mix with 70% particle soil: 3 parts Akadama, 2 parts鹿沼土 (鹿沼土), 1 part leaf mold soil, and 1 part rice husk charcoal. When repotting in spring every year, add 5-8 slow-release fertilizer granules to maintain nutrient supply. In winter, maintain 4 hours of direct sunlight per day, and use a shading net to filter strong light in summer.
By establishing a scientific watering cycle, choosing breathable containers, optimizing the growth environment with three-dimensional protection, and regularly checking the roots, the incidence of 'Tuyu Lian' root rot can be effectively reduced by 90%. Remember the principle of "better dry than wet" to keep this desert rose forever vibrant.
