What Causes the Yellowing of Qian Chuan Zi Leaves
As a widely popular succulent potted plant, yellowing leaves are the most common problem encountered by plant enthusiasts. The golden yellow edges of the leaves are their characteristic feature, but when the entire leaf turns yellow extensively, it often indicates a deviation in the care routine. This article deeply analyzes the causes from four dimensions: light, water, nutrition, and provides actionable solutions.
Light Imbalance Causes Yellow Leaves
Analysis of Sunburn Symptoms
Although Qian Chuan Zi enjoys sunlight, direct sunlight in summer can cause leaf burn spots, initially appearing as yellow leaf tips, and in severe cases, the whole leaf surface turns white. In this case, immediately move the plant to a north-facing windowsill and use a shading net to filter 30% of the light intensity.
Light Recovery Plan
After moving, maintain good ventilation and mist the plant early and late every day to increase humidity. It is recommended to use a lux meter to monitor and control the light intensity between 15000-25000Lux. There is no need to remove the damaged leaves, as they will naturally be replaced by new leaves.
Essential Techniques for Water Management
Dry-Wet Cycle Judgment Method
Use the "Finger Joint Test Method": Insert the index finger into the potting soil up to the second joint, and water if the fingertip is dry. Maintain a watering cycle of 7-10 days in spring and autumn, shorten it to 5-7 days in summer, and extend it to 15-20 days in winter.
Steps for Waterlogging Treatment
When waterlogging is found at the bottom of the pot, immediately tilt the pot to pour out excess water. Use chopsticks to make air holes in the potting soil and place it in front of a fan to accelerate evaporation. For severe root rot, remove the plant from the pot, trim it, soak in carbendazim, and then replace with new soil containing 60% granules.
Scientific Proportion of Nutrient Supply
Principle of Light and Frequent Fertilization
Apply a balanced liquid fertilizer with nitrogen, phosphorus, and potassium once a month during the growing season, dilute the concentration to 1.5 times the standard specified in the instructions. Stop fertilizing in winter and pause during high summer temperatures above 35℃.
Accurate Iron Element Supplement
New leaves turning yellow between the veins are typical symptoms of iron deficiency. Dilute ferrous sulfate at a ratio of 1:2000, adjust the pH to 5.5-6.0 with citric acid, and slowly pour around the pot edge. Applying once every quarter yields the best results.
Systematic Maintenance Suggestions
In addition to the above specific treatments, it is recommended to replace the pot with a breathable red ceramic pot every spring, using a mixed substrate of akadama soil, volcanic rock, and decomposed leaf soil. Regularly rotate the pot to ensure even light exposure and use 101 Vitality Essence to enhance stress resistance. Through multi-dimensional maintenance adjustments, the plant can regain its bright, jade-like leaf color in 2-3 weeks.
