What to Do When the Leaves of Biyu Lian Turn Yellow and Soften
As a standout in the succulent family for its beauty, Biyu Lian is deeply loved by flower enthusiasts for its jade-like flesh leaves. However, when the leaves gradually turn yellow and soften, it often leaves caretakers at a loss. This article will analyze the causes of leaf abnormalities from four core dimensions and provide actionable solutions.
One: Yellow Leaves Caused by Light Imbalance
1.1 Identifying Symptoms of Insufficient Light
Biyu Lian requires 4-6 hours of scattered light daily. Long-term placement in a dark environment can hinder photosynthesis and lead to chlorophyll loss. Initial symptoms include leaves turning pale and yellow, and in severe cases, there may be excessive growth of stems, and leaf wrinkles.
1.2 Techniques for Scientific Light Supplementation
In spring and autumn, it can receive full sunlight, while from 10:00 to 15:00 in summer, strong light should be filtered using a shading net. In winter, it is recommended to use a grow light for 2 hours daily, with the lamp maintaining a distance of 30-40cm from the plant.
Two: Key Points for Water Management
2.1 Water Control Plan During Dormancy
When the temperature consistently exceeds 30°C, Biyu Lian enters a dormant state. During this period, watering should be completely stopped, and a humidity level of 50% should be maintained using an air humidifier. Incorrect watering can lead to root suffocation, causing the base leaves to soften first.
2.2 Watering Schedule During Growth Period
During the peak growing seasons of spring and autumn, the "soak pot" method should be used to water: immerse the pot in 2cm of water every month, and remove it after 10 minutes to drain. Ensure that the leaf heart does not accumulate water to prevent gray mold disease.
Three: Optimization Strategies for Substrate Ratio
3.1 Golden Soil Mixing Formula
Mix particle soil, peat soil, and vermiculite in a ratio of 5:3:2, and add 5% bone meal to enhance calcium content. Every spring, when repotting, old compacted soil should be thoroughly removed, and decaying fine roots should be pruned.
3.2 Guide for Choosing Pots
It is recommended to use red clay pots or rough clay pots, with a diameter 3-5cm larger than the plant's canopy. The bottom must have three or more drainage holes, and a 2cm thick layer of ceramsite should be placed to enhance breathability.
Four: Environmental Control System Solution
4.1 Building a Stereoscopic Ventilation System
Install a circulating fan to run for 3 hours daily to maintain air circulation. For balcony care, set up a立体 flower stand, keeping the distance between plants at least 15cm to avoid leaf overlap.
4.2 Synergistic Control of Temperature and Humidity
Use a thermometer and hygrometer to monitor, aiming for an ideal environment of 25°C during the day and 18°C at night, with humidity between 40-60%. In summer, place water trays to cool through evaporation, and avoid contact with radiators in winter.
By systematically adjusting the four elements of light, water, substrate, and environment, 90% of yellow leaf issues can be improved within 2-3 weeks. It is recommended to check the leaf condition monthly and keep a maintenance log to record growth changes. Mastering these techniques will ensure that your Biyu Lian can regain its healthy, jade-like luster.
