What to Do When Ardisia crenata Leaves Turn Yellow and Droop? Causes and Solutions
Friends who love flowers and plants have all heard of Ardisia crenata, but many friends do not know how to grow it. What should we do if the leaves of Ardisia crenata turn yellow? Ardisia crenata is evergreen all year round. When we grow Ardisia crenata in daily life, the leaves will show a drooping phenomenon. So what causes this phenomenon, and how should we solve it?
What to Do When Ardisia crenata Leaves Turn Yellow
1. Because the watering frequency is too high; if the leaves of Ardisia crenata turn yellow due to watering, you need to loosen the soil in time and stop watering, and wait until the soil surface turns slightly white before watering again. As long as the soil feels moist, do not water. You should water thoroughly only after the surface soil looks dry. It likes light, so do not place it in a location without light.
2. Because the temperature is low and Ardisia crenata has been frozen, do not place it under conditions with too high a temperature for now; 10-15°C is sufficient. After 10-15 days, gradually raise the temperature or maintain the current condition. When the outdoor temperature is suitable, it is better to care for it outdoors.
3. If the yellowing is caused by pests, then it is necessary to spray insecticide to kill the pests.
Causes and Solutions for Drooping Leaves of Ardisia crenata
1. Causes of drooping leaves in Ardisia crenata
1. Bacterial wilt: The main manifestation of bacterial wilt is that the plant above ground shows no abnormality, but during the day it suddenly loses vitality, the aboveground part withers, and the stems and leaves remain green. This process is relatively rapid. First, the roots become diseased and rot, and then it gradually invades upward.
2. Drought: Because Ardisia crenata is not drought-tolerant, when growing it, if watering is insufficient and it is kept too dry for a long time, it will cause the leaves to dry and scorch. Of course, this does not only refer to not watering for a long time. When watering only halfway, it is also easy to cause the root system of Ardisia crenata to lack water, and the leaves to dry, scorch, and droop.
2. Solutions
1. Bacterial wilt is likely to occur under conditions of high temperature and high humidity, with the soil not being changed for a long time, soil compaction, or excessive watering and excessive application of nitrogen fertilizer. Therefore, first of all, preparations should be made in terms of the growing environment to avoid the above unfavorable conditions. If bacterial wilt occurs, it is necessary to spray streptomycin in time for prevention and control.
2. If the leaves of Ardisia crenata dry, scorch, and droop due to drought, watering must be sufficient and reasonable. Pay attention to maintaining a state where the soil is moist but not waterlogged. When watering, it must be watered thoroughly.
Cultivation Techniques for Ardisia crenata
1. Humidity management
It likes a humid or semi-dry climate environment and requires the relative air humidity of the growing environment to be 50-70%. When the relative air humidity is too low, the lower leaves turn yellow and fall off, and the upper leaves lose their luster.
Temperature management: Because it originates from subtropical regions, it has strict requirements for winter temperature. When the ambient temperature is below 8°C, growth stops.
2. Light management
It has a strong ability to adapt to light. When caring for it indoors, try to place it in a place with bright light, such as a well-lit living room, bedroom, study, and other places. After caring for it indoors for a period of time (about one month), move it outdoors to a shaded place (with insulation conditions in winter) for a period of care (about one month), and alternate back and forth in this way.
3. Fertilizer and water management
①. For potted plants, in addition to adding organic fertilizer when potting, proper fertilizer and water management should also be carried out during usual care.
②. Spring, summer, and autumn: These three seasons are its peak growth seasons. Fertilizer and water management follows the cycle of "Huabao"--clear water--"Huabao"--clear water, with an interval of about 1-4 days.
③ Winter: During the winter dormant period, the main task is to control fertilizer and water well. Fertilizer and water management follows the cycle of "Huabao"--clear water--clear water--"Huabao"--clear water--clear water, with an interval of about 3-7 days.
④ For field-planted plants, in spring and summer, according to drought conditions, apply fertilizer and water 2-4 times: first open a small circular trench 30-100 cm outside the root collar (the larger the plant, the farther from the root collar), with the trench width and depth both 20 cm. Sprinkle 25-50 jin of organic fertilizer into the trench, or 1-5 liang of granular compound fertilizer (chemical fertilizer), and then water thoroughly. After winter begins and before early spring, apply fertilizer once more according to the above method, but do not water.
Growing Environment of Ardisia crenata
Ardisia crenata likes a warm, humid, shaded, and well-ventilated environment. Its growth temperature is 8-32°C. Its optimum growth temperature is 16-30°C. When the natural temperature is higher than 32°C, growth stagnates, and shading, ventilation, and humidification should be strengthened (relative air humidity 70%-80%) to lower the temperature. When the winter temperature is below 3°C, antifreeze measures should be taken. It is not tolerant of drought, barren soil, or exposure to blazing sun. It grows poorly under full-sun sunlight and is also not suitable for waterlogged environments. It has low requirements for soil, but grows well in loose, moist, well-drained, humus-rich acidic or slightly acidic sandy loam or loam with shade.
Ardisia crenata has abundant fruit, bright red and gorgeous, contrasting beautifully with the green leaves, extremely beautiful, and with great ornamental value. It is hoped that the above content can help you solve problems during your cultivation process.
