What to Do When Pachira Leaves Turn Yellow? Cause Analysis and Solutions
1. Reasonable Watering
Cause: Pachira is a potted plant. If too much water is given or watering is too frequent, the leaves will turn yellow. Waterlogged potting soil can lead to oxygen deficiency, and once oxygen is lacking, its roots will rot, making it difficult for them to breathe, and the leaves will turn yellow.
Solution: Control the amount of water well. It is best to wait until the yellow leaves recover before watering again. If you cannot control the amount of water well, you can use misting instead. Although the amount of water should be reduced, do not go without watering for a long time either; water reasonably.
2. Appropriate Light Exposure
Cause: Pachira likes sunlight, but it cannot be exposed to sunlight for a long time. Direct strong light will cause the leaves to turn yellow. If it is placed in a dark place without light for a long time, it cannot carry out photosynthesis normally, which will also cause the leaves to turn yellow.
Solution: In spring and autumn, give it an appropriate amount of sunlight exposure, but in summer when the sunlight is strong, take shading measures or move it to a place with diffused light. In winter, it can be exposed to direct sunlight.
3. Scientific Fertilization
Cause: If too much fertilizer is usually applied or if undecomposed fertilizer is applied, it will burn its roots, causing the leaves to turn yellow and fall off.
Solution: During the growth period of Pachira, fertilize scientifically. You can apply a light fertilizer once every 20 days. In addition, when repotting, you can apply some fully decomposed base fertilizer. Only with scientific fertilization can it grow more luxuriantly.
4. Adjusting the Temperature
Cause: If the temperature is low in winter, cold damage will occur, causing the leaves to turn yellow or fall off, and in severe cases, it will cause the plant to die.
Solution: Give it a growing environment of 20-30°C. The minimum temperature should not be lower than 5°C. If the temperature is low, you can cover it with plastic film or a plastic bag, which can provide a certain effect of protecting against cold and keeping it warm.
