This article guide: Tips from the Flower Clinic on Epipremnum aureum, reasons and solutions for the yellowing of Epipremnum aureum leaves, the editor will provide you with detailed answers next.
Many flower enthusiasts have noticed the yellowing of Epipremnum aureum leaves during indoor cultivation. So, why do Epipremnum aureum leaves turn yellow, and what should be done if the leaves turn yellow?
I. Main Reasons for the Yellowing of Epipremnum aureum Leaves
Generally speaking, the yellowing of Epipremnum aureum leaves is often caused by bacteria in the water for hydroponic cultivation, while for soil cultivation, it might be due to root rot. Compared to soil cultivation, hydroponic Epipremnum aureum is more likely to have yellow leaves. The specific factors causing the yellowing of Epipremnum aureum leaves mainly include improper watering, unbalanced lighting, and incorrect fertilization. The following editor will provide a detailed analysis of the three major factors causing yellowing in Epipremnum aureum leaves.
1. Improper watering: Too much or too little watering can cause Epipremnum aureum leaves to turn yellow. If the leaves appear dark yellow without luster and the new shoots shrink and do not grow, it may be due to excessive watering. If the leaf tips or edges become dry and withered, and the new leaves grow normally while the old leaves turn yellow and fall off, it may be due to insufficient watering.
2. Sunlight: Epipremnum aureum prefers shade. Strong sunlight can cause the tips and edges of the leaves to wither, and the sun-exposed part of the leaves may develop yellow spots. Conversely, if kept in a dark environment for a long time, the leaves will not receive enough sunlight to produce chlorophyll, which can also cause the leaves to turn yellow. Supplemental lighting is needed.
3. Fertilizer yellowing: Over-fertilization, high concentration of fertilizer, or even lack of fertilizer can cause the leaves to turn yellow. When over-fertilized, the leaves become thick without luster and the leaf surface looks unexpanded, with old leaves turning yellow and falling off. This can be mitigated by rinsing to reduce the fertilizer. When lacking fertilizer, the leaf color will become lighter, appearing pale green or yellow, and fertilization should be supplemented promptly. In severe cases, the potting soil should be changed.
II. Solutions for the Yellowing of Epipremnum aureum Leaves
The solutions for the yellowing of Epipremnum aureum leaves should be adjusted according to the cause of the yellowing. Since Epipremnum aureum can be propagated by cuttings, each node has a leaf bud, and planting just one node can result in growth. Therefore, when the leaves of the cultivated Epipremnum aureum turn severely yellow, the rotten roots should be removed, the yellow leaves should be removed, and the plant should be replanted. When using hydroponics, the water should be changed to new water. It is also possible to cut the branches that have not yet turned yellow and replant them. During the planting process, two to three nodes should be buried, and the same applies to hydroponics. The water should be changed every three to four days (preferably with cold boiled water). The newly planted cuttings should not be exposed to strong sunlight and can be placed in a location with weak light. After about 20 days, the newly planted Epipremnum aureum will root and grow.
