What is the reason why the leaves of white anthurium turn yellow?

Anthurium belongs to the genus Spathiphyllum of the Araceae family. It is a common indoor foliage plant. It is evergreen all year round, has large leaves and beautiful plant shape, making it very suitable for indoor planting. However, when planting and maintaining Anthurium, many people often encounter the problem of yellowing leaves of Anthurium. So what is the cause? Let’s learn more about it below.

1. Soil becomes alkaline

Anthurium prefers acidic soil. If planted in the north, due to the alkaline water and soil quality, long-term application will cause the leaves to gradually fade, turn yellow, and even fall off.

2. Inappropriate light exposure

White calla lilies need a moderate amount of light, but cannot tolerate direct sunlight. If white calla lilies are exposed to strong sunlight for a long time, the leaves will be sunburned and yellow spots will appear. Therefore, the white calla lily should be moved to a semi-shaded environment in time to avoid direct sunlight.

3. Insufficient watering

When there is insufficient watering, the leaves of the plant will turn yellow due to lack of water. At this time, the white calla lily should be watered in time. During the growing season, water frequently and be careful to keep the substrate moist. It should be noted that the amount of water should not be too large, so as to avoid water accumulation and submergence of the roots, affecting the breathing of the white calla lily.

4. Temperature is too low

The suitable temperature for the growth of anthurium is around 20℃. If the temperature is below 5℃ in winter, the plant will easily freeze. Long-term low temperature will also cause yellow leaves of anthurium. It is recommended to move the plants indoors in time to keep them warm and ensure that the indoor temperature is not lower than 10°C to protect the plants from wintering smoothly and reduce the phenomenon of yellow leaves.

5. Improper fertilization

Too much fertilizer will cause salt accumulation and burn the plant roots, while too little fertilizer will lead to nutrient deficiency, both of which will cause the problem of yellow leaves on white calla lilies. Therefore, it is necessary to apply fertilizer reasonably. Generally, nutrient solution is very suitable for hydroponic white anthurium, while nitrogen, phosphorus and potassium compound fertilizer should be used as much as possible for soil-grown white anthurium.

6. Impact of pests and diseases

Anthuriums may be attacked by pests and diseases, such as leaf spot and aphids, which can cause the leaves to turn yellow, wilt, or even die.

In general, the phenomenon of yellowing leaves of white calla lilies is quite common, but it is not scary as long as you find out the reason. By focusing on taking appropriate measures according to the specific situation, the adverse effects brought by the yellow leaves of white calla lily can be effectively resolved.
