To fix this issue, make sure that you water your plant regularly and that the soil is moist but not waterlogged. You can check the moisture level of the soil by sticking your finger in it; if it feels dry, it's time to water your plant.

Nutrient Deficiency

Anthurium requires specific nutrients to grow healthy foliage and flowers. If your plant is not getting enough nutrients, its leaves may turn yellow.

To address this issue, you can fertilize your plant with a balanced fertilizer that contains nitrogen, phosphorus, and potassium. You can also add organic matter to the soil, such as compost or worm castings, to increase the nutrient content.

Pest Infestation

To get rid of these pests, you can use insecticidal soap or neem oil. You should also isolate the infected plant to prevent the pests from spreading to other plants.

Environmental Stress

Anthurium is a tropical plant that thrives in warm and humid conditions. If your plant is exposed to extreme temperatures or dry air, its leaves may turn yellow.

To solve this issue, you can place your plant in a shaded area where it can get indirect sunlight. You can also mist the leaves regularly to increase the humidity around the plant.

In conclusion, yellowing of Anthurium leaves can be caused by various factors such as overwatering, underwatering, nutrient deficiency, pest infestation, and environmental stress. By identifying the underlying cause, you can take appropriate steps to fix the issue and ensure the health of your plant.
