Yellowing leaves on Anthurium are mostly caused by improper care

Anthurium, also known as flamingo flower and laceleaf, is an evergreen foliage and flowering plant in the Araceae family. Its leaves are leathery and glossy, and its spathes are brightly colored, making it a popular indoor potted plant. During care, yellowing leaves on Anthurium are a fairly common occurrence; in most cases it indicates a problem with the growing environment or routine management, and prompt investigation and adjustment are needed.

There are several main categories of causes for yellow leaves. Improper watering is the most common: overwatering keeps the potting soil wet for long periods and impedes root respiration, which easily causes old leaves to turn yellow and even root rot; prolonged lack of water, on the other hand, causes leaf tips and margins to dry out and yellow. As for light, Anthurium prefers diffused light; direct strong sunlight scorches the leaves and produces yellow spots, while keeping it in a too-dark corner for a long time also causes the leaves to lose their green color and yellow due to insufficient photosynthesis.

Temperature and fertilization also have an obvious effect. Anthurium is not cold-tolerant; low winter temperatures or direct cold drafts easily cause leaves to freeze, yellow and soften, and when the air is too dry the leaf tips also tend to scorch. Fertilizing too strongly or using uncomposted fertilizer burns the roots and causes large areas of leaves to yellow, while going without fertilizer for a long time and lacking nutrients makes new leaves smaller and paler in color.

After discovering yellow leaves, first check the moisture of the potting soil and the state of the roots. For plants with root rot, trim the roots and repot in fresh soil in time, then water on the principle of watering when dry and letting it dry between waterings, and place the plant in a spot with bright diffused light and good ventilation, away from air-conditioning and heating vents. During the growing season, apply light fertilizer frequently, mist the surroundings often to raise air humidity, and cut off yellow leaves that cannot recover; Anthurium can generally gradually regain its vigor.
