Nutrient Deficiency (Nitrogen or Magnesium)

Improper Light Intensity

Too much direct sunlight can scorch the thick leaves, causing them to fade to yellow, while too little light prevents the plant from maintaining metabolic processes. Anthuriums require bright, indirect light specifically.

Temperature Fluctuations and Cold Stress

Anthurium andraeanum is a tropical plant that thrives in stable temperatures; exposure to drafts or temperatures below 60°F (15°C) can trigger a stress response resulting in leaf yellowing.

1 Move your Anthurium to a stable, warm environment away from cold drafts, windows, or air conditioning vents to maintain temperatures consistently above 60°F.

2 Monitor soil moisture closely during temperature shifts, as cold stress can slow evaporation; use a moisture meter to ensure the soil is not staying too wet.
