Temperature Fluctuations and Cold Stress

Anthuriums are tropical plants that require consistent warmth; sudden drops in temperature or exposure to drafts can trigger a stress response resulting in yellowing foliage.

Rare

1 Relocate your Anthurium to a stable, warm environment away from cold drafts, air conditioning vents, or windows during winter.

2 Monitor soil moisture closely to ensure the plant is not being overwatered while in a stressed state, as cold temperatures slow down evaporation.
