Why does your Anthurium andraeanum Eternity have sudden leaf drop? Diagnose the cause and fix it with our step-by-step guide.
Anthuriums are highly susceptible to root suffocation; excessive moisture in the substrate leads to Phytophthora or Pythium, causing the plant to shed leaves as the root system fails to support foliage.
This cultivar is tropical and sensitive to sudden temperature drops; exposure to air conditioning vents or cold window drafts can trigger an immediate stress response resulting in leaf abscission.
Anthuriums require high ambient humidity; when the air becomes too dry, especially during winter heating seasons, the plant may drop older leaves to conserve moisture for the remaining foliage.
Fungal pathogens like Colletotrichum can colonize leaf tissue, often preceded by small spots, which eventually leads to the entire petiole detaching from the stem as the plant attempts to isolate the infection.
