Why does your Anthurium andraeanum Maine have yellow leaves? Diagnose the cause and fix it with our step-by-step guide.
Anthuriums are highly susceptible to stagnant moisture; excessive water in the medium leads to anaerobic conditions that cause roots to decay, preventing oxygen uptake and resulting in chlorosis (yellowing) of older leaves.
A lack of available nitrogen can cause older leaves to turn uniformly yellow, while magnesium deficiency often presents as interveinal chlorosis on the larger foliage of the Maine cultivar.
Too much direct sunlight can scorch the delicate tissues of the Anthurium, while too little light prevents photosynthesis, leading to a pale, yellowing appearance in the foliage.
Anthuriums are tropical plants that thrive in consistent warmth; sudden drops in temperature or exposure to drafts can cause metabolic disruption and leaf yellowing.
