Why does your Anthurium andraeanum Aristo have yellow leaves? Diagnose the cause and fix it with our step-by-step guide.
Anthuriums are highly susceptible to waterlogging. Excess moisture in the substrate leads to anaerobic conditions, causing root decay which prevents the plant from transporting nutrients, resulting in chlorosis (yellowing).
As a heavy feeder, an Aristo may develop yellowing leaves if nitrogen or magnesium levels in the potting medium are depleted. Nitrogen deficiency typically presents as uniform yellowing of older leaves first.
Anthuriums require bright, indirect light to maintain chlorophyll production. If the plant is in too much shade, it cannot photosynthesize efficiently, leading to pale or yellowing foliage.
Aristo varieties are tropical and sensitive to cold fluctuations. Exposure to cold drafts from air conditioning or windows can shock the plant, causing sudden leaf yellowing and wilting.
