Why does your Anthurium andraeanum Orange Champion have yellow leaves? Diagnose the cause and fix it with our step-by-step guide.
Anthuriums are highly susceptible to root suffocation; excessive moisture in the substrate prevents oxygen from reaching the roots, leading to fungal decay. This disrupts nutrient transport, causing older leaves to turn yellow.
A lack of nitrogen often manifests as uniform yellowing across older leaves, while magnesium deficiency can cause interveinal chlorosis. In high-quality cultivars like 'Orange Champion', rapid growth can deplete available soil nutrients quickly.
Anthuriums require high humidity (above 60%) to thrive; low humidity causes physiological stress that can lead to chlorosis and leaf tip necrosis. This stress interferes with the plant's ability to regulate transpiration.
Excessive buildup of mineral salts from tap water or over-fertilization can burn the delicate root hairs of Anthuriums. This toxicity prevents efficient water uptake, resulting in yellowing foliage.
