Why does your Anthurium andraeanum Bambino Red have yellow leaves? Diagnose the cause and fix it with our step-by-step guide.
Anthuriums are highly susceptible to fungal pathogens like Phytophthora when soil remains saturated. Excessive moisture suffocates the roots, leading to a lack of oxygen and subsequent leaf yellowing.
A lack of nitrogen prevents the plant from producing chlorophyll, which manifests as a general yellowing starting with older leaves. This is common in compact cultivars if the potting medium has become depleted.
While Anthurium andraeanum requires bright light, direct afternoon sun can cause chlorophyll breakdown and yellowing/bleaching of the leaves. The 'Bambino' variety is particularly sensitive to heat scorch.
Anthuriums are tropical plants that thrive in consistent warmth. Exposure to drafts or temperatures below 60°F (15°C) can cause metabolic shock and chlorosis.
