Why does your Anthurium andraeanum Mont Blanc have sudden leaf drop? Diagnose the cause and fix it with our step-by-step guide.
Excessive substrate moisture or poor drainage leads to anaerobic conditions, causing the roots of your Anthurium to decay. As the root system fails, it can no longer support foliage, triggering a stress response known as leaf abscission.
Anthurium andraeanum is highly sensitive to sudden drops in temperature, especially below 60°F (15°C). Rapid exposure to cold drafts can cause the plant to shed leaves as a survival mechanism.
White Anthuriums thrive in humidity levels above 60%. When the surrounding air is too dry, the plant loses moisture through transpiration faster than the roots can replace it, leading to wilting and eventual leaf drop.
A lack of essential macronutrients prevents the production of chlorophyll and structural cell components. Chronic deficiency weakens the petiole connection, making leaves prone to falling off.
