Causes of Brown Leaves on Anthurium Plants & How to Fix It

Excess Direct  Sunlight

Typically, anthuriums thrive best in the shade. The flamingo plant grows optimally under 60% sunlight or 1,800 to 2,500-foot candles. Excess direct sunlight is a major cause of brown leaves, leading to wilting and death of plants if left untreated.


Gardeners are likely to overwater their houseplants if they don’t strictly follow the watering schedule. Besides water being a primary cause of this issue, planting in poorly aerated soil, growing plants in large pots, and using a pot with few drainage holes play huge roles.
