Dealing with Yellow Leaves on Azaleas: Causes and Solutions

Dealing with Yellow Leaves on Azaleas: Causes and Solutions Yellowing leaves on azaleas can indicate stress from improper watering, nutrient deficiencies, or environmental issues. Identifying the cause early helps restore plant health and maintain vibrant foliage. Common Causes & Fixes Overwatering or Poor Drainage Cause: Waterlogged roots lead to oxygen deprivation. Fix: Ensure well-draining soil and water only when the top inch of soil feels dry. Underwatering Cause: Dry soil stresses the plant. Fix: Water deeply when the soil is dry but avoid soggy conditions. Iron Chlorosis (Nutrient Deficiency) Cause: Azaleas prefer acidic soil (pH 4.5-6.0); alkaline soil blocks iron absorption. Fix: Test soil pH and amend with sulfur or iron chelates if needed. Nitrogen Deficiency Cause: Lack of nitrogen leads to pale yellow older leaves.
