Rosemary Leaves Turning Yellow: Causes and How to Fix It
Rosemary Leaves Turning Yellow
If your rosemary leaves are turning yellow, the plant is likely experiencing stress caused by environmental conditions or improper care. Rosemary (Rosmarinus officinalis) is a hardy herb, but incorrect watering, poor soil drainage, or lack of sunlight can lead to yellow foliage.
Identifying the underlying cause is the key to restoring plant health.
Overwatering
Overwatering is the most common reason rosemary leaves turn yellow.
- Soil remains constantly wet
- Roots receive too little oxygen
- Root rot may develop
Allow the soil to dry before watering again. Learn proper watering methods in Rosemary Watering Guide.
Poor Soil Drainage
Rosemary requires well-draining soil. Heavy soil that retains moisture can cause yellow leaves.
- Use sandy soil
- Add perlite or pumice
- Avoid dense clay soil

Lack of Sunlight
Rosemary needs plenty of sunlight to maintain healthy green foliage.
- At least 6–8 hours of sunlight
- Place near a sunny window if grown indoors
Nutrient Deficiency
Although rosemary requires little fertilizer, nutrient deficiencies may cause leaf discoloration.
- Slow growth
- Pale or yellow leaves
Natural Aging
Sometimes older leaves naturally turn yellow and fall off as the plant grows.
- Lower leaves may yellow first
- This is normal if new growth appears healthy
