Why Are My Mango Leaves Turning Yellow?
Yellow leaves on Mango can be alarming, but understanding the cause helps you fix the problem quickly.
Quick Diagnosis
Most Common Cause:
Yellowing leaves in Mangifera indica may indicate nutrient deficiencies, such as nitrogen or iron, water stress, or disease, affecting overall plant health and productivity.
Common Causes of Yellow Leaves in Mango
1. Overwatering
How to identify:
- Soil is constantly wet or soggy
- Lower leaves yellow first
- Leaves may feel soft or mushy
- Possible musty smell from soil
Solution:
- Allow soil to dry out between waterings
- Check drainage holes aren't blocked
- Consider repotting with fresh, well-draining soil
- Adjust watering to every 7–14 days, depending on climate and soil moisture
2. Underwatering
How to identify:
- Soil is bone dry
- Leaves are crispy or crunchy
- Yellowing starts at tips/edges
- Plant looks wilted
Solution:
- Water thoroughly until water drains from bottom
- Establish regular watering schedule
- Consider using a moisture meter
- Mist leaves to increase humidity
3. Nutrient Deficiency
How to identify:
- Nitrogen deficiency: Lower leaves yellow first
- Iron deficiency: Young leaves yellow with green veins
- Magnesium deficiency: Yellowing between leaf veins
- Overall pale appearance
Solution:
- Apply balanced fertilizer every 2–3 months during active growth, with balanced fertilizer
- Use fertilizer appropriate for Mango
- Consider soil testing
- Add compost to improve soil quality
4. Incorrect Lighting
How to identify:

5. Natural Aging

Solution:
