Why Are My Spider Plant Leaves Turning Yellow?
Yellow leaves on Spider Plant can be alarming, but understanding the cause helps you fix the problem quickly.
Quick Diagnosis
Most Common Cause:
Yellow leaves in Chlorophytum comosum are often indicative of overwatering, nutrient deficiencies, or pest infestations, which can disrupt chlorophyll production and photosynthesis.
Common Causes of Yellow Leaves in Spider Plant
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 7–10 days, allowing soil to dry slightly between waterings
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 4–6 weeks during spring and summer, none in fall and winter
- Use fertilizer appropriate for Spider Plant
- Consider soil testing
- Add compost to improve soil quality
4. Incorrect Lighting
How to identify:
- Too much light: Bleached, pale yellow leaves
- Too little light: Pale yellow with leggy growth
- Uneven yellowing pattern
Solution:
- Spider Plant needs bright indirect light, tolerates partial shade light
- Move to appropriate light location
- Bright indirect light for 6–8 hours daily; tolerates lower light but grows slower.
5. Natural Aging
How to identify:
- Only bottom/oldest leaves yellowing
- New growth looks healthy
- Gradual process
- No other symptoms
Solution:
- This is normal - no action needed
- Remove yellow leaves for aesthetics
- Continue normal care routine
Prevention Tips for Spider Plant
- Proper Watering: Water every 7–10 days, allowing soil to dry slightly between waterings
