Seeing your ZZ plant’s lush green leaves turn brown can be upsetting, especially after all the care you’ve given it.
Don’t worry! Most browning issues can be fixed.
In this guide, I’ll explain the common causes, how to fix them, and prevent future problems. Let’s get your ZZ plant looking its best again!
Common Causes of Brown ZZ Plant Leaves
ZZ plant leaves usually turn brown due to overwatering, underwatering, too much direct sunlight, or temperature stress. Let’s dive into each cause.
Overwatering Issues
Overwatering is the top reason for brown leaves. Too much water starves the roots of oxygen, leading to root rot.
Signs of Overwatering:
- Soggy soil for days
- Drooping or mushy leaves
- Foul smell from the soil
Solution:
- Ensure your pot has proper drainage.
- Check soil moisture with your finger or a moisture meter.
- Allow the soil to dry before watering again.
Underwatering Problems
Underwatering dries out leaves, turning them brown.
Signs of Underwatering:
- Dry, crumbly soil
- Crispy, brittle leaves
Solution:
- Water when the top 2 inches of soil are dry.
- Water evenly but avoid standing water.
Sunlight and Temperature Stress
ZZ plants love bright, indirect light. Too much direct sunlight scorches leaves; too little light weakens them.
Signs of Sunlight Stress:
- Brown patches
- Curling or drying leaves
Solution:
- Keep in bright, indirect light.
- Avoid long periods of direct sunlight.
Temperature Tips:
- ZZ plants prefer 65–75°F (18–24°C).
- Keep away from drafts, heaters, or AC vents.
