Introduction to Root Rot
Root rot is one of the most serious problems facing houseplants in American homes. Caused by overwatering and poor drainage, root rot can kill plants quickly if not treated promptly.
What Causes Root Rot?
- Overwatering: The #1 cause of root rot
- Poor Drainage: Pots without drainage holes
- Dense Soil: Heavy soil that retains too much water
- Fungal Pathogens: Thrive in wet conditions
Signs of Root Rot
- Yellow Leaves: Often the first visible sign
- Wilting: Despite wet soil
- Mushy Stems: Soft, brown stems near soil
- Foul Smell: Musty or rotten odor from soil
- Black Roots: Visible when repotting
Step-by-Step Treatment
- Remove Plant: Carefully take plant out of pot
- Inspect Roots: Healthy roots are white/cream colored
- Trim Rotten Roots: Cut away black, mushy roots
- Clean Remaining Roots: Rinse with clean water
- Treat with Fungicide: Optional but recommended
- Repot in Fresh Soil: Use well-draining mix
- Water Sparingly: Wait before first watering
Prevention Tips
- Use pots with drainage holes
- Use well-draining soil mix
- Water only when soil is dry
- Empty drainage trays after watering
- Reduce watering in winter
When to Give Up
If more than 50% of roots are rotten or the main stem is mushy, the plant may be beyond saving. Consider propagating healthy parts if possible.
Conclusion
Root rot is serious but treatable if caught early. Prevention through proper watering is always better than cure.
