Understanding Root Rot: The Basics

Root rot is essentially a disease that attacks a plant's root system, causing the roots to decay and eventually die. It's particularly common in indoor plants where drainage and watering habits might not be optimal.

What Causes Root Rot?

Several factors contribute to root rot development:

  • Overwatering: The primary culprit in most cases
  • Poor drainage: Both in soil and pots
  • Compacted soil: Preventing proper air circulation
  • Inappropriate pot size: Usually too large for the plant
  • Fungal pathogens: Thriving in consistently wet conditions

Early Warning Signs

Catching root rot early is crucial. Look out for these symptoms:

  • Yellowing leaves, particularly lower ones
  • Wilting despite moist soil
  • Slow or stunted growth
  • Leaf drop
  • Musty smell from the soil
  • Soft, mushy stems near the soil line

Detailed Diagnosis Process

To confirm root rot, follow these steps:

  1. Carefully remove the plant from its pot
  2. Examine the roots closely:
    • Healthy roots: White or light-coloured, firm
    • Rotted roots: Brown/black, mushy, often with an unpleasant odour
  3. Check the soil moisture and texture

Treatment Guide

If you've confirmed root rot, act quickly with these steps:

  1. Remove the plant from its pot
  2. Wash away old soil completely
  3. Trim away affected roots with sterilised tools
  4. Apply a fungicide if necessary
  5. Repot in fresh, well-draining potting medium
  6. Reduce foliage to match reduced root system

Prevention Strategies

Preventing root rot is always better than treating it. Here's how:

  • Use well-draining soil mixes
  • Choose pots with drainage holes
  • Water only when top 2-3 inches of soil is dry
  • Ensure good air circulation
  • Use appropriate pot sizes

Plant-Specific Considerations

Moisture-Loving Plants

Calatheas and ferns need consistent moisture but still require proper drainage.

Drought-Tolerant Plants

Cacti and succulents are particularly susceptible to root rot due to overwatering.

Large Plants

Monsteras and palms need special attention due to their size and root volume.

Recovery Tips

After treating root rot:

  • Place plant in bright, indirect light
  • Maintain optimal temperature (18-24°C)
  • Hold off on fertilising until new growth appears
  • Monitor humidity levels
  • Be patient - recovery takes time

When to Consider Replacement

Sometimes, despite our best efforts, a plant may be too far gone. Consider getting a new plant if:

  • More than 50% of roots are affected
  • The main stem is completely rotted
  • No healthy roots remain
  • The plant shows no signs of recovery after treatment

Expert Tips for Success

Professional plant care tips to remember:

  • Different plants have different watering needs
  • Seasonal adjustments are necessary
  • Regular monitoring prevents problems
  • Quality potting medium is crucial
