Understanding Meyer Lemon Tree Root Rot
Root rot is a condition caused by overwatering or poorly draining soil that leads to the decay of the roots. Fungi such as Phytophthora and Pythium are often responsible for this disease. When roots rot, the tree cannot absorb water and nutrients effectively, leading to decline and potential death if untreated.

Recognizing root rot early can save your Meyer lemon tree. Common signs include:
- Wilting or yellowing leaves despite adequate watering
- Stunted growth
- Soft, brown, or black roots upon inspection

Prevention Strategies
Preventing root rot involves proper watering practices and soil management. Consider the following tips:
- Ensure well-draining soil, such as sandy loam or amended garden soil
- Avoid overwatering; let the top inch of soil dry out between waterings
- Use raised beds or containers with drainage holes
- Maintain proper spacing to allow air circulation around roots
- Regularly inspect roots for early signs of decay
Recovery and Treatment
If your Meyer lemon tree shows signs of root rot, prompt action is necessary. Follow these steps:
- Gently remove the tree from its pot or ground
- Trim away all affected roots with sterilized pruning shears
- Dispose of infected soil and roots responsibly
- Repot the tree in fresh, well-draining soil
- Reduce watering frequency and avoid overwatering
- Apply a fungicide labeled for root rot if necessary
- Place the tree in a location with adequate sunlight and airflow
Long-term Care
