Root rot is a common plant ailment caused by overwatering and poor drainage, leading to the decay of roots. Identifying root rot early is crucial for saving affected plants. This guide will help you understand the causes, symptoms, and preventive measures for root rot.
What Causes Root Rot?
Root rot primarily occurs due to overwatering and inadequate drainage. When roots sit in waterlogged soil, they can’t access oxygen, leading to decay. Here are the main causes:
- Overwatering: Excessive watering prevents roots from breathing, leading to suffocation and decay.
- Poor Drainage: Soil that doesn’t drain well retains water, creating an environment for root rot.
- Fungal Infections: Fungi such as Phytophthora thrive in wet conditions, attacking and decomposing roots.
- Compacted Soil: Dense soil limits water flow and air circulation, exacerbating root rot conditions.
How to Identify Root Rot?
Identifying root rot early can save your plants. Look for these symptoms:
- Yellowing Leaves: Affected plants often show yellow or wilting leaves due to nutrient deficiencies.
- Soft, Mushy Roots: Healthy roots are firm and white, while rotting roots are brown and mushy.
- Stunted Growth: Plants with root rot may stop growing or grow very slowly.
- Foul Odor: Decaying roots emit a musty or rotten smell.
How to Treat Root Rot?
Treating root rot involves several steps to restore your plant’s health:
- Remove the Plant: Gently take the plant out of its pot to inspect the roots.
- Trim Affected Roots: Use sterilized scissors to cut away mushy, brown roots.
- Repot with Dry Soil: Choose a pot with drainage holes and use fresh, well-draining soil.
- Water Sparingly: Allow the soil to dry between waterings to prevent future rot.
- Apply Fungicide: Consider using a fungicide to eliminate any remaining fungal spores.
How to Prevent Root Rot?
Preventing root rot is easier than treating it. Follow these tips:
- Water Wisely: Water plants only when the top inch of soil is dry.
- Ensure Proper Drainage: Use pots with drainage holes and well-draining soil mixtures.
- Aerate Soil: Loosen soil regularly to improve air circulation and drainage.
- Monitor Plant Health: Regularly check for signs of overwatering or poor growth.

Does cinnamon help with root rot?
Cinnamon has antifungal properties and can help prevent root rot. Sprinkle cinnamon powder on the soil surface or directly on cut roots when repotting to reduce fungal growth.
Is root rot contagious?
Root rot itself is not contagious, but the conditions that cause it, such as excess moisture, can spread to nearby plants. Ensure proper drainage and avoid overwatering to prevent spreading.
