fungal infection on Pothos
Quick answer
If your Pothos has fungal infection, the most likely cause is: White fuzzy mold on soil surface is typically saprophytic fungi (Trichoderma, Aspergillus) feeding on organic matter in persistently moist soil. This indicates overwatering and poor drainage but does not directly harm plant roots. The mold thrives when soil remains wet for 7+ days and creates ideal conditions for fungus gnats. Unlike root rot pathogens, these surface molds are visible and easily identified by their cottony appearance.
Start here:
- 1. Remove visible mold: Gently scrape off surface mold with spoon, dispose away from plants
- 2. Apply natural antifungal: Sprinkle ground cinnamon on soil surface—it contains cinnamaldehyde which inhibits fungal growth

How to reverse fungal infection on Pothos
- 1
Remove visible mold: Gently scrape off surface mold with spoon, dispose away from plants
- 2
Apply natural antifungal: Sprinkle ground cinnamon on soil surface—it contains cinnamaldehyde which inhibits fungal growth
- 3
Flush soil: Water thoroughly with 3x pot volume to leach excess organic matter
- 4
Improve drainage: Repot using well-draining mix with 30% perlite if soil compacts easily
- 5
Allow complete drying: Wait until top 2-3 inches are bone dry before next watering
- 6
Enhance airflow: Use small fan to speed soil surface drying
Keep fungal infection off this Pothos
Water only when top 2 inches are dry. Use pots with drainage holes. Avoid excessive organic matter in soil mix. Maintain 40-60% humidity without leaf wetting. Allow soil to dry between waterings.
