Pothos: pest vulnerability
Quick answer
Soil-borne fungal pathogens Rhizoctonia solani and Sclerotium rolfsii attack pothos roots through cell wall degrading enzymes (pectate lyase and cellobiose dehydrogenase). These pathogens persist as vegetative mycelium and/or sclerotia, causing necrotrophy that drastically reduces root length, fresh weight, and dry weight.
Start here:
- 1. Apply thyme oil nanoemulsion at 3000 ppm concentration to infected soil and roots
- 2. For severe infections, use clove oil nanoemulsion at 3000 ppm as alternative treatment

How to handle pest vulnerability on Pothos
- 1
Apply thyme oil nanoemulsion at 3000 ppm concentration to infected soil and roots
- 2
For severe infections, use clove oil nanoemulsion at 3000 ppm as alternative treatment
- 3
Remove plant from pot, trim black/mushy roots with sterilized shears, rinse remaining roots
- 4
Repot in fresh well-draining aroid mix (50% potting soil, 30% perlite, 20% orchid bark) with drainage holes
- 5
Allow soil to dry between waterings; water only when top 2-3 inches are dry
Ongoing Pothos notes
Use well-draining soil mix with perlite and orchid bark; avoid oversized pots that retain excess moisture; quarantine new plants 2-4 weeks before introducing to collection; maintain 40-60% humidity with good airflow
