Root-Rot on fiddle leaf fig
What's Happening
Root rot in Fiddle Leaf Fig develops from prolonged soil moisture retention in anaerobic conditions, primarily caused by overwatering or poorly draining potting mix. Ficus lyrata's epiphytic root systems require high aeration and cannot tolerate waterlogged substrates. Low light conditions (<1000 lux) compound the issue by slowing transpiration and prolonging soil moisture retention, creating ideal conditions for Pythium and Phytophthora pathogens.
How to Fix It
- 1
Gently remove plant from pot and inspect roots; healthy roots are firm and white
- 2
Trim all mushy, blackened roots with sterilized shears
- 3
Rinse remaining healthy roots with hydrogen peroxide solution (1:4 dilution)
- 4
Repot in fresh, well-draining soil mix with added perlite and orchid bark
- 5
Water sparingly post-repot; monitor for new growth over 4-6 weeks
What You'll Need
How to Prevent It
Use well-draining soil mix (50% potting soil, 30% perlite, 20% orchid bark). Water only when top 2-3 inches are dry. Ensure bright indirect light (2000-5000 lux) to maintain healthy transpiration rates. Use pots with drainage holes and elevate for airflow.
