yellow leaves overwatering root rot and Pothos
Quick answer
If yellow leaves overwatering root rot is what's going on with your Pothos, the most likely cause is: Overwatering in pothos is about frequency, not volume. When soil stays moist for 7+ days, anaerobic bacterial communities (dominated by Proteobacteria and Actinobacteriota) colonize roots, causing oxygen deprivation. The plant's fibrous adventitious roots—which cluster at pot bottom and perimeter—remain waterlogged while surface soil appears dry, creating a hidden root rot condition.
Start here:
- 1. 1. Check deep moisture: Insert wooden skewer to pot bottom—moisture at depth = delay watering
- 2. 2. Unpot gently: Inspect roots for black/mushy sections and sour odor

4. H2O2 treatment: Soak remaining roots in 3% hydrogen peroxide solution (1:1 with water) for 20 minutes

5. Repot in dry, chunky mix; water only after 1 week recovery

6. Resume watering when soil is dry to 2-3 inches depth
Keep yellow leaves overwatering root rot from repeating on this Pothos
Water only when top 2-3 inches of soil are completely dry; use finger test or moisture meter at 80% pot depth; ensure pots have drainage holes; use chunky aroid mix (50% potting soil, 30% perlite, 20% bark); bottom-water only when necessary.
