root rot from overwatering and Pothos
Quick answer
If root rot from overwatering is what's going on with your Pothos, the most likely cause is: Water fills soil pores, displacing oxygen (O₂) needed for root respiration. Without O₂, root cells cannot metabolize, leading to anaerobic conditions that favor Pythium and Phytophthora spp. Overwatering is the most common cause of houseplant failure.
Start here:
- 1. Insert finger 1 inch into compost — if damp, do not water
- 2. For clay pots: tap pot with cotton reel on cane — dull thud = moist, clear ring = dry

How to correct root rot from overwatering on Pothos
- 1
Insert finger 1 inch into compost — if damp, do not water
- 2
For clay pots: tap pot with cotton reel on cane — dull thud = moist, clear ring = dry
- 3
For dried root-balls: stand pot in bucket of water until bubbles stop
- 4
After watering: always empty saucer/cached-pot of standing water
Keep root rot from overwatering from repeating on this Pothos
Use pot with drainage hole. Allow top 1-2 inches of peat-based compost to dry before re-watering; loam-based compost can be slightly more moist. Never leave pots standing in saucered water. Plants in clay pots need watering more often than those in plastic pots.
