Pothos Root Rot — Multiple Vines Yellowing at Once Is the Warning
Golden Pothos (Epipremnum aureum)
Symptoms
- yellow leaves appearing on multiple vines at the same time
- soil that stays wet 2+ weeks after watering
- a sour or musty smell from the pot
- the plant not recovering after a period of reduced watering
- roots appearing brown, soft, and malodorous when the plant is unpotted
Causes
Pythium or Rhizoctonia in consistently moist soil
Pothos roots are relatively fine and fibrous compared to the fleshy roots of some other aroids. This means they can be damaged by root rot pathogens relatively quickly once waterlogged conditions are established. Pythium ultimum is the most common pathogen. The fibrous root system of a trailing Pothos in a hanging basket or shelf pot can deteriorate significantly before above-ground symptoms appear — each vine has access to multiple roots, and a vine does not yellow until the specific roots serving it are substantially compromised.
How to Fix It
- 1
Unpot the plant and rinse the tangle of fine roots clean, then work through them vine by vine rather than judging the root mass as a whole — because each trailing vine draws on its own cluster of roots, one vine's roots can be visibly white and firm while a neighboring vine's have already gone dark and mushy.
- 2
Cut all rotted roots to healthy tissue. For Pothos with many thin roots, this may mean removing a significant volume of root material. Healthy tissue is the reference — do not leave any discolored root in place.
- 3
Trim above-ground vines proportionally: if you removed 40% of the root mass, trim 40% of the above-ground vine length. This brings the plant's water demand in balance with its remaining root capacity.
- 4
Repot in fresh, well-draining mix. Water once lightly to settle, then hold off until the trimmed-back root mass has had a real chance to dry out before watering again.
- 5
Save any healthy vine sections as cuttings: place in water, root, and pot to replace the declining plant if the root rot was severe.
Prevention
- Judge the next watering by how the mix actually feels at the base of the pot, not by a fixed number of days, since a trailing plant's several vines can mask early wilting until root loss is already significant
- Ensure drainage holes are present and functional
- For hanging baskets: check more frequently in summer when evaporation is higher but do not overcompensate
