Root Rot on Money Tree
Money Tree (Pachira aquatica)
Symptoms
- roots that are dark, mushy, and falling apart when unpotted
- a sour, swampy smell rising from the pot when disturbed
- yellowing leaves across the plant despite this species' moisture tolerance
- soft spots at the base of the trunk
- pot still heavy and the mix noticeably damp well over a week after the last watering
Causes
Prolonged waterlogging beyond what even this wetland-adapted species tolerates
By the time rot is confirmed, the plant's genuine wetland tolerance has usually already been stretched well past what it can actually absorb in a container — the swamp environment this species comes from cycles floodwater through and refreshes it, while a pot just holds the same stagnant water in place against the roots for as long as the owner keeps adding more.
Poor drainage
Even a species with genuine tolerance for damp soil has a ceiling, and a container that can't drain — whether from blocked or absent holes, or a mix too dense to let water pass through — pushes past that ceiling by keeping the same water in constant contact with the roots rather than letting it move through and out.
Trapped moisture around a braided trunk section
On specimens with a braided trunk, water or debris caught in the woven gaps near the soil line can keep that section of trunk consistently damp, occasionally contributing to rot starting at the base rather than purely from waterlogged soil.
How to Fix It
- 1
Before going straight to the roots, check the braid junction itself for softness or discoloration — rot on this plant frequently starts where the woven stems press against each other, not at the soil line, and that spot is easy to skip if you assume the roots are the whole story.
- 2
Free the rootball from the pot and work through each of the braided stems individually rather than treating the root mass as one unit, since it's common for rot to reach one stem's roots significantly worse than another's — anything pale and resistant to gentle pressure stays, anything dark and yielding comes off.
- 3
Trim rotted roots and any soft stem-base tissue back to firm material with a clean, sharp blade, treating each braided stem individually since one stem can be affected while its neighbors remain healthy.
- 4
Repot into fresh, well-draining mix, sizing the pot to the remaining root mass rather than the original container if a significant portion of roots had to be removed.
- 5
Water conservatively for the following few weeks, checking the braid junction periodically for renewed trapped moisture as you gradually resume a normal watering rhythm.
Prevention
- Check the braided trunk junction periodically for trapped moisture or debris, not just the general soil moisture
- Allow the top one to two inches of soil to dry before watering, despite this species' relative moisture tolerance
- Pot the braided trunk in a mix that drains fast and a container with real drainage holes, since the braid traps water at its base longer than a single-stem plant would
