Rhizome Rot in ZZ Plant
Commonly affects: Zamioculcas zamiifolia (ZZ Plant)
Stems become soft and mushy at the base, sometimes detaching easily from the rhizome, and the underground rhizome itself appears brown, soft, and foul-smelling when checked.
Potential Causes
- 1Overwatering, since the rhizome is specifically adapted to store water and rots quickly in constantly wet soil
- 2Poorly-draining soil or a pot without adequate drainage
- 3Watering too frequently for a plant that tolerates significant drought
Solution Steps
- 1Remove the plant from its pot and cut away all soft, rotten rhizome tissue with a sterilised blade
- 2Repot into fresh, well-draining potting mix
- 3Water far less often going forward, letting soil dry out completely between waterings
- 4Save any healthy rhizome sections and stems for propagation if the original plant is severely affected
Prevention Tip
The ZZ Plant's rhizome is essentially a built-in drought reserve â treat this plant more like a succulent than a typical tropical houseplant when it comes to watering.
