Look for a cluster
Wet soil alone is not proof. Root rot becomes more likely when wet soil combines with yellowing, drooping, sour smell, soft stems, or mushy roots.
Topic
Root Rot
Root rot is one of the few houseplant problems where waiting too long can remove your options. This hub focuses on wet-soil decline, sour mix, mushy roots, drooping, yellow leaves, and practical rescue steps.

Diagnosis flow
Check roots when symptoms justify it
Unpotting is stressful. Do it when the plant is worsening, the mix smells sour, or stems feel soft.
Decide rescue or propagation
If firm roots remain, rescue the root system. If most roots are gone but healthy stems remain, propagation may be the better save.
Cause patterns to compare
Chronic overwatering
Signal: The root zone stays wet for many days.
Next check: Confirm drainage, pot size, and light.
Dense or old mix
Signal: Soil compacts, smells sour, or drains slowly.
Next check: Refresh into an airy mix suited to the plant.
No-drainage container
Signal: Water cannot leave the pot or cachepot.
Next check: Move into a draining container sized to the roots.
Oversized pot
Signal: A small root ball sits inside a large wet soil mass.
Next check: Downsize if the remaining roots cannot use the volume.
What to do next
- Isolate a severely declining or sour-smelling plant.
- Trim only mushy, hollow, or slimy roots.
- Repot into fresh airy mix and a pot with drainage.
- Avoid fertilizer until new growth confirms recovery.
- Take healthy cuttings if the root system is mostly lost.
Common mistakes
- Watering wet soil to fix drooping.
- Removing firm stained roots.
- Reusing sour potting mix.
- Putting a root-pruned plant in harsh direct sun.

FAQ
Can root rot be reversed?
Rotten tissue cannot recover, but a plant can recover if enough healthy roots or propagatable stems remain and the wet condition is fixed.
What do healthy roots look like?
Healthy roots are firm and may be white, cream, tan, or light brown depending on the plant and soil. Rotten roots are mushy, hollow, slimy, or foul-smelling.
Should I isolate a plant with root rot?
Isolation is wise if there is severe decline, fungus gnats, sour soil, or pest concerns. It also gives you room to work cleanly.
