Root Rot Signs and What to Do
Root rot is most likely when yellowing, drooping, wet soil, sour smell, and mushy roots show up together.
Read the guidePlant + symptom guide
Root rot is more likely when decline comes with wet soil, sour smell, mushy roots, soft stems, or a sealed pot. It is worth checking carefully before repotting.
For snake plant, adjust the diagnosis around this plant profile: Snake plants store water and decline quickly in wet, cold, or no-drainage setups. Soft yellow leaves are more concerning than a single dry tip.
Smell the soil and look for sour or swampy odor.
Slide the root ball out only if decline is severe or the pot has no drainage.
Check for brown, mushy roots versus firm pale roots.
Feel for soft, translucent, or collapsing leaf bases.
Check whether the plant is in a sealed pot or dense moisture-retentive mix.
Isolate the plant if rot is severe or pests are also present.
Trim dead roots and repot into a faster-draining mix if roots are mushy.
Do not fertilize while roots are recovering.
