Root rot: look below the surface.
Wilting or yellowing while the soil stays wet can signal root trouble. Root rot cannot be confirmed from leaf color alone. Check drainage, the stem base and, when necessary, the roots themselves. Soft, decaying roots are more concerning than their color by itself.

What are you actually looking for?
| Check | Less concerning | Needs a closer look |
|---|---|---|
| Potting mix | Moisture changes between waterings and excess water drains. | The root ball remains saturated or stands in trapped water. |
| Roots | Firm tissue. Natural root color varies by species and growing conditions. | Soft or decaying tissue, sometimes with outer layers slipping away. |
| Stem base | Firm tissue appropriate to the plant. | A soft, darkening or collapsing base. |
| Foliage | A single older leaf changes while the plant otherwise grows. | Persistent wilting or spreading decline despite wet soil. |
First, stop adding to the problem.
Empty any standing water and check that the growing pot has drainage holes. Do not add more water or fertilizer to a saturated root ball. If the plant continues to decline, gently inspect the roots without pulling apart healthy tissue unnecessarily.
Maryland Extension describes root and crown rots and the conditions that favor them. Damage to the roots can explain why a plant wilts even though its soil is wet.
Can a plant with damaged roots be saved?
Sometimes, if enough healthy tissue remains. The next step depends on the species and extent of damage. A plant with extensive decay or a collapsing crown may not recover. A nursery or extension service can help decide whether removing damaged tissue and repotting is appropriate, or whether the plant should be discarded.
If you do repot on that advice, use a clean, well-draining container and suitable fresh mix. Disinfect tools between plants, avoid spreading old contaminated mix, and do not choose an oversized pot simply to give a weakened plant more room.
What a photo can and cannot show
A leaf photo can show the pattern of decline. It cannot show the condition of buried roots. For a more useful check-up, include the soil and stem base and describe how long the mix has stayed wet.
Root-rot questions
Do brown roots always mean rot?
No. Root color varies. Firm roots are different from soft, decaying roots, so consider texture and the plant’s condition rather than treating all brown roots as diseased.
Should I use a home remedy?
Avoid adding chemicals or mixing treatments before identifying the problem. Correct drainage and get advice about the damaged tissue first; there is no guaranteed quick cure for every root rot.
