Root rot signs, rescue steps, and when to repot

Root rot happens when roots stay oxygen-starved in wet soil. Early action matters: stop watering, inspect the roots, remove decayed tissue, and reset the plant in a mix that dries correctly.

What You May See

Look at the whole plant before deciding on a fix. The age of the affected leaves, whether the soil is wet or dry, and how quickly the symptom appeared all help separate normal adjustment from an active care problem.

  • Wilting even when soil is wet
  • Yellow leaves with soft stems
  • Sour smell from the pot
  • Black or mushy roots
  • Soil that remains damp for many days

Visual Checks

Compare this symptom image with the affected leaves, roots, soil surface, or growth pattern on your plant. Use it as a visual reference, then confirm the cause with the checks below before changing care.

Likely Causes

Match the symptom to the plant's recent care history. The same leaf problem can come from different causes, especially when light, soil moisture, temperature, repotting, and fertilizer changed around the same time.

CheckDense soil with poor aeration
CheckOversized pot holding excess moisture
CheckBlocked drainage holes
CheckLow light reducing water use

First Checks

Do these checks before buying treatments or repotting. A few minutes of inspection can prevent the common mistake of watering a plant with damaged roots, fertilizing a stressed plant, or moving a low-light plant straight into harsh sun.

  1. Slip the plant from the pot and inspect root color and texture.
  2. Check whether the potting mix is dense, muddy, or sour.
  3. Look for healthy firm roots before deciding how much to prune.
  4. Compare pot size to the actual root ball.

What To Do Next

Choose the step that matches what you confirmed. If more than one cause seems possible, start with the least disruptive correction and watch new growth, root condition, and drying time for signs of recovery.

  1. Remove mushy roots with clean pruners.
  2. Repot into fresh airy mix and a pot with drainage.
  3. Move the plant into brighter indirect light while it recovers.
  4. Water lightly after repotting, then wait for the mix to dry appropriately.

What To Avoid

  • Do not leave the plant in the same sour mix.
  • Do not up-pot a plant with a reduced root system.
  • Do not fertilize until new growth shows recovery.
