How do I fix root rot on my Chinese elm?

Root rot is less common for this plant and usually occurs when the soil stays soggy for too long, often due to poor drainage. Check the roots for a mushy texture and a foul smell.

Check these first

  1. Check if the soil is waterlogged or muddy.
  2. Smell the soil for a sour or rotten odor.
  3. Gently lift the tree from the pot to inspect the root color.

Likely causes

  1. Overwatering

    Possible

    How to tell: The soil remains wet for days and the leaves may turn yellow before falling off.

    What to do: Stop watering immediately and let the soil dry out. If the tree does not recover, repot it into fresh, well draining soil and trim away any black, mushy roots.

  2. Poor Drainage

    Possible

    How to tell: Water pools at the bottom of the pot or the drainage holes are blocked.

    What to do: Ensure the pot has adequate drainage holes. Use a gritty, fast draining soil mix to prevent water from sitting around the roots.

When to worry

If the roots are black and slimy, the tree is in serious trouble. It is normal for a few older leaves to yellow occasionally, but mass leaf drop is a warning sign.

Stopping it coming back

Always empty the saucer after watering and ensure the soil dries to the top inch before adding more water.
