How do I fix root rot in my sesame plant?

It is less common for sesame to develop root rot unless the soil stays soggy for too long. This issue is usually caused by poor drainage or overwatering. Check the soil moisture and root health first.

Check these first

  1. Feel the soil an inch deep to see if it is constantly wet.
  2. Inspect the drainage holes to ensure they are not blocked.
  3. Gently lift the plant to check if the roots look white and firm or brown and slimy.

Likely causes

  1. Overwatering

    Most likely

    How to tell: The leaves turn yellow and wilt even though the soil feels wet. If you pull the plant gently, it may come out of the soil easily because the roots have decayed.

    What to do: Stop watering immediately and allow the top 2 inches of soil to dry out completely. If the rot is severe, repot the plant into fresh, well draining soil after trimming away the mushy, brown roots.

  2. Poor Drainage

    Possible

    How to tell: Water sits on the surface of the soil for a long time after watering. The pot may lack drainage holes, causing water to pool at the bottom.

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

When to worry

Worry if the stem base feels soft or mushy, as this often indicates the rot has spread to the main structure. It is normal for the plant to wilt slightly if it is just thirsty, but it should recover quickly after watering.

Stopping it coming back

Always wait until the top inch of soil is dry before watering again, and never let the pot sit in a saucer of standing water.
