Check these first

  1. Feel the soil an inch deep to see if it is soggy.
  2. Check the bottom of the pot to ensure water is draining freely.
  3. Smell the soil for a musty or rotten odor.

Likely causes

  1. Overwatering

    Most likely

    How to tell: The leaves will look wilted even when the soil is damp, and the stems may feel soft or mushy near the base. The soil might smell sour or swampy.

    What to do: Stop watering immediately and let the top 2 inches of soil dry out. If the plant does not perk up, remove it from the pot to inspect the roots for brown, mushy sections.

  2. Poor drainage

    Most likely

    How to tell: Water pools on the surface of the soil or takes a long time to drain through the pot. The plant stays heavy and waterlogged for days.

    What to do: Repot the plant into a container with drainage holes using a well-draining potting mix. Add perlite to the soil to improve airflow to the roots.

When to worry

If the stems are turning black or mushy at the base, the rot is advanced. It is normal for the plant to droop slightly if it is just thirsty, but it should recover quickly after watering.

Stopping it coming back

Always empty the saucer under the pot after watering so the plant never sits in standing water. Use a pot with plenty of drainage holes.

Questions people ask

Can I save a plant with root rot?
If the roots are still firm and white, you can save it by trimming away the dead parts and repotting in fresh soil. If the roots are black and slimy, the plant is likely too far gone.
How often should I water my Joseph's coat?
Water every 3 to 7 days, but only when the top inch of soil feels dry. Always test the soil with your finger before adding more water.
