Why is my Coral Cactus getting mushy and soft?

Root rot is the most common issue for Coral Cactus because they hate sitting in damp soil. Check the base of your plant immediately to see if the stems feel soft or look discolored.

Check these first

  1. Press the base of the stems to check for softness.
  2. Stick your finger two inches into the soil to feel for moisture.
  3. Inspect the drainage holes to ensure they are not blocked.

Likely causes

  1. Overwatering

    Most likely

    How to tell: The base of the plant turns brown or black and feels squishy to the touch.

    What to do: Stop watering immediately and let the soil dry out completely. If the rot has spread, you may need to repot the plant into fresh, dry cactus mix after cutting away any black, mushy roots.

  2. Poor Drainage

    Possible

    How to tell: The soil stays wet for more than a few days after watering.

    What to do: Ensure your pot has drainage holes at the bottom. Use a gritty, well-draining soil mix specifically for cacti and succulents to prevent water from pooling.

When to worry

If the base is soft and mushy, the plant is in serious danger. If the stems are firm, you are likely just dealing with a minor watering error.

Stopping it coming back

Always wait until the soil is bone dry before giving your plant a drink. Use a terracotta pot to help the soil dry out faster.
