Chin Cactus · Gymnocalycium mihanovichii

Why is my Chin Cactus getting soft and mushy?

Root rot is the most common issue for Gymnocalycium, usually caused by sitting in soggy soil. Check the base of your cactus first to see if it feels squishy or discolored.

Check these first

  1. Press gently on the base of the cactus to check for softness.
  2. Stick a wooden skewer into the soil to see if it comes out damp.
  3. Inspect the drainage hole to ensure it is not blocked.

Likely causes

  1. Overwatering

    Most likely

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

    What to do: Stop watering immediately. Remove the cactus from its pot, trim away any black or mushy roots, and repot it in fresh, dry cactus mix. Wait 7 to 10 days before giving it a tiny sip of water.

  2. Poor Drainage

    Possible

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

    What to do: Ensure your pot has large drainage holes at the bottom. Use a gritty, well draining cactus soil mix that contains perlite or pumice to help water move through quickly.

When to worry

If the entire base is soft and the plant is leaning, it is likely too late to save. Some minor discoloration at the very bottom can sometimes be normal aging.

Stopping it coming back

Only water when the soil is bone dry throughout the pot, which usually takes 14 to 21 days.
