This is Holly, she's a notocactus magnificus or green pumpkin cactus. Today I put her outside in the shade so she can get some some light. I came home and found out somebody stole her pot and her rocks, they just left her there with the roots exposed!!! I immediately repotted her and I noticed her base near her roots are turning white! Is my cactus rotting? I can't figure out what it is, she does feel a bit soft at the white part.

They must have liked your pot. Grumbling

Is the side that was down also white like that?

If the white part is hard to the touch, it may be corking. Corking happens on older cactus (yours doesn't look that old) and it is usually tan, not white. But, unless its soft, I wouldn't worry about it. Don't plant your cactus too deep - none of the body should be buried in soil, just resting on top.

Here is a photo of one of mine, showing the corking at the base. BTW, the accepted name is now Parodia magnifica. Smiling

Soft at base ? Could be root rot.
To much water. You've. Got to let them starve for water ! Till they start to shrivel.
Now ! Hears, your only chance ! Pull her out of pot. Shake off soil from roots. Leave her dry out for 5 to 7 days. Plant her in some barely dampened soil, of, "Equal parts of, potting soil, and washed sand."
Leave her for a week, before, watering. And bottom water her.

And ! Remember ! With, cactus and succulents ! Torcher toucher tourcher ! Its hard to kill them ! Except !
If you water them to much !

Philip, Did you read from the beginning?

Someone stole the pot and left the cactus.

Lzuo hasn't answered the question about soft or hard.

Easy boy. Take a deep breath and breathe. Rolling on the floor laughing

Hi Daisy and Philip, I appreciate both of your replies! I am afraid she is a bit soft at the base. I try scraping the surface and I accidentally poked her hole into her!! 😱😱
Does that mean she's rotting then? Can she still be saved? Do I need to re root? Please let me know what to do guys! Thanks

If the bottom (white part) is soft, yes its rotting. Repotting will not help.
