Thanks Kittiekat for this advise. I will try this and hope it will help!

Hi Kittiekat,

I cut it down to the root but its the same color through the whole cactus.

Do you think its still consumable?

I cut the cactus open. I had two with the same problem. Now one looks normal inside with a white flesh color. The flesh of the other cactus is not white anymore but greyish color. Is it still good?

See the pic i added...

Hoping for your replies...

Yes it could be that the stem is plump with water. Good to know that its not a disease. I'll cut it off and put it in a dry place. hope it will grow again.

Thanks for your answers. I will cut the rotten part off the plant.

It didn't get really cold, previous winters it was colder. I am not sure how this happened.

So, i should just cut the sick part off and then it will grow again?
