Does anyone know what's going on with this? Not a watering issue.

It’s supposedly has to with overwatering. I had it happen to a little Mexican Fence Post after bottom-watering too many times…I think.

That's what I thought but I don't see how it was overwatered. I don't water my cacti until they're bone dry and I haven't had a problem with any of the others. Any idea what I can do about the black?

Mine just sort of imploded, starting with the black spot. I believe the issue with mine was “environmental” plus I treated it several times for mealies. (It looked like this).

Saving it…yeah, cut those tops.

#### MummaDeb replied on 2025-02-09

Going to do that today. I've had corking happen from stress before but not black spots. 🤷‍♀️

I'm thinking over-watering would cause rotting at the base rather than at the top. Too high of humidity can be a problem because then bacteria can grow at the top. Some people just cut the rotted part off so that it doesn't travel down the plant.

### KJM commented on 2025-02-08

I've never had to do that, cut the top of the plant off I just read about someone doing it.

#### MummaDeb replied on 2025-02-09

Think I'm going to attempt that today. Thanks.
