Please help my kalanchoe
This was my first ever plant so she's precious to me. It was doing great and was flowering constantly but then had a bad thrips infestation. It took a while but I managed to get rid of them but it got her really stressed. For some time she didn't even have one leaf. But she started to push new leaves and I was really happy but then this happened.
The part in the photo was black today. I don't think it was like this a week ago but I'm not sure when it started. I scratched the black part and it looks like this. Should I cut? Is she dying? I checked her roots and they are fine. How can the stem rot like that. My city is really moist could that be a reason?
Overall what should I do? I'm scared of cutting her please help.
It's in front of a large southeast looking window. I water her on average once in ten days.
