Hi friends! Well, I was doing the weekly watering, and got my Onc. over to the sink and just was curious as to how the bigger pseudobulb was doing... so I gently felt it, and it went squish. Eeew. So, I removed it from the plant (which now looks
like this). Anyway, why generally, would an older backbulb/pseudobulb rot like that?
I have had this plant for about 3 weeks and realize that I have this over potted, and will fix it today

but at the time I got it, I didn't have anything other than this one.
