Repotting beginner encounters boatloads of moss

[JasperBuddy]

Note: I was going to attach pics, but I need to figure out how to reduce file size. Yikes! I'll add them later if can.

This is my first repotting endeavor with a plant I bought last year.

It was the first that bloomed again! Long story I won't bore you with.

Anyway, I bought it at King Soopers or some other chain store. Not sure what I expected, but I had to cut the plastic pot off. It was packed with moss. There were a lot of dead roots. I was surprised it bloomed again and has produced more leaves since my purchase.

One thing I noticed is that many of the roots I removed looked fine at the end. It was closer to the plant that roots were black and mushy. Is that normal?

I'm going to put all of them (I have 2 others bought more recently) in bark.

Thanks! Steph
