As I was repotting this morning, I noticed the velamen (sp) was off some of my Maxillaria roots. (This is the topic of a future post). However, I just repotted it and went on to an Oncidium and saw the same thing, again, I potted and went on. There was no obvious mushy rot. I have often read to pot and that the inner 'strings' hold the plant in place. So, maybe a root discussion would help new comers. I know I could learn more.
