| Fine-rooted orchids like oncidiums do best when potted in a medium like fine bark or sphag. Brown roots may not be dead, just discolored from the bark medium. I wouldn't cut off anything that isn't obviously dead. As Aniko says, your plant should be fine since you're repotting it during a period on new growth. The main roots that are important are the ones on the new pseudobulbs, anyway. |
