Usually there is no need to trim, but if old roots, diseased roots, and rotted roots appear, they need to be trimmed in time, keeping only the healthy roots. If they are not trimmed in time, it will affect the absorption of nutrients by the other roots.

Whether or not the roots are trimmed, orchids need to be disinfected.
