Phals: do you cut back the part of the aerial roots that are dry?

[Piao Liang]

Hi, before I came to this forum, I was not misting the aerial roots of my Phals and some of them became very dry. This happened with very long ones and they dried half way. I know that normally you do not touch the aerial roots but if you cut back the dry part, will the other part grow again?

In my opinion, if you mist the air roots and they do not turn green with the addition of moisture then they are typically dead roots and I cut them back. The other way to tell is healthy air root are firm and not wrinkled.

I agree, I cut back very wrinkled parts.

If they are firm but don't turn green with water then sometimes it's because that root is unused to absorbing a lot of water at once, I've seen healthy aerial roots where the water just rolls off them like a duck's back. Soaking the same bit of root for a while usually causes it to finally turn green though and turning green is a sign it's alive.
