What to do about roots

[bobloes]

Hi All,

I have three types of orchid and it is the phalaenopsis that is the reason for my question. Following the advice I have been given on this forum they are doing well. The phal roots take up maybe a thrid of the pot at the bottom and is starting to produce aerial roots. So I think there are two questions.

When (how do I decide) should I repot and should I always go up a size?

The aerial roots are not particularly attractive. Can I just cut them off at the point where they emerge from the pot?

Basic stuff I am sure but grateful for more guidance.

Thanks

Bob
