Phal potted to high above potting medium?

[Becca]

Hi everyone. I have a question in regards to a phal I just repotted for a friend's friend. I repotted my friends orchid for her yesterday at her house and one of her other friends found out I was stopping by for this purpose and dropped off her orchid as well. It is her friends orchid I am concerned about as I didn't know I would be repotting it and didn't bring enough materials for it. Here is the background info.

It was grocery store phal in a ceramic container with no drain holes packed tightly in sphagnum moss only. It had several good roots, one looked like it was in active growth. So we tossed the old medium and trimmed the bad roots. I only had one pot size it would fit into but wasn't thrilled with it because it was still a little large depth wise for it and I didn't have any more packing peanuts available. It was a 4 inch square pot and I really had to squeeze the roots into the pot to fit the square shape since it was previously in a round container. I used repotme.com's imperial phal mix which contains sphagnum moss, Monterrey pine bark, cork chunks and perlite.

By the time I was finished the phal was sitting above the top of the pot with about a half inch to an inch of the top of the roots exposed before they were covered by potting medium. This is my concern, that a phal being ropotted at this time of the year, adapted to pure sphagnum moss has root exposure and a more open potting medium. I don't want her orchid to die and offered to take it home and fix it after my friend checks with her friend. Maybe I'm just worrying for nothing, but I thought I would check with everyone on here. I don't have any pictures since I left the orchid with my friend. All opinions and advice are wlecome! Should I try and get the orchid to repot with the roots further down or will it be ok until spring when it is best to repot?
