I repotted a Phaelenopsis into fresh bark about a week ago. It’s a small plant and evidently doesn’t weigh very much, because as the roots are growing, they’re pushing the stem of the plant up out of the pot. The tops of the roots are emerging above the bark, too. I realize now I could have pinned it in place while the roots restablished, but too late for that.
Should I repot it again, reburying the roots and pinning it down? Or should I just let it go and not worry about it? I’m inclined towards the latter; after all, new roots grow from up the stem and their tops are inherently exposed above the potting media. So that makes me think it’s probably not a big deal for it to be up out of the pot a bit.
I suggest you let it go. Orchids don’t like to be disturbed once they start to grow roots. Phals roots usually grow roots outside the media, but if you notice all the roots try to go out the pot, it means it needs more moist in the growing media.
