Phalenopsis roots just starting to grow out of pot holes

[Ebee90]

Hi all! I only have started with orchids within the last year and only Phalenopsis, but I seem to have things going well as they all have nice healthy root and leaf growth. I've told myself no more through until I can make sure I'm adept enough to get them to rebloom. Ha!

My smallest Phalenopsis is a grocery store survivor, when I repotted him, there was only two viable roots, and they were not very long. So I potted him in a 4 inch pot as that still seemed plenty of room for such dwindly roots. Well six months later and I have root tips growing through my pot holes. I really don't want to cut up this pot and that is the only advice I've found so far. Should I go ahead and repot him into bigger pot already? Should I try pushing the roots back into the pot? What happens if they break off (purposefully or by accident)?

Thanks for any advice!
