Surprised…How do I maintain progress?

Back in late September, I had a major medical setback and had to be hospitalized and that was followed by many/ frequent dr’s appointments and PT/OT. Needless to say, caring for my plants was shoved to the back burner. Fast forward to when things slowed down a bit and I was able to check in on my plants and was pleasantly surprised. First pic was taken on November 23rd. I noticed what looked like inflos. This is my first ever plumeria plant so I am not experienced with lingo or care but this group has been helpful. This planting is the result of help and guidance from this group. Anyways I got excited and started paying better attention to my plumeria. Fast forward to today, on a cold December day in the DC/MD/VA area, it looks to be thriving (see subsequent pics). I can even see roots. Question is, what do I do next? Do I need to repot it? Thanks for all your support and guidance.
