Hey. I did the same with my cutting. I found some rot so I cut a bit higher up, I left it out for a week but then I noticed some new rot. I decided to pot it anyway. I watered it only once and then left it on the router as I don't have a heat mat. Now all leaves have turned black so I guess it's doomed. Shame cos it had a rare burgundy flower color. Oh well. The other plumeria I have has stopped growing but that's OK. I have only 66F indoors so I guess it's chilly for them.
We are having a mini summer now, temperatures are around 72 F and it's sunny and humid, so I took all my potted plants outdoors. The good weather will last a week. My plumeria is sunbathing right now. My two crotons are growing fast and so is my tropical hibiscus who is also sunbathing now. Alocasias are stuck though. I think I'll take one bulb out of the soil and let it dry out and overwinter it in some dark corner, then pot it again in spring. The other one I'll put under grow lights and see if it starts growing again. I'll also increase indoor temperature to 70F. More than that will cost me a fortune in electricity...
Kentia is growing a new leaf. Delonix regia doesn't grow.
