Black tip? Looks like it to me.

Stem rot? Was this from the black tip one cut back?

thanks for the embed Dave! 2nd pic is from (repeated) cutbacks. Every time I've cut back it seems like the stem just ends up getting soft below the cutback - tho the plant does try to heal it closed quickly so I guess it's at least showing signs of life. Have had it for years and it finally bloomed last year, would be bummed if I can't save it. Any advice on what I'm doing wrong or should try is very much welcomed

I think I'll try the suggestions from this thread

Thanks, had seen that before and is why I originally cut the top off to get below the rot. Went out today to try doing the suggestions in the thread I posted above but it was too far gone - in some parts it was hollow in the middle, in others it was like mud and there were some worms(?) in it. Sad, grew it from a little stick for 8 years, finally flowered last year.

try to keep cutting back until you see clear white bark...no even a small piece of brown...It is rotting..

There is good news! If you can find the white bark no matter how far back you have to cut it....you will get more branches, which in time will give you more blooms..

give it 1/2 tsp. plant epsom salt per gallon distilled water (of course dont give it the whole gallon) but enough to lightly water the soil.

hope this helps...:)

Thanks for the advice, sadly it was too late for my plumeria :( Looking for another one now though and will definitely keep that advice handy in case I run into the same issue!
