We visited Hawaii and I purchased 2 plumeria cuttings. I followed the directions on the packaging and placed the ends in water changing daily. One of them developed rot quite quickly and despite my best efforts and cutting it back to fresh wood several times it "passed away". The second one is thriving with multiple large leaves but I am not getting any roots. I am afraid if I put it in soil it will die. Should I leave it in the water and pray for roots (it has been in water since the end of September) or should I place it in soil and hope for the best?
