Plumeria will naturally start dropping their leaves ( turning yellow and usually from the bottom) because of signs of dormany. This is caused by shorter daylight; cooler temps and in the wild; reduced rain showers. They naturally start this process to conserve energy to last through the semi dormant period . The species “ Ruba” that most of us have do this most often and then some evergreen varieties ( Obtusa) will keep their leaves. Examples ( Singapore and Hong Kong cultivars) i will not worry at all when I see them doing this in late September ... I usually bring mine in around mid to late October here in Virginia Beach . They will be brought inside after I reduce watering and I also spray for bugs and use a systemic to help reduce those little critters that aren’t welcome inside the house . i use my great room and upstairs to overwinter trees . The others will be placed in the greenhouse. Remember to lift plants so they don’t sit on the floor if you store them in garage since they need airflow to keep the roots from the cold. ( keep temps in garage from going below 40 -45 degrees) wooden pallets help to lift them. Don't worry when you see those leaves turn yellow and drop... it’s all natural!! Good luck !! Laura

Very nice. Pink Pansy is a great cultivar to have. It does great in hot and full sun conditions. Once mature you can get multiple active blooms cycles per tip in a season. To the best of my recollection it has never had anything more than an occasional issue with spider mites or thrips. Also Never had sunburn issues.

It happens every so often. I know I have at least one doing it right now. Some cultivars are more prone to do it than others. I don't like it and usually remove them. My experience has been the inflo stem acts as a restrictor and the branch never matures at the same rate as the rest of the plant. So in a few years it gets pruned off and you have a one tip cutting you can root if you cut off the old inflo part. IMO a waste of resources.

Some do that, heres 4
