I know when plumerias start dropping leaves, it's a sign of dormancy. No watering etc. I have a 6 foot tree, now placed indoors in front of a sunny south facing window. It has three branches from the bottom old trunk, sort of like a crepe myrtle would do? The two smaller branches have lost all their leaves in obvious dormancy. But the one tall branch has most of it's leaves still, 12-15 of them. It lost maybe 4-5 leaves from the bottom but that was all/ Do I treat this plant as if it is dormant? Or do I water it because the main tall branch has leaves? Thanks in advance.

Leaves of the tallest branch:



Leaves of the going-dormant other two branches:



Here are the three branches at the base, two of which have lost or losing leaves:

Plumeria go dormant at different rates; in my yard I have many with no leaves at all and quite a few with still all their leaves. Treat it like a growing plant.

Thank you, Hetty. These branches are on the same plant. They go dormant at different rates on the same plant?

Hmmmmm no - that is odd. Not sure what to suggest. Water lightly I would think and keep an eye on them.

LOL OK. I didn't mean to stump you twice in one day. btw, any thoughts on the partially broken branches on my other plant?

Am I in trouble? Now I have determined that the plant that looked half dormant and half not, stumping our expert for watering suggestions has indeed been attacked by red spider mites. So explains why only parts of the branches were losing leaves while the others thrived I never saw the insects, the leaves just dropped off. My bad! I have treated it as if it were dormant and not watered it all this time while it has been in the house. Have I killed it?? I am going to move the plants back outside after next week. We have one night predicted at 37* other than than it is good weather to get them acclimated to the outdoors once again. Hints? Suggestions?

I'm new in the plummie world, but I will try to answer this. Lack of watering during winter time doesn't normally kill a plumeria. Check if the bottom part of the stem is still hard, if it is, this should perk back right away in Spring when you start the regular watering/feeding schedule. Check the tips, I read somewhere, that a shiny tip is a healthy tip. Spider mites caused damaged to the leaves of my Dwarf Pink Singapore plants I kept indoors but now that our weather is warmer and I brought these plants outside, they are looking healthy again, with no signs of spider mites. The leaves where the spider mites feasted look pale/washed out green though but other leaves are healthy green.

I'm new to plumerias. My two babies have started to go dormant. They've lost all their leaves but the stems are solid.
My question is how to treat them for pests while in dormancy? I've had spider mite issues before and treated them with neem oil and/or insecticide with good albeit temporary success.
If I store them in my garage (I live in SW Florida) should I still treat for mites? And how?
I've also read that the plants shouldn't be stored on the concrete floor directly, as this could harm the roots. Any suggestions would be greatly appreciated.

Welcome @Plumeria_Newbie to the plumeria forum. Usually I have less issues with pests or spider mites when my plumerias are dormant. Since you are in SWFL even winter time you might still get warm weather so you can just spray the tips with water to blast the spider mites but don't let the pots get soggy wet.

I am in zone 9b so I keep my plumerias outdoor and the only time I get them covered is when we have below 40s forecast. You can check your zip code here for your zone:
