I don't think there's anything wrong. Some plumeria wake up later than others. The fact there are claws and healthy tips is a good sign. Light is as important as warmth. The daylight length may not be long enough for them to completely waken. I would advise patience.

BTW, what you are doing is called "plunging" and is a good way to grow plumeria in colder climates. Some even dig the plant up and bare root it over the winter, which would seem more traumatic to the plants. Yet those plants revive very nicely when replanted in the spring. So I don't think your treatment caused any problems.

If you are in zone 7 it's still very early. Some of my plumies are just now waking up.

Thanks for the advice

I have so many other tropical/ sub-tropical plants actively growing that it just seems odd but hopefully growth will pick up quickly soon and maybe I'll get some inflos to form - one of the plumies was sending out a new inflo last fall before I had to abort it
