It is typical for plumerias to lose their leaves in winter. Keep it in a warm place and water very sparingly (or not at all) until you see the tips turn a brighter, shiny green. Increase watering as new leaves develop, but let it go dry between watering. If you can, get it outside once the danger of frost is passed. Nice plant!

Thank you! I have some hope restored! I was getting nervous 😮‍💨

I agree with the other comments too. I planted my Plumeria clippings in the Spring after storing them in a dry and dark shed over the winter and the cuts where completely calloused by spring. I planted (5) Plumerias in-ground, 2 to 3 feet apart because at the time I didn't know any better, but they still bloomed during the first warm season. Of course they went dormant over the winter but now it's spring again and they are just starting to bloom again as the weather is getting warmer. I live in SoCal where we experience summers at over 100 degree ferenheit and winters under 50 degrees ferenheit. I am amazed that my plants have survive their first year in-ground. Tip: Feed your Plumerias with used coffee grounds every 3 weeks or so, and water it 2 to 3 times per week over the hot summer and watch it bloom! Just remember that these plants go dormant during the winter.

Thank you! Your plant is beautiful!
