It's about a year old and had been doing well. Suddenly it lost all it's leaves and now this. It's a cutting off my mom's plant and I want very much to save it if possible. Thank you for any advice you may have.
It sounds like stem rot. I am growing several cuttings too and that is always a worry at this young stage. The only thing I read to save it is to cut off the top that is not affected and try to root it again.
Not overwatering is critical in the beginning. It is very easy to lose cuttings this way. Even when you don't think you've overwatered.
Research says you can try a liquid fungicide in the soil, but most experts say there is no going back once root or stem rot has set in.
If they are dark and very soft you may want to go ahead and try to root the part that isn't rotting before it moves all the way up.
There is lots of information about growing plumarias on society websites like the Plumaria Society of America or the Southern California Plumeria Society. The nurseries that sell plumarias also have growing information on their websites. And there are many You Tube videos.

I started the Plumeria from a 4" piece. It is now 6 ' tall with two branches. Of course, I have to move it indoors when temps fall to 50 degrees. I won't have to do that in Texas. Please advise. Thank you so much.
You can take cuttings and store them till next spring. Here is how:

Is epsom salts beneficial to add to soil for planting Plumeria cuttings? If so how much salts should be added to the soil?
When first growing cuttings, you are concentrating on growing roots and leaves. Once your plant has developed roots and is growing nicely, start fertilizing. It is then you may need some epsom salts to neutralize the soil if constant fertilization raises the acidity level too high. The articles below explain:

It has brown spots on the leaves and it is really special to me and I don't want to lose the plant. Please help. Thank you very much!
Your plant may have contracted a disease or pest. Check out this article: https://www.gardeningknowhow.com/ornamental/flowers/plumeria/pest-control-for-plumerias.htm
You'll need to give the plant a good cleansing with an insecticidal soap, neem oil, or even rubbing alcohol on a cotton ball.
