A few branches on my plumeria plant have some soft spongy areas up toward the flowers. What is this? What can I do to help the plant? I don’t over water the plant and always from the bottom of the plant not on the flowers.

It looks like a fungal issue, likely verticulim wilt. This is caused by overly wet soil, or watering too often without letting it dry out thoroughly down to 3 or 4 inches for this plant. They will not tolerate wet roots without a good dry out between each watering.

This will have to be treated with a fungicide. This article will help: https://www.gardeningknowhow.com/garden-how-to/info/using-fungicides-in-garden.htm

It would also be beneficial to put a tablespoon of dolomitic lime and a teaspoon of wettable sulfur around the root zone. This will help to remove the infection from the soil. Do this once or twice per year for added protection.
