I'll have to update photos tomorrow. Not sure what happened although I have never posted anything before It is a learning curve.

Sometimes the wrinkled branches are an indicator of being root bound. I would start by checking the root ball (laying down and gently sliding out of container...is that a clay pot? it may not be possible then), checking drain holes on the containers to ensure they are not clogged. If I didn't see anything odd I would then give them a good watering as the soil looks pretty dry.

For comparison purposes my temps can range into the 100s as well and I am watering 4 times per week by drip irrigation. In my opinion, in South Texas, in a full sun location, I cannot over water a Plumeria during the months of July and August unless I threw it in the pool or plugged up the drain holes.

Thank you I will try that and I also purchased a water meter I am hoping this will help. I was checking my other plumeria and they are doing the Same thing really soft and almost mushy branches the main trunk is fine. I am so worried I am the going to lose all my beloved trees.

I will definitely not be scared of watering more than three times week. I was worried that I was over watering.

thank you so much any other suggestions would be helpful.

You are welcome. Over watering is an issue for many people with young plants but its becoming quite apparent under-watering of more mature plants is almost as common. It changes over time too.

LOTS of variables (temps, geographic location, Conditions, age of plant,size of container, and quality of soil) have an impact so there is not an empirical answer which fits everyone. IOW a person must experiment and find their own.

Thankbyou
