Q.Coral Vine Withering Overnight
I bought coral vines and put them on my cement balcony. mostly sun during the day, temps in the 90s lately. I bought plants one week apart. literally overnight each of them withered in turn. I hadn’t repotted them; I added a nutrient stick to restore the soil but otherwise left them alone. the third one is doing fine.

They may have needed more water. 90 degrees on a cement balcony could do them in quickly. The photo was blurry so I couldn't get any information from it.
