My sister has a Thorns of Christ that she has left outside in direct sunlight with no water. The prickly parts are soft and the branches are brown and were soggy. I have the plant now and I am wondering is there any hope of saving it. This is what I have done so far: I have soaked it for 30 minutes in room temp. water. I repotted it with fresh dirt and gave it plenty of water along with food. I also keep it inside sitting on a stand by the window so it may get sunlight.
