My mother brought me a rooted piece from her Jade plant already planted in a pot. It was about 2 inches tall and growing nicely with new pieces coming in. I sat it outside to get some natural light a couple of weeks ago and forgot about it and it froze, I remembered it the next day , however it was a little too late. Now it is very ugly and dead I guess it is weak and watery feelingand darkened in color. Is there any hope left for this plant? Please help.
