These Crassula ovata plants were given to my other a few weeks ago. I didn't pay any attention to them until today. I think they were all green when she got them. They were left outside in the frost, rain etc. I see a few green leaves on some of them. I took one out and the roots looked okay.
I'm thinking that I need to repot into cactus mix with one pot per plant.
Not sure if it were too much water, or what was the issue. The plants were all kept outside prior to her receiving them.
