I inherited a Christmas Cactus from a friend of the family and am running into a problem. It was firm when I brought it home, but it had very little soil in the pot. Ever since I brought it home and repotted it, it has been getting worse and worse. I have read that they like to be a little root bound, maybe the pot is too large for it? The symptoms are that the leaves, the whole plant, is turning red and going very limp. I am using Miracle Grow Cactus Palm and Citrus soil and watering it not even once a week. This soil seems a bit difficult for me to tell when it is dry. Please help. I have always wanted a Christmas Cactus and I don't want to lose this one.
