I replanted my Christmas Cactus a few weeks ago. Purchased new cactus soil and thoroughly checked for root rot. As you can see there is hardly any root system. I went to water the other day and it tipped out of the pot. I also have leaves falling off constantly and branches almost like disintegrating. I’ve had this plant for 25 years and can’t seem to get it back healthy. Any and all tips, tricks and/or advice would be highly appreciated. Please HELP!!! 🙏🏻
