Hello Everyone! This is my first post! I’m new to gardening. I inherited a variety of cactus at the house I moved into. They apparently had been neglected for quite awhile. I would love to bring them back to health if possible. I am attaching photos of the cactus that looks most poorly. I’m not sure what species it is exactly and what issue it is fighting? It appears to have areas with rot or scale maybe? It does have healthy looking new growths which gives me hope. Should I try to propagate the new growths or is the “mama” salvageable? Any advice would be greatly appreciated. Have a wonderful day! - Nicole 🌵
