This beautiful cactus was my motherās, itās about 40 +years old, got sickly looking a couple weeks ago, Does anyone have a tip? I know she needs no water, had a break near the root, tried to winch it together, hoping it might heal, but still not doing very good. in a glass pot with no drainage, Iām afraid to repot it as I donāt want to traumatize it any further š¤·āāļø
