We Get Sick Cactus Questions
hey there…. i was wonder if you could help me with my cactus…. we had mealie mites and i used a insecticidal soap. then this started to happened and fast. could it be corking? i don’t think its root rot. i dealt with that before. is there something we can do to save it?
thank you for any help you can provide!!!
It looks to me like you have 2 plants with the same problem. After the infestation, which the soap didn’t fix, the plants would have been susceptible to infection.
I would recommend getting the 3 of them out of that soil, and repotting the 1 healthy one on its own. You can take tip cuttings of the other 2 if you can cut above the infection. When you cut, if the flesh is clean and white then you can let it callous over for a week before planting. Since it’s winter I recommend Sulfur Dust on the cut end to help prevent fungus. If the cut end is not clean then keep cutting upward til you get to clean flesh, or if the infection is all the way through the plant then it is not saveable.
