The "moisture" that is feeding the mold is from the caudex .... the caudex is the plants storage reservoir
As long as the cut moist fleshy areas are exposed, the loss of moisture will continue - until the cut areas heal or harden over
Might try hydrogen peroxide
First - if you have a bottle of hydrogen peroxide .... confirm the label (active ingredient) is either 3% or 9% hydrogen peroxide
