Yes I agree......... Mine only gets Rain water... but
mine lost a 'super' new root (1.5 inches) in the care of carers when I was away for 7 weeks this last december.. it did not turn black but just became hollow.
I am lucky my plant has continued to grow leaves and a new root and I have a frozen bud... The "trick" as usual is check those roots and make sure some are functional.... the rest follows..patience is needed..
