I would say go ahead and remove the keikis as the posted videos show you and then repot the mother plant. If she still has thick, green roots in her pot she could still be salvageable. I don't necessarily associate an overproduction of keikis with a damaged mother plant, but that is something I did not give much consideration to
King. Glad you mentioned it
