Re: Christmas Cactus


Libby,
I'd be concerned about disease, virus.  Some plants can be hosts and show no
symptoms while harboring the disease that will infect others.  Some will
succumb.  Of those starts of your plant that have bounced back, some may
still harbor the problem and pass it on again in future.  I might prefer to
start fresh with a new plant.

Kitty
