Plenty of good advice I think I am about ready to operate.
As I do not know a lot about gardening in general I do whatever seems to make sense
which usually works ok for me. This plant is one I do not want to screw up, its my wife's so When the top is removed can I just put it in the new soil. That is what i do with my outside Opuntia ( I am only now learning these names) and they just keep on growing.
I have been reading here about letting a plant dry and root before cutting which does have me confused as what to do.
