I currently have a toadstool that is attached at the base to a piece of PVC pipe. The coral has grown into two separate stalks and they both have heads on them about 6 inches across. Question is how do I split off one of the stalks so I can have two separate specimens. I have never propagated a coral before, do I just cut off one of the stalks right at the base? or is there a different better way to go about it?
