To frag it you can rubber band pieces of stalk to rubble or plugs(tight enough to hold but not so tight the rubber and cuts it), place cuttings in tray with rubble, toothpick through the flesh and rubber band toothpick to rubble, use a needle and fishing line through the flesh and tie around rubble.
I usually rubber bad a piece of rubble to it will still in tank before cutting. Wait a few weeks and it usually attaches there and then I cut the frag off
