I also realised recently that multiple grow also happen to my shark teeth but not as many. Last month, I split my shark teeth rhizome into 2, recently and the older rhizome has only about 4 existing traps, they look very weak but probably due to stress of repoting and splitting. I feed a bug to the last open trap and now there seems to be 4-5 little greens poking out of the soil. I also don't know if it was the feeding or summer's magic.
