Remember; the rhizome only blooms once. The making of increases is a timing thing (I think-my uneducated guess)and I am not sure that removing the stalk will signal the plant to start putting all its energy in increases. I would guess my average of the last 5 years at better than 50% (I would hazard a 60/40 ratio). I have had some bloom in the 3rd year, so some are just more finicky about being moved about.
