This is the way I choose where to cut the stalk. After blooming, perhaps in a month or so, the stalk will die back a certain amount. It could be 2/3 from the tip or 1/2 from the tip, but the die-back portion will be brown and brittle. I just cut an inch or so below this die-back point. Not very scientific but it seems to work. I have three old stalks and there are at least one new branch on two of them and at least two new brances on one of them, plus the new stalk from the base of the plant. It looks like I will have a minimum of five blooming stalks in the spring. Should be a nice show! Ken
