I think your best bet is LST if possible otherwise...like I said work the stalk in beetween your finger's until it's like pulpy and starts to fall over on it's own from were you sqeezed it.
when it hangs 90 degree's to the side,it will just heal and stay like that.If you do this do it high up enough that the wieght of the top cola wont brake the whole thing in half.imp:
