Re: CULT: Bloom-out


Here is something you might want to try.

There is some thought that there are many growth points along the side 
of a mother rhizome and that the growth point that puts up the 
bloomstalk and new leaves (the meristem)also puts out an inhibitor that 
keeps the growth points from turning into increases.

So, you might take one or two of the bloom stalks off *now*, being sure 
to cut it off low enoough to get the meristem. The theory being that the 
lack of the growth inhibitor will allow other increases to form.

I know of a number of growers that routinely take a rz, slice it into 
quarters or more, plant the pieces and end up with a lot of plants. They 
normally do this at the time that they dig and replant, but cutting off 
the bloomstalk might just work now to save the plant. All you would be 
sacrificing would be a bloom stalk and it sounds like you have almost 
nothing to loose.
