If trying it , I would do it as soon as I could. Before flower bud was
too far along. the idea is to get plant to put energy into increases.

What seems to happen with bloomout has to do with when bud set occurs
the previous season. *If minimum temperatures at night are too warm
(or too cold) then bud set does not occur. When bud set occurs, the
increases are no longer suppressed by the main growth point (growing
tip, called apical meristem), and the increase start to grow.

If this doesn't occur, then conversion of apical meristem to flower
production occurs with vernalization. But with spring growth plant
starts producing energy for flower growth, and no plant energy towards
growth of increases. And when finishing flowering, no energy left for
the increases.

So ideas is to get plant energy to go to increases. Thus removing
flower stem. If you can remove flowering growth tip, while leaving
leaves, that would be best.

No, Chuck, I haven't. How do you mean early? Before a bud opens?
I've had bloomout fans freeze out before bloom. The fan tended to live
all summer, but never put out increase. My best luck has been to not
fiddle around with them at all. Occasionally they will put out
increase in the fall. Those I've messed with have not been a success.
I'm trying to get pods on this one, but I don't know if that might coax
any increase or not. The fan would at least probably live 'til the pod
ripened. Not sure how willing it will be to pod, either.

&gt; ÃÂ
&gt; One effect of the drought was a dearth of increase, so I'm seeing
&gt; clumps that are going to bloomout. This is one and I'm sorry
because I
&gt; like it. The cross is (At Last x Luella Dee) #1 X Energizer for
&gt; interested. It's the 2nd of only three seedlings that isn't going
&gt; further. It's not too unusual for me to be relieved to see a
clump not
&gt; attempt to bloom. There are five fans and all have stalks. Makes
&gt; a
&gt; nice show right now, but this seedling will probably be extinct
&gt; this year.
