Powder puff tree prunning
Powderpuff or Calliandra blooms on new growth in the spring and through the summer. A light prune (removing no more then 1/3 of the plant) might be helpful.
Thanks for the question.
I don't know if my question got to you but I am sending you the picture of what I already pruned
I had it done by a landscaper who is also a horticulturist about 6 months ago and she took everything off and only left the main branches
That is quite the prune. If it has been 6 months, I would expect flowering to occur next season since the plant probably went through some shock with an extreme prune.
