I have been cultivating bonsai for a while but this is my first black pine so I am looking for guidance as I understand they are specifics to that specie. Here is a short recap and where I am at: the tree was field grown- planted in pumice for a couple years- in a he fall of 2019 I plucked needles to 10-12 pairs on all the buds to let the plant grown freely and well fertilized in 2020
So I am wandering what is the next course of action?
Is it time to cut branches to the new buds?
Is it time to select two terminal buds on bud/branch with multiples?
Do I wire branches to stimulate more back budding?
I plan to start fertilizing in March until mid may and stop until September, is it the right schedule for this stage of development?
Here are a few pics of the plant from afar and closer to show inner buds
