Well this has stumped me a bit lately. All the info ive been trying to find seems to not be thorough enough so i know what to do.
What i wanted to do i get this pine from a friend

Im thinking i will air layer the right branch (our right)
But then once that branch is established im a bit confused about how i can cut the growth back. How can i encourage the growth back closer to the trunk? Or is the plant too far gone and needs to be pruned properly by reducing the end foliage from a younger age? Keep in mind im a beginner, i love pines but man they are confusing....
Just need some advice
