You can definitely pick out one of the candles in blue or let one of them just run and the other just break it to give energy to the tree.
I would also just pull some of the needles on top portion if you want to keep the stuff in the red and vigorous.
The stuff in the red I would cut back hard just keep lots of needles buds and terminals buds for the future.
I’ll take a picture of one I have. To give you an idea.
Looks super healthy.
Around June you can cut candles of the smaller lower stuff to divide.
I would not decandle the top portion of the tree.
You can also wire the whole trunk of the tree if you want to change something or just let it thicken.
I fertilize heavily. I use a commercials fertilizer that is 15-15-15 and I use this on young material it’s granular form. Then I’ll feed kelp and fish emulsion I try for once a week during growing season but if not twice a month and then I’ll supplement with an organic like dr earth or something like that.
Dec 2023 maintenance
Reduce new growth needles (8-10 pairs upper half; 10-12 pairs lower half)
Select a Sacrifice branch—don’t reduce needles on this branch
Example from Joshua Diaz
what I did with one of mine: I keep a lot of needles and options towards the base, wire some of the lower branches and then I have like a ladder
almost where the one I. Yellow I might wire and that one might take over once the trunk gets thickness but it could serve as my secondary sacrifice branch.
