Trimming Sour Oranges into Hedge

[JCINAZ]

I have a new hedge I am attempting to grow of about 20 sour orange trees. I planted them about 2 years ago, they are not fully grown. They are growing nicely, but I am not trimming them and probably should be to encourage hedge type growth.

I read this on the internet:
Use pruners to remove any thick branches or suckers that form a second trunk. Snip them off where they meet the main trunk of the hedge tree. This kind of pruning is more severe than maintenance pruning and should be done in the winter or early spring.

I have multiple trees with 2 trunks, one is pointing straight up the other is leaning out. As a rule should I just lop off the non-straight trunk?

What else should I be doing to trim them now that spring is here?

Thank you.

If the leaning branch will be inside of the hedge when it's full, just leave it. Any branches that are long and whippy should be cut back by half to make them bushier. If you want them to grow faster, apply an all-purpose fertilizer now and again on the frequency stated on the label.

Any branches that are long and whippy should be cut back by half to make them bushier.

Does this advice apply to all (Left/right) long/whippy branches or just the ones that come straight out? (Front/Back)

All of them, even the top.
