From my limited experience, they will straighten out a bit over time, but they don't return back to 100%

How long where they under the snowload before you brushed it off? With heavy snow loads I find it's best to brush it off right away, as soon as you can. Sometimes also wet snow freezes onto the branches/foliage and removing it at that point causes more damage.

One trick I was taught but never tried is to tie arbs with a fishing line - you won't see it from a distance and it helps the branches hold together under heavier snows.

You might find this video of value:

Most of the multi trunk arbs in this country are held together with plastic plant ribbon or soft nylon cord. Dark or green colored. It's inside the foliage around the trunks so doesn't show on the out side. After the plant starts to put out spring growth, it pretty much will stay the way it is so if it doesn't straighten itself out by then, tying it together some is about all you can do.

Is the trunk leaning coming right out of the ground or does the lean start higher up? If the former, it will need staking and straightening. If the latter, it may be ok but a few pix would help.

20 foot emerald greens???

in my experience.. they will come back part way ... but still probably look like heck ... most likely ... removal will end your pain ... and you would start with removing the bent ones.. and see if the rest will will fill back in in a few years ...

the problem with these trees.. is the multiple trunks.. which allow a dead zone between them.. so snow accumulates because the wind hesitates .. and as they splay further.. more snow accumulates ... this is one reason we suggest that you buy and maintain single leader trees .... which shed snow ...of course.. when they come with the house.. and have been there for decades.. there is nothing to do about them ...

when this has happened in my garden.. i have removed them .. eventually ... sooner or later.. i got tired of looking at them ...

I brushed the snow off first thing this morning. It snowed all day n night til around 11:00 pm.

the first pic is the trunk coming out of the ground. Leaning, the 2 nd pic is the same arb

The last pic's trees will be fine, the first pic will need real tending to when the ground thaws. In the mean time you may want to support it in the event of another nor'easter.

i'll tell you one thing.. ive had two national hosta tours in my yard ... and a regional conifer tour ...

do you think they ran to all the perfect specimens....????

noooooo .. they ran to all the weirdos .. lol .. mostly things damage by the wicked witch of the north.. ma nature ...

just relax ... in mid to late summer.. after a few adult beverages ... start to wonder.. if they arent ... like.. totally amusing ... and a plus in your garden ...

WHO SAID THEY ALL HAVE TO BE SOLDERS AT ATTENTION ???

PS: i like the second pic.. the angle of the dangle.. and all that ... HEY.. you pointing at me????

20 foot emerald greens???

And so the myth that this is a small growing variety pops up here yet again.
