I don't know about cuttings, but I, ummm, "divided" some small chunks off of an 'Autumn Joy' and stuck them in potting soil around June; the mother plant shows no evidence of anything having happened, and the babies grew and are flowering and will be planted into the garden shortly.

My "method" of "division" was: I yanked a bittersweet root out, and it disturbed the sedum ... I stuffed most of the plant back into the ground and watered it back in (and a few more times for like a week), but some pieces fell off; those are the ones I stuck in the spare pot and watered as needed along with the rest of the potted plants. My chunks had some root, but they were pretty puny.

You do give me the alternative which would be to simply divide and plant, foregoing the cuttings. The merit of cuttings is that get so many more.

this time of year is time to divide things... so just do it the easy way ...

the only caveat would be for peeps who might have ground heave in late winter/early spring.. and to tiny of cuttings might pop right out of the ground and freeze dry ..

but crikey... with sedum.. that probably wouldnt even matter .. just put them back in the ground ...

they are not houseplants.. and they probably have a requisite dormancy.. at least up here in my MI ... though it could probably be done under lights ... . it might not be easy bucking ma nature ... [i note you dont tell us what sedum.. other than tall...] ... its always easier to work with her.. than to try to outwit her ...

It’s an autumn joy type, which is blooming now. Still okay to divide snd move around?

I'm in CT zone 6, so close to you, and I think it's fine to divide and move now. Not so sure about cuttings (not sure they would root enough before cold). On the bright side, if you try the cuttings and lose them, you can just cut back the sedum next season and root more. After all, you'll have even more plants! I cut back my Autumn Joy about June (I think) and that's when I stick my cuttings in some potting soil to root. Which reminds me I've got to get those planted out...

Good luck!

watch out for bees though if it's blooming. I have 3 pots of Autumn Joy that I created in the spring during edit-season. I finally identified a permanent place for them to live and I was about to plant them, but too many bees. I even found a clump of weed near the pots that I wanted to pull out, but the bees kept me at bay!

I counted about 90 bees on 4 sedums out front last week, when the blooms were just opening. Then they all made tracks for the aster that was just opening up.

They bounce between the different sedum this time of year here, with occasional visits to anything else flowering. When I need to harvest the Shimmer tomatoes, I just wait for the bumblies to bumble over to the other sedum or the lavender, so I can slip in to the back of the monster tomato.
