Looks like you did a good job!
Do you have anything to mulch them with? Leaves work really well, so if you are raking any, it would probably help to put them around the plants. Leaves are free, and will be very helpful to get them through the winter, since they were divided so late in the year. Plain bark/mulch works good too, but most people don't have lots of extra mulch just laying around. I'd get some though, if it was me, and I didn't have leaves to cover them with. Lots of people use no mulch at all, and their plants do just fine, but most aren't divided this late in the year in a cold zone. They are tough plants though, so they may be just fine. If you get a lot of snow, that will also help to insulate them some.
