My wife has a large out door pot with Hens and Little Chicks.
If they were in the ground I would have covered them with leaves for the winter.
In the pot I have no idea how to keep their roots from freezing. The pot is far to large to bring inside.
Any advise would be appreciated.
Dig some up and put them in a smaller pot. Probaby better in a garage than a house.
Most hens and chicks are hardy to zone 3, probably zone 4 or 5 in a pot. Just don’t let them get soggy. That’s Sempervivum . Another species may be less hardy.
And don’t cover with leaves.
You could try wrapping the it in burlap - lots of it, or leaves if you could get them to stay put. Plus maybe find something more translucent to cover it.
