@ CDsSister when I lived in the same city in Colorado my hostas at that time were grown in the ground did ok.
It's the hail storms that would shred some of the garden plants that made it difficult for the hostas to come back.
For winter survival for storing hostas in pots place the potted plants wrapped in bubble wrap or newspapers between a larger pot will help insulate the roots from freezing. Then place them near the house under a covered area keeping overhead frost at bay.
Once they go dormant keeping the roots protected against freezing is key. Be sure to check them weekly .
