i left mine as is last winter. i'm a zone 5, but according to angela's thingi, a zone 6. what's yours? its not listed. ~medo

I'm what's called a "zone 5a" IE, cold as a zone 5, but with unreliable snow cover.

I would definitely mulch them with straw or pine needles (something that won't mat down and harden) and leave it on until new growth shows in the spring.
