mine are in a big planter that I take inside for the winter and water once in a while in the basement.
this year I also took inside my planters with lemon balm, lavender and thyme. I know they dry out even if I water but hopefully will stick around until the spring. My rosemary survived last winter inside on a window sill and I put back outside last summer and back inside now! Alberta zone 3.
