How do you prepare hostas for winter?
Hostas need little care for over wintering. You can take the effort to cut off all the brown leaves as they die to keep bacteria from making it to the main part of the plant but I have yet to do anything special other than let the top growth die and it comes back every spring. I do add a few inches of mulch on top to insure the plant from freezing. I live in zone 7-8, if you live in a northern climate, I would either dig up the plant if you have lost some to the cold in the past or use 6 inches of mulch to protect the underground plant over winter.
