winter preparation

Hello. I have a raised wood flower bed (lined on the inside with garden fabric). In it I have planted lavender, blanket flower and seedum. Im not sure how to prepare this container for winter…Should i cut back the flowers?…

Wisteria

I live in Toronto and would like to plant wisteria in a large pot against a wooden fence. It has partial shade. Are these conditions not conducive to blooming? How much success will I have? Thanks…
