Cinta I have very similar experiences with the wetness (not the freezing part) and finally just began covering them during winter because I could never get good enough drainage, or when I did get it, in the summer they dried out too quickly. Covering them isn't very pretty but it saves them! I try to cover as late in the season as possible, for me this year it was November, and then I plan to uncover them as soon as possible in the spring, last year the one bed I covered, I uncovered by February (again this is for my conditions. I think with your wet, freeze, wet conditions it is tricky!
