Marilyn - I dunno about hostas, as I always mulch mine. But I know that you're not supposed to mulch irises 'cuz it can & will cause rot (holds too much moisture).
Rick - You have that much snow right now? Didn't think you got that much in your zone.
Margaret - GREAT idea... but won't work for me as I have too many roses that are too big. LOLL.. but should have thought of this years ago!! I kinda do the opposite.. put buckets around small delicate plants and FILL with mulch to protect from the extreme cold.
