I am in MI(
zone..6?) and have never mulched anything over for the winter. I did cover my
roses with styrofoam things so far, and cut back the peonies and piled some leaves on them. What about the rest of my garden? I don't have anything horribly fragile...perennial hibiscus, dianthus, liatrus, black eyed susans, butterfly bush,
Hollyhocks, bachelors buttons,lavendar, malva, mums and some other stuff I can't think of right now, LOL...should I be covering this stuff up with something more than just letting the leaves stay in the flowerbeds?
