Joe, you're techinally in a different zone than I am, I'm in 7a up here, but what I did last year (late November) was to dig holes in my half empty vegetable plot and plop the pots into the ground for the winter, and placed some shredded pine bark mulch around the canes. I also drug some of my potted roses into an unheated, dark garage and they did splendidly too. Something like that might work for your hanging baskets.

Miniature roses are generally grown on their own roots and are more winter hardy than full sized roses despite their delicate appearance.

I would think they'd be totally fine in your zones although I'm in a zone warmer.
