Why don't you just keep the pots
outside some where near the house.

Provided roses experience continous cold they
adapt fairly easily to it. I have 35+ roses in pot in
my concrete patio. They are near the house
but I measured -16 F tempretures this winter there.

I have not lost one yet. Though they have had an extended
acclimitization period and 6"-12" of snow.

If your roses have already leafed out and you are afraid of
frost get those rose cones and plunk them on top when
it seems to get cold.

Your aim is to make the tempreture as even as possible.
not too hot or cold. It is those swings that cause the most damage.

My better local garden stores have their best selection of potted-up roses
in late March/Early April (zone 6a). But our last frost date is not until
May 15. So every year I play this game where I dig the holes, put new
roses
in, pot and all, and watch the weather like a hawk, ready to move all the
new ones into the garage attached to our house (unheated) at night, then
being made somewhat late for work by waiting until the temps are above 30
or
so to put them back out again, sometimes having to leave them in the
garage,
just for one day (seems not to have any negative effect).

Questions:

(1) I've read that anything below 28 degrees F will do damage. So I bring
the plants into the garage whenever the forecast is for 34 or lower,
figuring that will cover any local microclimate issues. Am I being too
conservative?

(2) Is there some better solution I'm missing? It's tiring to move a
dozen
pots back and forth on a daily basis.
