Hi!

I've overwintered 35 roses in large Costco pots in my heated/temp controlled garage. Many are starting to put out growth now.

I'd like to put them all outside on my driveway. But I'm not sure if the nighttime temperatures are too low. I live in Calgary and the day time temperatures are going to be above 10C. A few nights may get as low as -2C.

If I get a large tarp to put over them at night, do you think I could bring them out now?

What if we get snow?

I'm really confused as to when to take them out.

Thanks for your help!

Carol
