Gardenality.com's Answer · At our nursery and garden center in Zone 8, we leave containerized Drift and Knock Out Roses outdoors all winter long and rarely if ever lose one to the cold. If you're in Zone 8 the Drift Rose should be fine in the container on your back deck. If temperatures are going to drop below 20 degrees F, to be on the safe side, you could always bring it indoors until temperatures rise. It's a good practice to water the rose, and other plants, when severe cold weather is coming. This causes water to freeze around the roots, insulating them. If the soil is left dry, the roots could literally become freeze dried. Hope this info was helpful. - Brent)
