The temperature issues are why I put them in pots so they can be moved into the garage during our Spring sub-freezing nights. I do not like to waste a lot of effort on just a common rose. The 'Sunsprite' patio rose I bought last year is a terrific rose and worth extra effort. Last winter, I cut the bottom out of an outdoor plastic garbage can, inverted it over the trimmed rose, and filled it with cypress bark mulch. When the can was removed a couple of weeks ago, all the canes were green with some buds beginning to show. I paid $25 for it last Spring and is worth the extra effort to keep it healthy. The $3 and $5 bag roses are just throwaways if they do not perform well. I am just on the line between 5b and 6a on the state zone map so the winters bottom out at about zero degrees and we reach 100+ in July and early August. Probably not the best environment for roses.
