On second thought I would recommend a different venue. If you want black spot resistant roses try either some of the Bucks noted for bs resistance or check out Palatine roses' website for the new disease resistant Kordes roses. If you are new to roses, I would recommend Palatine because they deliver huge bare roots that will do well in their first year. Then check out Chamblee's for Buck's - those will be one gallon potted plants and will need time to mature but how soon they mature also depends on the variety. I rooted a Folksinger cutting last winter and by the end of the growing season it was 4' tall. On the other hand, I got Quietness as a rooted seedling beforehand and it is still about 2'. I know that the mature height of Quietness is about 5'. Earth Song is said to be blackspot free, great bloomer and fragrant but I have no idea how fast it will mature - I just got it from Chamblee's. But again, to those who just start with roses I recommend to get great quality grafted plants to have satisfaction of growing roses relatively fast. You could also check out Pickering nurseries, they also list a large number of disease resistant roses. http://www.pickeringnurseries.com/ I would suggest a rose you didn't mention and that is Compassion - healthy, fragrant, good repeat and gorgeous. It is a climber but I grow it as a large shrub. Here is a link that might be useful: Palatine roses

I wouldn't bother going to the trouble of cutting it down -- unless that's the first step in the process of digging it out. If you want to grow a climbing rose, make your choices from either: 1. "Large-Flowered Climbers" -- that is to say roses that are climbers from the git-go -- NOT climbing sports of bush roses (like Cl. Q.E.). The latter as a group are not generous bloomers. 2. Tea-Noisettes (officially Noisettes) -- These babies love to climb, but they are great bloomers, and very fragrant. It's my understanding that they're pretty disease-free in your area. You might take a day trip up to the Brenham area, to visit the Antique Rose Emporium. A wander around their display gardens inspires. And use the HelpMeFind web site to find likely climbing roses. Use the Search, then Advanced-Search function, and look for Large-Flowered Climbers. You can literally spend hours in that digital "Wish Book."

It is almost guaranteed that any plant of QE you might encounter is virused, since it was released into commerce in that condition. If you just want to experiment with budding onto QE, there's no reason not to, as long as you make the assumption that anything you bud onto it will end up virused, as that is a likely outcome.

As far as I understand from what you wrote, is that you planted these roses last year in spring. And they were potted plants? I have found new potted plants will perform wonderfully there first year. They usually come in really nice soil with fertilizer. But depending on winter, they can be set right back even with protection. It can take another season or two to get them to be more vigorous & put on some size. And sometimes you can have a rose do great for multiple seasons and then one winter can really do it in. Hope they continue to grow for you and good luck!
