Disease susceptibility: Powdery Mildew
You aint kidding, it's terrible, I had a climber that was knocked over in a terrible windstorm, a year or two later up came this sprig, it's now spread to the trellis we built it around my patio, and it's full of powdery mildew.
For anyone else that has this growing, i suggest getting rid of it entirely, it's been a nightmare and has spread to all my 65 rose bushes.
By the way I live in zone 08a.

I am not usually an organic gardener unless I find something that works pretty quick. I had PM on Crepe Myrtles several years because of too much shade & sometimes too much rain in spring. One year I sprinkled a good amount of old corn meal (with weavils) around the base of them. They never got PM again. I just had sprayed it once before that.......and usually it took several sprays until they cleared up before weather got hot. I use corn meal around several shrubs now, prone to disease. It just hasn't cured black spot on my rose! :).

When I moved into my house this plant mysteriously appeared on the NORTH side of my house. I didn't know anything about roses at the time and I just let it grow. Looking back, I know now that last year (year two) it had a bad case of PM, but it still put on a good show. This year it is over 15ft tall, and 8ft wide. Since it only gets morning sun I'm surprised I've got over 100 buds on it. I suspect it was the rootstock of someone's failed rose bush. How lucky! The amout of roses and the vigour of this bush makes the PM something to be overlooked. I suspect with adequate sunlight this bush may do even better for me. I will finally prune after this years flush. Wish me luck!

I'll certainly wish you luck! Dr. Huey is a very pretty rose when it is grown in the right conditions. Powdery mildew is often caused by lack of air circulation, so when you do your prune this year, make sure you lace the plant so that it can have better air circulation. Pay special attention to the part of the rose next to the wall.
Smiles,

I have had no trouble with excessive PM on this rose. Both are in shady areas--one in denser shade. I just hit it with a fungicide if I have a little left over in my sprayer afte spraying my other roses. After it blooms, I cut out all canes except for the new ones. Maybe that extra air somehow takes care of the PM. Since it only blooms once, I keep threatening to get rid of it. However, it is gorgeous when it blooms so I just keep it.

I can second the Disease susceptibility comment. It is a mildew magnet when it's in part shade. Funnily, some people comment that it tolerate shade! However if it is in full Sun and dry climate, it's OK.
Rooting it requires good light, early morning Sun is best if rooting outdoor and misting is likely required if not done in Autumn or early Spring.
The ability to heal with callus is excellent. Chip budding is a pleasure on this understock as the sucess rate is excellent. Roses do not seem to have a lot of vigor on this rootstock. It's suitable to make standard because of the big size, straight cane and medium vigor for the budded roses. Even lateral shoots from a big 2yr basal can be used to make standards because they are simply huge!
