If conditions are right, you are going to get bs. Our temps have been cooler and we've actually had rain this summer, and I've seen bs on roses that have always been clean for me. I consider it just to be an odd year. However, I did notice yesterday, that most of the HTs are still clean.
HTs do very well in my climate, but there are other roses that get far more bs. It usually depends on how long a spring we have because it is more humid during the spring period than it is during summer months.
