my roses look horible
 

I've always had great big long lasting blooms on my White Dawn Rose.
This year, the top leaves are brown/yellow, and the blooms seem to be
rotting before they open.

Good soil, careful watering, no bugs or creatures I can see.
Live in Chicago area, weather has been normal

Anybody have an idea what's happening?
Will I loose the bush?

Please and Thank you.

Could be almost anything. If it is bug free it could be viral, but more likely a nutrient deficiency such as potassium (if for example you're on a light sandy soil) but you say your soil is good. I'd apply some sulphate of potash but don't expect a rapid turnaround.
