As I see it, roses need half a day's sunshine every day ideally. And to be fed, fed and fed. Soil to be good and to be moisture retentive.
Erica, your site does not sound ideal at all, does it?
I will be planting a new rose tomorrow....the soil is good sandy loam and enriched with compost with added fish blood and bone, so a balanced fertiliser. It will be in a sunny spot.
For me, anything that flowers a lot needs to be fed a lot. A high potash feed then once a month or so during summer
Can you move your roses to a sunnier situation? And if you can try to add some compost of sorts to your clay soil.
