New roses from mid summer suddenly turning yellow from within.
I bought these shrub roses from a local nursery about two months ago. They are planted in full sun in my garden. Our soil is pretty heavy on clay but the side areas drain well. We are currently in a drought and I've been trying to keep everyone watered but it's difficult. I have two roses planted near each other and both are turning yellow from their inner leaves, but both pictures are of the worst looking bush.
They were fed with a slow release food upon planting and top dressed with compost. I'm new to roses and clearly am failing these ones somehow. How can I help them?
