Nana Nadina

Asked July 5, 2013, 1:26 PM EDT

I have Nana Nadina's that appear to have some black spots on them and one of them looks like its dying. They get partial sun (mornings) and sit in well drained, mulched beds. Automatic watering twice weekly using buried soaker hoses. On this variety the leaves will curl some but these appear to be yellowing and turning brown with some black spots on the back. I am in Grand Prairie Texas where the soil is alkaline unless treated. These beds are well mulched. How should I treat these Nana Nadinas?
