It could be that this part of the yard remains more moist. These plants need zero watering after the first season. Being a xeriscape plant. it prefers poor, dry soils. They are prone to disease if they are planted in moist areas.

I would be sure to hold off on feeding, and do not water, at all. You may want to use a fungicide on them, as well.
