New black eyed Susan not doing well in part shade.

Question

Plant wilting. Only “fail” this year! Leaves and flowers drooping 2 weeks after planting. Not in full sun.

Answer 1

If you're not seeing powdery mildew on the plants, there are two possibilities that come to mind. Your plants like a neutral pH soil, so if you've fertilized them, it may be too rich for them. The other possibility is that they may be wanting more sun.
