Spicy Devil Ninebark Dying

Hello My spicy devil Ninebarks has white powdery mildew and the branches are turning woody. The leaves are also curling up and drying out. How can I save it? I’ve been doing full sun to light shade and keeping it evenly moist.

Podosphaera aphanis, which is the powdery mildew that will infect ninebarks can be controlled with peroxide or need oil, but prevention is necessary. Without removing thee extra moisture from the equation it is bound to happen again.

Let's get to the watering part.These shrubs are drought tolerant, but not wet tolerant. These will want a good dry out. I would let them get dry down to at least halfway down the container between watering. They don't tend to tolerate soil that stays moist, unless this is a new planting in ground. Even then, they will not thrive in moist soils after recovering.

ONce the watering issue IS corrected, it will be easier to maintain control of the infestation.
