Should I cut my Coreopsis and Center Glow Ninebark (Physocarpus opulifolius) back in the fall? If yes, how far to the ground? I live in upstate New York, Syracuse. Thank You!

The Ninebark shrub does not need regular pruning.
Here is a link with more information.
The Coreopsis can either be allowed to die back naturally or can be cut back to about 3 inches in height for the winter.
