Q.How Do I Prepare A Coneflower For Winter?
This is my first attempt at a perennial garden, and I want to make sure that I take care of my coneflowers this fall. Any advice you can give me would be greatly appreciated.

Most cultivars are hardy in your area, and some are even hardy down to zone 2 or 3!
They are quite well adapted to growing without intervention, so no action will need to be taken.

I read that article before I posted this question. It doesn’t really tell me if I need to cut the plant down in the fall and possibly cover it with mulch? Do I just leave it alone?
