How far back do I cut my Black Eyed Susan plants so they will come back next year?
I have a brand new garden landscape installed in May and mt job now is to take care of it. But I don't know how to prepare the plants for the winter. Southern Oregon

You can cut back this plant about halfway or more once it has finished blooming, removing spent flower stalks, and a second bloom might occur in late fall. In fall, you can cut this perennial back to 2 inches above the soil line if the plant is diseased or you consider the dead stems unattractive.
