Cutting Back False Sunflowers

Question

I recently transplanted some of my false sunflowers (rudbekia). Some are really tall and I was wondering if I can cut them back. If so, would they branch out and get fuller?

Answer 1

You can trim anywhere from 50-75 percent of the plant back. This should help encourage additional branching, making the plant fuller. You'll also want to keep it well watered during this time, which will help the plant bounce back.
