Late summer into fall is a great time to divide and move perennials. Maybe a plant is just not quite in the right place, or plants have become overcrowded and are no longer thriving. Be sure to carefully dig up as much of the root as possible, and if dividing, be sure each division has three to five strong stems and healthy roots. Select the new location and dig a hole wide enough so that the roots are not crowded, and be sure the plant is at the same depth as it was previously. Add a little compost or soil amendment if needed, but do not fertilize. Water thoroughly and mulch with a couple of inches of loose organic material, such as bark chips or leaves.
