Answer: Most woody shrubs are simply pruned back when they grow too large, but flowering perennials can be dug and divided in the late fall or the early spring. Digging and dividing is fairly straightforward. Dig the entire plant up and divide by cutting through the roots, making sure that each division has both roots and stems. Replant in the garden or put the extras into containers to give away to friends. I usually dig up the plant, lay it on its side and cut through the clump with a shovel. As long as each new part has some roots and some stems attached, the divisions will be fine. You might even invite your gardening friends over to help, with the promise that they can take the extra plants home to plant in their own gardens. Best wishes with your project!
