I needed to move some coneflowers this spring. My soil is clay so I dug them up in pieces. I was not gentle. I planted them in a new bed. Aside from them needing some extra water until they established ( about 3 weeks) they have ALL flourished. Six weeks later they are all growing and flowering. I originally had two plants and now I have six. I would say you could divide them easily with just a shovel and plant them again. It’s a free way to get more plants.
