Fall Transplant
Fall is a good time to transplant perennials.
Start by cutting the plant back to within 4 to 6 inches of the base. It is inevitable that plant roots will be damaged when a plant is dug. Cutting the top growth back will ease transplant shock and make the plant easier to work with. Use a garden spade and dig all the way around the plant. Next gently lift the plant and place in a suitable container. Move the plant directly to another location. Remove the plant from the container and place in a hole that is the same depth as the plant was originally planted. If you are not going to replant right away use potting mix to fill in around the plant roots and water well.
I use this same procedure for an annual Lantana that I keep over the winter in my greenhouse.
