3. Divide & Plant
With a sharp garden knife or hand pruning tool, cut through the crown. Be careful that each section has one strong, healthy tuberous root and 3 to 5 eyes. Then dig a shallow hole and place the divided sections into the hole with the eyes facing upward. Cover with about 1.5 inches of soil, keeping your “new” sections spaced about 3 feet apart. Don’t plant to deeply, or you’ll find a reduction in blooms. After planting, water thoroughly. Keep the soil moist until the ground freezes, and then apply about 4 inches of mulch for protection and insulation. Be aware that your divided plants may take a couple of years to begin blooming, but you’ll be richly rewarded with the gorgeous flowers for years.
