Good Morning Linda,
Thank you for contacting the U of M Extension Service.
Please click on the following link about dividing perennials: https://extension.umn.edu/planting-and-growing-guides/dividing-perennials
This information states:
Divide spring and summer blooming perennials in the fall because
- There is less gardening work to do in the fall compared with spring.
- It is easy to locate the plants that need dividing.
- Perennials with fleshy roots such as peonies (Paeonia spp.), Oriental poppy (Papaver orientale) and Siberian iris (Iris siberica) are best divided in the fall.
- When dividing plants in the fall, time it for four to six weeks before the ground freezes for the plants roots to become established. This is particularly important in colder, northern climates.
Wait until fall to do your transplanting.
Good Luck!
