I had to move some perennials out of our north garden this past spring. We had to put in a new seepage bed, so I lost the east half of the north garden. As long as I had to move them I decided I might as well divide them at the same time. Here are some pictures I took of dividing the day lilies.

Digging around a plant with the shovel. Cut all the way
around the plant and underneath as deep as you can get.

With the half clump flat side down, dividing again

Lilies with the tools used. Some of my favorites, the wheelbarrow, sod lifter and watering can. Also some pots I got from a neighbor which I have used many times for transplanting and for covering small plants when there is a danger of frost.
The lilies were dug up and divided on March 25th. Some were divided in half, some into quarters. These were plants from some of our master gardener plant exchanges and some I moved from my Mom’s garden. several years ago. They spent a little over two weeks in the pots, sitting on carts.
April 10th. The lilies re-planted in their new row
Notice the 100ft measuring tape. They are planted 2 foot on center.
The lilies did not bloom much this summer, which I am blaming on the stress of moving and a very dry summer. I am looking forward to them having a more colorful year.

What a great tutorial, Karen. I have a few daylilies that could use spltting next Spring. Thank you for the guidance.
Oh, to have your beautiful, loamy soil! When I divided mine several years ago I had to use an axe to divide!
