    Divide daylilies (also known as Day Lily) any time from early spring to the middle of fall. The very best time to divide daylilies is late summer after they have finished blooming.

    Prepare the spot where you will plant the new divisions. Loosen the soil and dig a hole deep enough to cover the base of the new clumps. Daylilies grow well in almost any soil in the full sun.

    Remove any mulch that may be around the daylily clump.

    Use a garden fork and begin digging about 6 to 12 inches (15 to 30 cm) from the base of the clump. Dig all the way around and under the daylily clump. Remove the clump from the ground completely.

    Shake any loose dirt from the daylily clump. This will help you to see where to make your divisions. The best places to divide are areas where the foliage is weak.

    Separate the daylily clump in half with two garden forks or with a garden shovel. Make other divisions with a garden fork or a small garden spade to suit your needs. You can keep the divisions larger, or you can further divide into individual fans. The fans can then be planted close together to fill in areas of your garden.

    Cut the foliage of the daylilies back to around 12 inches (30 cm). This step is not necessary, but it will make the plants easier to handle.

    Place the divided clumps or fans into holes you have previously prepared. The hole needs to be a few inches larger than the clump, but not too deep. Cover the area around the plant with soil. Be careful not to cover the crown of the plants with too much soil. Pat the soil down around the plants.

    Add mulch around the base of the daylilies. The mulch will keep grass from growing around the plants, and it will help to hold in moisture.

    Water the daylilies well. Keep the plants watered through the coming weeks.
