Daylilies are difficult to start at home. Visit your local nursery and buy a few starter plants. If you know another gardener in the process of dividing daylilies, ask if they’d be willing to share some of their root divisions with you.  Root divisions are created when multi-stemmed plants are pulled apart to form single stems. Daylilies are vigorous growers and often used as ground cover. They will spread and form a dense mat after a few seasons. Daylilies prefer full sun, although they will tolerate partial shade. To get the most blooms, choose a location that receives a minimum of 6 hours of direct sunlight each day. However, daylilies can easily handle 8 to 12 hours of full sun daily. Daylilies planted in the shade will bloom less frequently. Daylilies are hardy and can withstand almost any kind of soil, but they thrive in well-drained soil. To test your soil's drainage, dig a hole that is 1 ft (30 cm) wide and 1 ft (30 cm) deep. Fill the hole with water. If the water drains in 10 minutes or less, you have well-draining soil. If it takes an hour or more, your soil drainage is poor. To amend soil that drains poorly, add some organic matter like well-rotted manure, wood chips, pea gravel, or peat moss. Mix it into the existing soil thoroughly. Daylilies like slightly acidic soil. Purchase a soil testing kit from your local nursery and perform a reading by following the included instructions. Anything under 7 is considered acidic. Anything above 7 is considered alkaline.  To reduce acidity in your soil, add garden limestone. To reduce alkalinity, amend the soil with sulfur, gypsum, or sphagnum peat moss.

Summary:
Purchase nursery-grown starter plants or obtain root divisions. Choose a site that gets at least 6 hours of full sun daily. Select an area with soil that drains well. Test the soil for a pH between 6 and 7.
