Asian daylilies are low maintenance perennials that adapt to many different temperatures and soils. They are hardy in zones 3 to 9, which is almost the entire United States. Each flower blooms for one day, which is why they are called daylilies, but there are many blooms on the plant that flower one after another. Planting Asian daylilies is not difficult as long as you know the correct environment in which to plant them.
Things You’ll Need
- Manure or compost
- Pruning clippers
- Choose an area in the late summer in full sun with moist, well-drained soil. Work the soil a foot deep for each daylily, incorporating organic matter such as compost or manure into the soil as you dig.
- Dig holes for each plant wide enough so the roots can lay flat without bending. Space multiple daylilies 18 to 24 inches apart. Place the crown, where the roots meet the stem, no more than 1 inch below the surface of the soil. Backfill the soil around the roots and tamp it down.
- Water thoroughly after planting to help settle the dirt around the roots. Place a 2- to 3-inch layer of mulch around the bases of the plants to keep down weeds, help retain water and protect against frost.
- Cut off the tops of the Asian daylilies with pruning clippers within 4 to 6 inches of the soil to promote growth for next season.
