The most important component for cultivating robust, stunning daylilies is water. During the growing season, daylilies adore water and demand around an inch of water every week. Regular rainfall will provide a large portion of the amount in many places. Your daylilies will greatly benefit from additional irrigation in locations with less regular rainfall. Additional water can be applied manually, with drip irrigation systems, or overhead using sprinklers.
How frequently do daylilies need to be watered?
There aren’t many perennial plants that are simpler to grow than daylilies. It’s a go-to for casual and experienced gardeners alike, thanks to its low-maintenance requirements and wide range of color choices. Similar to a broad-leaved ornamental grass, daylily leaves give texture to the garden when they are not in bloom.
How to Choose Daylilies
From the thousands of little yellow plants you find in office parks to the tall orange trees “Ditch lilies come in a variety of sizes and hues and are commonly found blooming beside rural roadsides. While some have distinctive colors, some kinds have ruffled petals (including purple). For season-long flowers, plant a blend of early-, mid-, and late-season kinds “Reblooming cultivars will maximize the floral power in your garden.
Where to Plant Daylilies
Daylilies are planted in large numbers along the sides of interstates for a reason—they are hardy plants! Plant daylilies in locations with six or more hours of direct sunlight each day and in soil that isn’t often wet for the best results. When planted in large groups, daylilies put on a spectacular display. They are perfect for providing color around home foundations in front of shrub plantings or to complete a perennial garden.
When to Plant Daylilies
For optimal results, plant daylilies in late spring or early fall. But if you come across a plant during a summer sale that you simply must have, bring it home right now and plant it. Simply watch it carefully and water it frequently throughout the first two weeks.
How to Prepare the Soil for Planting Daylilies
Daylilies can grow in a range of soil types, but they will grow best in slightly damp, well-drained soil that is high in organic matter. Utilize Miracle-Gro Garden Soil for Flowers to prepare fresh planting sites. The top 6 to 8 inches of native soil should be mixed with 3 inches of garden soil. Additionally, you can enhance the soil in each planting hole by mixing 50:50 Miracle-Gro Garden Soil for Flowers with the current soil. Be sure to read the section below on “How to Feed Daylilies” if you want to know how to combine the power of outstanding soil with the proper plant food for beautiful results.
How to Plant Daylilies
There are two ways to buy and sell daylilies. They occasionally arrive as bare-root plants, often known as “fans,” which are clumps of roots, leaves, and a developing stem. But the majority of daylilies are cultivated in containers. Prepare a hole that is twice as large and precisely as deep as the plant’s root system before planting either variety. If using a plant from a container, place it in the hole and then fill up the area around the roots. Make a mound in the planting hole with part of the removed soil mixture if you are planting a bare-root daylily. Place roots on top of the mound and surround them with vegetation. Make sure the plant’s crown, which is where the roots and stems meet the leaves, is just above the soil line when it is planted and not buried. Plants should be well-watered before mulch is applied to keep the soil evenly moist.
How to Water Daylilies
For the first few weeks following planting, you’ll need to water the plants every other day or so. For the remainder of the initial growth season, water once or twice per week (depending on whether or not it has rained). If your region is not experiencing drought, you shouldn’t need to water daylilies during the second growing season and beyond (4 or more weeks without measurable rainfall). Daylilies can withstand drought once they are established.
How to Feed Daylilies
Use Miracle-Gro to start feeding daylilies a month after planting. Thanks in part to natural ingredients that help nourish plants above and below the soil, Shake ‘n Feed Rose & Bloom Plant Food will help them continue to grow big and strong. Shake the food onto the ground evenly. To begin the feeding, work the fertilizer into the top 1 to 3 inches of the soil. Make sure to heed the label’s instructions regarding how much and how frequently to apply.
How to Prevent Pest Problems with Daylilies
Although daylilies often don’t cause too many issues, deer do enjoy nibbling on the blooms. Spray plants with Tomcat Deer Repellent on a regular basis (as directed on the label) if deer are a concern. They dislike the taste and smell produced by the formula made with essential oils.
How to Deadhead Daylilies
Daylily blooms do indeed only bloom for one day. The following morning, remove any dead blooms from plants to keep them clean. Cut a bloom stalk down to the ground once all of its blossoms have opened. Shear back foliage if it starts to look ragged in the middle of the summer.
How to Divide Daylilies
Plants that create clumps include daylilies. As the plants get older, clumps may get congested and produce fewer blooms. Digging up the entire plant, after flowering in the early fall, is how you divide plants. You can either use a pointed spade to cut the plant into pieces or shake the soil off and gently pry apart the roots. (The first method gives you more divisions, but the second method is quicker.) Replant immediately.

Can daylilies become overwatered?
Root rot can be facilitated by excessive water, whether from continuous rain or overwatering. Inability to absorb soil nutrients results in roots that get brown and slime rather than white and firm, which causes withering and browning of the leaves.
Planting Instructions
Daylilies need 4-6 hours of direct sunlight every day, thus they should be planted in full sun or mild shade. Even though daylilies require full sun, there are occasionally blossoms under the cover of large trees. The daylily blossoms will always face away from any shadow and upward toward the sky. Avoid high dry locations above ledges where the soil is shallow and low wet spots where water collects during rainy spells.
Any time the ground can be worked, whether it’s in the spring, summer, or fall, daylilies can be planted with great success. To avoid winter frost heaving, mulch should be applied to daylilies planted in the fall. We advise you to plant your daylilies as soon as you get them. The roots should be placed in water for an hour before planting, but, if they will be stored for several days.
Approximately the size of the pot, dig the hole. Remove the daylily from the pot, untangle the roots, and set it into the hole with the surrounding dirt tightly packed.
Until you are ready to plant, keep in a cool area. Roots should be soaked in water for an hour prior to planting if kept for several days. Create a hole and place a cone of earth inside. Cone-shaped roots should be spread out, and the crown should be slightly below ground. One inch of earth should be pressed down tightly around the plant’s crown. Give newly planted daylilies plenty of water.
The best soil is loose, loamy soil. Clay, gravel, and sand quality is very low. Compost, decaying leaves or wood chips, old manure, or almost any other organic substance can enhance poor soil.
If the daylily will be divided and replanted in a border of mixed perennial flowers in three to five years, leave a circle of 16 to 18 inches in diameter. It needs a 24–30 inch spacing if you plan to leave the daylily clump in place for 10–15 years. A border of daylily flowers follows the same rules. Daylily plants should be placed in a triangle configuration with each plant 24 inches apart from its neighbors in a landscape setting, such as a bank that will be covered in the flowers. 30 daylily plants will consequently be needed for a bank that is 100 square feet. (Add 0.304 to the square footage.) Plant the daylily seeds 12 to 18 inches apart in a straight line as an edging along a walkway.
Mulch between one and four inches thick will help keep the soil moist and prevent weeds from growing among the daylily plants. While grass clippings, leaves, hay, wood chips, and other organic materials are appropriate, their slow breakdown draws nitrogen from the soil. Particularly with recently cut wood chips, you might want to add some fertilizer. Daylilies planted in the fall should have a thick layer of mulch applied to the area the first year to keep the earth from freezing and heaving them out of the ground.
Plant nutrients are rarely insufficient in organic compost soil. Add any slow-releasing, composted organic matter, such as horse, sheep, or cow manure, or your own compost, in the spring or the fall to sustain good daylily growth.
How are daylilies maintained in good condition?
Even though mature daylilies can withstand dry circumstances, according to Myers, they bloom better in moist but not wet soil. Daylilies require roughly an inch of water per week to flourish, whether from rainfall, irrigation, or a combination of the two, according to the expert. When the weather is chilly and the soil is mulched, you will need to water less frequently; but, when the weather is hot and the soil is sandy and quickly drains, you may need to water more frequently.
Do daylilies prefer moist ground?
Problem areas in the landscape might occasionally persist despite our best efforts to restore the health of the soil. While adding organic matter to the soil is usually a good idea, selecting the right plants is another approach to deal with difficult planting locations. You can still develop thriving gardens by using hardy plants, regardless of your difficulties with compaction, clay subsoils, excessive salts, or low fertility. Not all natural ecosystems offer the best growing conditions, just as our gardens. Fortunately, nature has given us a wide variety of plants that can thrive in those challenging environments.
Fire ChiefTM Arborvitae
Here is a plant specifically designed for the Deep South. The high relative humidity and clay soils typical of many southern gardens are ideal for Fire ChiefTM. Additionally, it thrives in sandy, chalky, or loamy soils and can withstand a range of soil pHs, from acidic to alkaline. In soils where black walnut trees thrive but many other plants struggle, arborvitae thrives.
‘Orange Rocket’ Barberry
Here is a plant for tough urban environments and hot, dry places. A shrub known as “Orange Rocket” barberry is very adaptive, water-wise, and pest-free. It can withstand alkaline conditions, droughts on occasion, and clay soils. Do not plant barberry in areas with poor drainage.
& 4Spring SonataTM and Rosalinda Indian Hawthornes
Gardeners on the coast delight! The salt-tolerant plant you’ve been looking for is called Indian Hawthorne. As long as drainage is good, these hawthornes may grow in a variety of soil types and endure the extreme humidity and wind that are typical of coastal areas. Once established, these plants can withstand heat and endure drought conditions further inland.
Prime-Ark ‘Freedom’ Thornless Blackberry
One of the simplest fruits to grow in a backyard garden is blackberries. As low-maintenance as berries come, Prime-Ark “Freedom” is drought tolerant, cold hardy, and resistant to rust disease. Clay is one of the several soil types that plants may endure. Blackberries shouldn’t be overwatered as this can cause root rot.
‘Sunset Flash’ Gaillardia
Gaillardia is a stylish way to beat the heat. These hardy perennials, sometimes known as blanket flowers, are water-wise and exhibit remarkable drought tolerance once established. Gaillardia may grow in a variety of soil types and does best in sandy, unfavorable locations.
Ultra VioletTM Buddleia
Buddleia are ideally suited to dry soil conditions because they naturally grow on rocky ravines in clay, sand, or loam. In soils that range from acidic to alkaline, plants thrive. In actuality, proper drainage is one of the few soil needs for healthy buddleia.
Miss LemonTM Abelia
Abelia is a versatile landscaping shrub that thrives in challenging garden spots with seasonal variations in soil moisture. Plants can survive sporadic soil saturation, but not persistent waterlogging. You can use them in rain gardens and other places where water pools but dries out in between rainstorms. tolerant of drought once established.
CoppertopTM Sweet Viburnum
CoppertopTM is a viburnum, which are well renowned for being resilient and resistant plants. After becoming established, CoppertopTM exhibits good drought tolerance and is adaptable to a variety of soil and lighting conditions. Coastal gardeners also value the plant’s resilience to salt.
‘Chicago Apache’ Daylily
Daylilies are another plant that can survive both drought and flooding, making them ideal for rain gardens, low-lying places, and other poorly drained locations. In addition, they adapt well to sandy, weak soils. Daylily roots can be used to manage landscape run-off since they can absorb and store water. Additionally, plants can withstand seawater, making them a great option for coastal landscapes.
My daylilies are fading; why?
Root-Knot Nematode: Daylilies that are infected by root-knot nematodes (Meloidogyne species) may experience vigor loss and rapid decline. Plants that are infected slowly degrade, grow slowly, get stunted, turn yellow, wilt, and frequently perish. The signs are quite similar to those of moisture stress. Where the worms feed and inject toxins into the roots, there are frequently tiny lumps or nodules.
Sandy, wet soils are where nematodes are most prevalent. On formerly used cropland that has been converted to residential usage, they are typically more of an issue.
Prevention and treatment: Plant samples may be sent to the Clemson Plant and Pest Diagnostic Clinic through any county Clemson Extension office for confirmation if root-knot nematodes are detected in residential landscape beds. Because the root-knot nematode clearly galls plant roots, whole plant samples should be submitted rather than soil samples for tests like those for other soil nematodes.
Choosing plants that are resistant to the root-knot nematode is the best course of action. Infested plants should be removed and disposed of; they should not be added to the compost pile. Please refer to HGIC 2216, Root-Knot Nematodes in the Vegetable Garden, for more details on the signs of root-knot nematode damage and on how to control them.
Soft Rot: In the rhizomes and at the base of daylily flowers, Pectobacterium carotovorum causes bacterial rot. This soft rot-causing bacteria is a typical soil habitant. High temperatures, inadequate airflow, water retention in the soil, and insufficient fertilization all encourage the growth of the soft rot disease. Daylily plants with soft rot may have a strong, unpleasant smell coming from the crown (or base).
Treatment & Prevention: Avoiding soft rot
- By adding organic matter to heavy clay soils, you can prevent poor soil drainage (such as with composted pine bark or compost),
- Avoid regions with inadequate air circulation around plants (prune back over-hanging shrubs),
- Prevent problematic planting areas (do not plant susceptible daylily varieties in the same spot where other plants have shown soft rot symptoms),
- before sowing, let injured plants recover (cork over), and
- Plants shouldn’t be over-fertilized or over-watered (avoid over-head irrigation)
