Location: Daylilies need more than four to six hours of direct sunlight to grow and bloom. They thrive in most soil types; stay away from those that are frequently damp. Organic matter addition will enhance plant growth in extremely sandy or clay-rich soils. The pH range for soil is 5.8 to 7.0. To achieve a pH of 6.2, request lime recommendations when submitting a soil test.
Daylilies can be divided or planted effectively at any time of the growing season, if necessary. Early planting is necessary to give plants time to develop a strong root system before winter. Our greatest planting seasons in eastern Virginia are from early spring (April 1) through early fall (September 15), but not during extended stretches of extremely hot and dry weather. Daylilies can be relocated when they are in bloom, but removing extra foliage and flower stalks can help the relocation go more smoothly.
For planting, prepare the soil to a depth of 12 inches by working it into a friable state. You could want to include organic matter into the soil. Create a 12-inch-square hole. With soil, create a mound in the middle of the hole. Place the plant atop the mound and wrap the mound with the roots. One inch below the soil’s surface should be the maximum depth at which roots and leaves converge. Put soil over the roots, press it down, and water it.
Use mulch to retain moisture and keep weeds at bay by using pine straw, used sawdust, decomposed leaves or grass clippings, wood chips, etc. After it has settled, your mulch should be between one and two inches thick. Mulch also offers protection during the winter.
Water your plants to prevent wilting. Just before and during the blossoming season, water as needed. In the summer, avoid watering newly planted daylilies when it’s hot outside. Alternatively, water your plants well when you do and add moisture as needed in the morning or colder evening.
Fertilization: Fertilize once or twice a year, at the very least. Pick a fertilizer that is balanced, such as 8-8-8, 10-6-12, or 10-10-10. Splitting the fertilizer application or utilizing a slow release formulation, especially in sandy soils, may result in more satisfying growth. Since fertilizers react acidically, it is advisable to take a soil sample every three to four years to check the pH of the soil.
Which month should daylilies be planted?
There aren’t many perennial plants that are simpler to grow than daylilies. Due of its low maintenance requirements and extensive color options, it is a favorite of both novice and seasoned gardeners. 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.

Daylilies can be planted at any time of the year.
Why are daylilies grown? Low Maintenance – They grow tolerantly and without much effort, even in the most difficult circumstances.
Great Value: When it comes to initial perennial plant investments, daylilies are the finest choice.
Daylilies can be found in old, deserted cellar holes of New England homesteads. Daylilies are still flourishing there 150 years after they were first planted. In order to ensure speedy establishment and the best bloom, we will supply huge divisions. The plants will be examined by the state, labeled, and prepared for planting in your garden.
Will my daylilies blossom if I move them? Even after being moved early in the spring, a clump of daylilies will continue to bloom that year virtually as if nothing had happened.
When should I sow? Daylilies can be transplanted at any time of the growing season. Many individuals decide to transplant their plants in the spring or early fall, giving them plenty of time to settle in before the following flowering season. Daylilies can endure being divided in the sweltering summertime.
What should I do if I can’t immediately plant my bare root plants? If you just received them, open the packaging right away and let them air out. Plants should be kept cool and moist, but not soggy. They can be kept out of the ground for up to two weeks, but the season’s bloom can be lost.
I haven’t drawn out a permanent garden plan. Is it possible to temporarily plant daylilies before moving them? Yes, you can relocate daylilies at any point during the growing season. For a season or two, think about putting them near the perimeter of your food garden. They will immediately grow greater cluster sizes thanks to the additional fertilizer and water. The clump will be ready to function if you move it intact to a less ideal location later.
How much sun do daylilies require? The amount of bloom is directly related to the amount of sunlight. In other words, daylilies will thrive in any light condition, but the more sun, the more blossoms. Think about how much of the day they would receive direct sunshine when deciding where to put them. The strongest sun occurs in the midday and early afternoon, but morning sun is typically sufficient for a good performance.
Which type of soil is ideal for growing daylilies? Daylilies can be grown in almost any soil, however their performance is higher in richer soil. A pH that is balanced and the soil is friable and humus-rich are ideal. When making improvements, use compost, and fertilize occasionally.
How deep should they be? Plant 6–8 plants “Depending on the root mass, deep. Once the hole is ready, set the daylily upright in it without trying to cram it inside. Loosley fill the hole nearly to the top with earth, covering the roots. Without obscuring the green of the crown, tamp down the earth around the roots. Leave about a half-inch-deep depression, or water reservoir, all around the plant “deep.
Should daylilies be watered? Water is the best fertilizer for daylilies, according to Dr. Darrow. Even if compost is the best soil amendment for nutrients, you should think about providing daylilies regular waterings to encourage their growth. Extra water results in more blooms and a longer bloom season, barring really rainy conditions.
Does Virginia have daylilies?
Daylilies are noteworthy, with well over 85,500 varieties developed and registered in the last century! The scientific name for this perennial, Hemerocallis, which translates to “beauty for a day,” gives rise to its common name, daylily. But do not panic, there are still at least six more days worth of blossoms to come on each scape (flower stalk). A healthy clump will therefore bloom for roughly two weeks if it has six buds per scape. Today’s hybridizers strive for at least 20 buds per scape, which prolongs the bloom period. There are daylily types for every stage of the flowering season, which runs from May through September. Even a daylily I had in November flowered again! Early July is prime time in Central Virginia.
The daylily’s slogan, “You’ve come a long way baby!,” is appropriate. A few common daylily species have been hybridized to produce extravagant, vibrant blooms that have earned them the nickname “the poor man’s orchid.” The majority of you must be familiar with the traditional orange “roadside daylily,” Hemerocallis fulva, which is native to Asia and is sterile like its relative “Kwanzo.” H. fulva, which came to this area with the 18th-century settlers, has marched its way over our continent by putting out shoots, or stolons. It can easily crowd out perennials or other daylilies if planted in a bed with them. Even a diligent gardener may frequently miss certain stolons that will start growing in another area of their or their neighbor’s bed.
An H. fulva variation and the 18 other viable species, all of which originated in Asia, are the sources of our current hybrids (mainly China, Korea and Japan). The current daylily is credited to Dr. Arlow A. Stout, who worked at the New York Botanical Gardens from 1911 until 1947. His first cultivar, “Mikado,” which was produced from a complex of daylily species that included a subspecies of H. fulva, was released in 1929. Daylilies currently grow in all regions of the United States, depending on the type, but do best in USDA Hardiness Zones 4 through 9.
A fan is the name given to each daylily plant. Roots, a crown, a scape (flower stalk), tall, slender green foliage, buds, and blooms are all characteristics of daylilies. The flower, which has a female pistil and a male stamen, is where the crosses that produce seeds for new plants are produced. On the scape beneath the blossom, a little plant known as a proliferation can occasionally be seen (similar to the baby plants of a spider plant). In order to create a plant (clone) that is identical to the mother plant, proliferations can be rooted. While the proliferation is still on the scape, little roots frequently develop and occasionally a flower is created. In this instance, trim the scape three inches above the proliferation and below the proliferation. Plant the cutting in a pot with the small roots slightly visible above the surface (ideally with rooting hormone). A new clone will develop, but when it returns the following year, it will only be the size of a seedling.
For their desired crosses, hybridizers first create paper labels or a tagging system. They transport pollen to the end of the pistil early in the morning, before the bees have had much time, but after pollen has dried (in the center of each flower). The cross is then used to identify the blossom on the parent plant. The plants in a hybridizer’s garden can have labels dangling from them in every direction!
For individuals who want to grow more of their favorite cultivar, it is important to understand the fundamentals of hybrids. Daylilies that are hybrids easily produce seeds, but because they are hybrids, the young plant won’t be true to the parent plant. Daylilies must therefore be divided in order to produce a cultivar that is identical to the original. When a sizable clump of lilies forms from their roots’ ‘clonal’ growth, the plant is pulled out and the several plants are divided. The cluster should ideally be divided into two or three fans, which are then planted. The optimal time to divide plants is in the late summer or very early fall when there is still time for the new plants to establish roots before winter. If you plant in the spring, make sure to mulch the plants thoroughly and give them plenty of water at least once a week. Plant divisions are often sent to you bare-rooted by growers. They should have their foliage pruned back to a height of roughly 67 inches, and they should soak for an hour.
Dig a hole that is deep and has a mound of earth in the middle before planting a daylily. After placing the roots on top of the mound, cover them. If the plants are in a pot, make sure the crown is level with the soil. If daylilies are planted too deeply, they won’t blossom well. Water the area around the hole thoroughly so that the water drains and the earth settles back over the roots. Put the plant’s name in PENCIL on a plastic marker. Marker-made labels typically deteriorate. Mulch the lilies well after the first fall freeze to prevent the freezes from killing their roots.
Neutral soil is preferred by daylilies (pH 6.5 -7.0). They thrive on soil that has been thoroughly treated with compost or manure and grow well in Virginia clay. Give daylilies a growing space of at least 18 inches. Daylilies do best when planted in full sun, especially the lighter-colored varieties. Give reds and purples some midday shade because they tend to smooth off in the heat. Daylilies should be mulched in the summer once they are established. They require the mulch to help retain water so that they can blossom well because they detest heated roots. It’s time to divide the daylily clump when the plants are growing on top of one another and there are fewer flowers from one year to the next. You might need to use a fork, shovel, or garden knife to cut plants apart if they won’t separate readily. Replant as if it were a bare-rooted plant after cutting the foliage back to 68 inches. Give away the remainder and replant them in clusters of two or three next to one another.
There are three types of foliage habits for daylilies: dormant (DOR), which dies back in the winter; evergreen (EV), which stays green all winter (there are hardy evergreens, but most evergreens prefer the warmer states); and semi-evergreen (SEV), which dies back in the cold winters but stays green in warmer climates.
Additionally, there are three different times that daylilies bloom: throughout the day from dawn to dark; at night from early afternoon till the following morning or afternoon; and for at least 16 hours so into the evening. The lilies that bloom until dusk can be utilized as cut flowers, particularly if the bud on the scape is mature. Extra Early (EE), Early (E), Early Midseason (EM), Midseason (M), Late Midseason (LM), Late (L), and Very Late are the different daylily seasons (VL). (5)
However, no “true blue (lacking purple tones)” and no pure white colors have yet been discovered. Hybridizers have changed the species lily into daylilies with a very wide variety of colors with good color saturation. They are eyed, striped, ruffled, pleated, sculpted, picoteeed, edged, and more. Daylilies typically have three petals and three sepals, although certain varieties, such as hose-in-hose and carnation types, are double. Some are “polymerous,” meaning they have additional petals and sepals (830). Daylilies range in size from small to over six feet tall! Some daylilies immediately put up two sets of scapes and rebloom, while others rest for a few weeks before doing so. Many have a light fragrance. Last but not least, hybridizers changed the chromosomes from the diploid (22 chromosomes) to the tetraploid (44 chromosomes). The H. fulva is a triploid with 33 chromosomes, whereas the H. fulva is a diploid. Tetraploid plants, or “Tets,” have bigger blooms, thicker scapes, and stronger-looking plants overall. Due to the expense of transforming the superior diploid plants into tetraploids, they tend to be more expensive and have given the hybridizer access to more genes. The following images demonstrate a few of the numerous developments in daylily hybridization:
Asian dishes like Moo Shu Pork employ daylilies because they are edible. After tasting the blooms, I discovered that they can range from mild to extremely spicy. Additionally edible are young leaves and roots. Because of this, deer and voles may easily prey on them. Aphids, spider mites, thrips, and slugs are among more pests. Daylilies occasionally get “spring sickness, but they normally bounce back. Otherwise, they are disease-free in our growing zone with its harsh winters. They are affected by a fatal rust in zones 9, 10, and 11. It is advisable to confine daylilies you purchase from those regions over the winter until the cold has destroyed the sickness. Daylilies are deadly to cats, by the way, but I’ve never heard of a cat being drawn to them.
The favorite plant of many gardeners is the daylily. They are dependable perennials, have numerous, vibrant blooms, and are generally pest-free—the exception being deer. Daylilies may grow in either full sun or light shade and can withstand drought, flooding, heat stress, and most soil types.
