The height of a daylily clump can range from six inches to five feet. Space bare roots about three feet apart since they can grow to a span of two to four feet wide (or for a more dramatic show in the early years, space about 18 inches apart).
Are daylilies self-propagating?
- Zones 3–9 are considered to be hardy.
- Daylilies can grow in nearly any type of soil, but adding compost can enhance drainage and nutrition and help them bloom more effectively.
- Sunlight: full (6 hours per day).
- Drought-resistant, but flowers better with one inch of water each week.
- Give daylilies plenty of room because they dislike competition and quickly grow to cover enormous regions.
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 soil 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.
Where should a daylily be planted for optimum results?
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.

How many daylilies can you plant in a single planting?
I had a variety of roles as a founding worker at Gardener’s Supply over the years. I currently run my own business, which is called Johnnie Brook Creative. A huge vegetable garden, a seasonal greenhouse, a cutting garden, perennial gardens, a rock garden, a shade garden, berry plantings, numerous container plants, and a meadow garden are among the gardens surrounding my Richmond, Vermont, home. The garden is the only place I would rather be. Check out this Garden Gate magazine video interview from January 2021 if you’re interested in learning more.
The daylily is the only perennial that can be considered a “guaranteed thing.” They do well in zones 3 to 9 (from Minnesota to Florida), can survive a wide range of soil types, are unaffected by diseases or pests, and consistently bloom for years with hardly any care. Hemerocallis, the daylily’s botanical name, literally translates to “beauty for a day,” and in fact, the majority of daylily flowers open in the morning and wither by dusk. The plant blooms for several weeks because each flower stem, also known as a scape, often bears at least a dozen flower buds.
Daylilies, unlike the majority of perennials, can be used in a variety of ways in the garden and landscape. The shorter, more compact kinds grow nicely when planted straight into perennial borders, where their blossoms provide the landscape a much-needed lift in the middle of summer. Daylilies are best planted in groups of three or five for landscapes, especially when combined with tiny shrubs and decorative grasses. Daylilies make the ideal plant for mass plantings along fences or walkways since they create a weed-free display that is thick and attractive.
How soon will daylilies grow?
A hardy perennial, daylilies can withstand prolonged neglect and yet add vibrant splashes of color to the landscape. I am aware because I have abused daylilies. It’s simple to forget that they can flourish with some assistance because they thrive in poor soil, severe weather, inadequate light, and bone-dry circumstances. The plants will thrive with only minimal maintenance, and you’ll soon discover that your garden needs more. Given how simple it is to reproduce daylilies, this is hardly a problem.
Daylily plants come in a variety of sizes, from small, feathery clusters to big, fans of green leaves, and the flowers offer a rainbow spectrum of colors that bloom over a lengthy period of time. Because of these variations in color and size, I’ve discovered that sometimes when I plant, I do so with an artistic goal in mind, but as the plants grow, I find myself wanting to move them around and grow more of the ones I particularly enjoy. A blessing in those circumstances is simple propagation.
There are just two main methods for growing daylilies. By seed is first. The flowers dry after flowering and pollination, at which point a tiny, green seed pod forms at the base. The seed pod will develop over the course of a few months, and as it reaches maturity, it will turn brown. Eventually, the brown pods will break open. There will be shiny black seeds inside. These immature seeds should be sown in the fall for natural winter cold or they should be stored in the refrigerator in a plastic bag for approximately a month in order for them to germinate. They are prepared to seed outside in the spring after this cooling off phase.
It’s a gamble to collect and plant daylily seeds in your garden. You are probably growing hybrid daylilies. Because they are a cross between different types, they won’t grow true to the parent plant when produced from seed. You cannot distinguish which flower fertilized another if you have different daylilies in your bed. Pollination from various hybrid parents or hybrid cultivars will produce a seed that will eventually develop into an unidentified plant.
A seed may need three years to sprout and develop into a flowering plant. Be prepared for a surprise when the plant sprouts its first bloom after all that time. There is no way to predict in advance what color or size it will be, but given the wealth of advantages daylilies provide, it will undoubtedly be a pleasant surprise.
Remove the seed pods if you don’t want to save the seeds. Usually, plants that produce seeds the next year have fewer blossoms. There is no justification to purposefully limit future blossoms as one of the main reasons daylilies are grown is for their flowers.
Division is the second method of daylily propagation. When you want your plant to have the same size and color as the parent, dividing large clumps of daylilies is the ideal technique of propagation. In addition, flowers will grow more quickly. Every three to four years, each plant forms a clump that is prepared for division. You’re doing yourself and the plant a favor by routinely dividing because undivided plants will start to produce fewer flowers.
You can divide daylilies in the spring or the fall. After being divided in the spring, plants develop swiftly, although they rarely blossom the first year. I favor propagating in the fall primarily for that reason. Plants propagated in the fall usually always blossom the following season. The best time to divide and transplant the divisions is after the plant has flowered, but at least six weeks before the ground freezes.
Start by completely digging up the plant. Push your spade as far as you can in a circle around the plant, starting approximately six to eight inches away. With the spade, lift the plant while attempting to preserve the rootball. While it shouldn’t be too difficult, larger plants might have roots that extend beyond the hole and could potentially be torn as a result.
To reveal the roots, brush or wash away the soil that is covering them. The roots of many daylilies are swollen and tuberous. The plant stores its food and water here, allowing the divisions to thrive after transplanting. The transplant has a better likelihood of success the more roots there are in the division.
You can see how the fans come together at the roots to produce different and unique parts. These sections can be separated from one another. It is simplest for me to start by lightly shaking the plant and observing where it naturally starts to split. I next carefully divide the plant into two parts. Each of those divisions can frequently be further broken down into two or three other divisions.
When pulling gently, bigger plants and clusters might not separate. It could be necessary to split the clump by inserting two garden forks back to back in the center of it. Garden forks lessen root damage compared to using two spades, which causes greater harm. The divisions can typically be further separated by hand once they are smaller.
Divisions ought to have three or four sturdy roots attached fans. These will take root more quickly, form sturdy clumps, and bloom after a year. You can even cut it into smaller pieces so that each fan has just five or six thin leaves. These individual fans can be moved without issue, but it might take them a few seasons to get big enough to start blooming.
There are some enormous, mature clumps that may have roots that are so thick in the middle that they resemble a solid mass. It might be necessary to use a sharp shovel or garden knife to split these clumps apart. Try to cut so that the identity of the individual fans is preserved.
To prevent the roots from drying up, the divisions should be transferred as soon as they are dug up. Cut the leaves on each division so that just five to six inches are left above the crown. This lessens stress and water loss. The area at the junction of the leaves and roots is known as the crown and is often cream in color. Put the plant in the hole with the crown a little more than an inch beneath the surface.
Daylilies thrive in broad sunlight and moist, organically-rich soil. If you can add organic stuff to the transplant area in advance, do so. A high phosphorus fertilizer addition will aid in promoting root growth. The dirt in the hole for each plant should at the very least have a handful of compost and fertilizer added to it if you’re transplanting divisions amid other, established plants, as I frequently do. Fill the hole and compact the earth around the roots.
Water the area well after the divisions have been planted. Till the ground freezes, keep the soil moist. To control the soil’s temperature and moisture content, add a few inches of mulch. Mulch also helps the plants look more attractive and lessens weed growth.
For some daylily varieties, there is a third way of propagation available. Some daylilies’ stems, or scapes, may support tiny plants. If kept on the plant for a long enough period of time, this tiny plant will develop leaves, a crown, and even roots. Proliferations are the name given to these little clones of the original daylily. Proliferations can either be transplanted or potted up. Both above and below the proliferation, cut the scape. The crown can be dipped in rooting hormone to aid start the growth of roots if they haven’t already started. Since none of the daylily kinds I cultivate produce proliferations, I am unable to speak from personal experience with this approach.
Daylilies eventually grow into thick mats of vegetation. You can keep the plants under control and looking their best by dividing them. A excellent approach to spread their wonder to new locations is through reproduction. Remember that many of your friends who garden might be interested in some of your excess divisions.
