Daylilies can be divided into groups based on their height, flower form (trumpet, double, ruffled, or recurved), blossom color, and bloom duration. Planting a selection of lilies with early, mid, and late flowering inclinations is a wonderful way to ensure that you have daylilies throughout the summer.
The best conditions for daylilies to grow are full light (six or more hours each day) and moist, well-drained soil. Before planting, add compost to the soil.
Daylilies should be planted in the South in the fall or early spring when it’s still cool outside, and in the North in the spring.
Until you’re ready to plant them, keep your roots in a cool location. Soak the bare root in water for a couple of hours before to planting.
At the bottom of the hole, make a mound of loose earth in the shape of a cone to hold the root. Spread the root system of the daylily over the mound, and then cover it with loose soil. Daylilies need to be spaced between 18 and 24 inches.
The junction of the leaves and the summits of the roots is known as the crown. Add about an inch of loose dirt over the crown. Don’t push down the earth too hard; just gently tighten it up around the roots. Mulch with pine straw or bark.
If it’s dry out, water your daylilies every day for a week or two after planting. While daylilies don’t actually require much overwintering care because they are so hardy, a covering of mulch may help them develop a stronger root structure.
Can daylilies be rooted in water?
The daylily is practically disease- and pest-free, easy to grow, and resilient to drought, shade, and poor soil, making it the ideal perennial. Discover how to cultivate daylilies and quickly propagate them for extra plants!
These plants, which are originally from Asia, have adapted so successfully that many of us consider them to be locals. Imagine how thrilling it would have been for a 16th-century traveller to tour the Orient and discover these beautiful flora! Daylilies were welcomed into European gardens by gardeners, and they traveled to the New World with the first colonists.
Daylilies have a long tradition of being used in both gardens and kitchens. The delicate foliage was used as a spring green, the buds and blooms were added to soups and consumed raw, and the swollen parts of the root were cooked and consumed. When cooked in stews, soups, or sauces, all sections have a mild peppery flavor and serve as a thickening factor.
Considering that each blossom only lasts for one day, their botanical name Hemerocallis means “beauty for a day.” Daylilies grow from fleshy roots instead of genuine lilies’ bulbs, and their flowers appear on scapes that are leafless and rise above the leaves. One of the 12–15 buds on each scape opens every two days. With 4 to 6 scapes on an adult plant, there is a lengthy bloom time. Some plants can grow up to six feet tall, measured by the length of the scape!
Divide the daylily clumps before the autumnal equinox in late summer or early fall after flowering (late July to mid-September) in order to multiply them. Before winter, the plants need at least six weeks to reestablish themselves.
Even though many gardening guides advise using two garden forks to cut or push the roots apart, I’ve had good luck by briefly soaking the roots in a pail of water until the majority of the soil is gone. After that, breaking up the clumps is considerably simpler (and you do not damage the plant). Dig up the whole cluster. Check the location of the crown once the earth has been removed. Break it up into larger clumps beginning at the edge (two, three, or no more than four). Reduce the length of the leaves by about a third to a half. Replant. If you want to hasten growth, you can add a fertilizer heavy in phosphorus.
Daylilies thrive in full sun and a location with healthy, well-drained soil, though they will endure in less-than-ideal situations. One inch should be buried beneath the plant’s crown, which is where the leaves and roots converge. Water and mulch a daylily that has just been planted to keep it moist. Daylilies are unaffected by the red lily-leaf insect, which has ravaged Asiatic and Oriental lilies.
There are countless lovely daylilies to pick from. To have daylilies bloom from late spring into fall, combine early, mid-season, late flowering kinds, and repeat bloomers.
Did you know: Despite their name, daylilies are not “real” lilies (from the genus Lilium). If you’re interested in learning how to grow Asiatic and Oriental lilies, visit our Lilies page.
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.
Before planting, should bare root daylilies be soaked?
Before planting your bare-root daylilies, it is advisable to soak their roots for a couple of hours in a bucket filled with a few inches of water.
Will distilled water help plants take root?
We worry about giving our plants the wrong kind of water in addition to over- and under-watering them. Does drinking tap water make leaves brown? You ought to test the rainwater. Possibly the water in your fish tank? Let’s quickly review our water options!
Distilled: Distilled water is essentially devoid of all life because everything has been boiled out of it. When the pure water turns into steam and is collected, you have your own distilled water. This implies that both the harmful minerals and contaminants like chemicals and heavy metals are eliminated. Particularly if the water originates from a source like farm runoff, trace quantities of pollutants may still be present. Those kinds of impurities shouldn’t be a problem if you’re distilling your own water from the tap. Therefore, while using distilled water to water your plants is possible, the beneficial minerals that support the plant’s health and growth have been eliminated.
The very greatest form of water you can offer your plants is rain or melted snow. Your plants will grow bigger and healthier with this water than with any other because it is rich in minerals that are essential for plant growth. Given that the same plants you grow in your home typically grow wild somewhere and receive water from rain, this is kind of a no-brainer!
Aquarium water is great, says the fish tank. Although it is still superior to rainwater, it is still quite good. It is a very light fertilizer because you are utilizing tap water, a water conditioner to eliminate impurities, and water that contains trace amounts of animal excrement. In our experience, it doesn’t smell when you water your fish tank, so you shouldn’t have to worry about that. However, occasionally individuals worry that it will smell unpleasant.
Spring: Remember how I said that the best thing you can give plants is rainwater? This is a close second, though. Like rainwater, it derives from a natural source, so there are no additional chemicals that would prevent your plants from growing as well as they could. I’m referring to pure, unfiltered spring water, not the bottled water that you can buy.
Purified water is distilled water with an additional step added, leaving it with nothing else except the well-known chemical composition of two hydrogen atoms and one oxygen atom. Indeed, water. I know it seems strange to imagine that the water that surrounds us contains things, but it does. Unless it’s been purified.
R/O Water: Reverse osmosis, often known as R/O, is a method for purifying water by removing minerals and pollutants such salts, chloramine, and heavy metals. Giving plants this is okay, and some people even prefer it because it doesn’t contain specific minerals that can interfere with fertilizers. The drawback of this is that the water is devoid of all nutrients, so it’s crucial to use a fertilizer that is properly balanced.
R/O Waste: Because it is waste water, which contains all of the chemicals and other things that are removed, this water is not fit for human consumption. This refers to the chloramine, salts, and heavy metals—all the undesirable substances that we remove but which plants dislike. There are also the beneficial minerals, however they are similarly concentrated to the chemicals.
If your water is hard and you use a water softener to treat it, you may want to hold off on giving it to your plants. This is done with salts, which are bad for plants and can actually slow down growth.
Salt or sugar: no. Simply said, don’t do this. It is a poor idea to add any of these to the water you will be giving your plants, and it will only make matters worse. You may have water that is too high in salt, which is unhealthy for your plants, if you see a white crust forming on top of your soil. Sugar can draw insects and promote the growth of mold, neither of which are desirable.

How to Propagate Daylilies
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. To divide and transplant the divisions, you should wait until 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. Dip the crown 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.
