The basic rule of thumb is to dig the hole 2-3 times wider than the original pot but just as deep when planting a potted perennial, including daylilies. The hole should be 12 to 18 inches broad and 6 inches deep if your daylily is in a 6 by 6 inch container.
Not separating and spreading the root mass when the daylily is removed from its pot is a typical mistake committed when replanting container-grown daylilies. The daylily’s roots will be encouraged to grow out from their native soil into the surrounding garden soil by loosening up the rootball and spreading it apart. Perennial plants planted in containers are commonly grown in “soilless” potting soils made of peat moss, decomposed bark, and perlite. These mixtures are completely unrelated to the garden soil that you will be replanting your daylilies in. It’s crucial to refrain from planting these daylilies straight into your existing garden soil without first prepping it. (Refer to Soil Preparation above.)
Bare root daylilies require a little more labor to plant, but the extra work is worthwhile. Make a hole that is 12 to 18 inches wide and 12 to 24 inches deep. Create a mound of dirt in the hole’s bottom. Place the bare root daylily on top of the mound so that when the hole is filled with dirt, the crown will be approximately an inch below the soil line. The roots should be dispersed all around the soil mound. Refill the soil around the plant and compact it. Avoid having any air pockets. After planting, give the area plenty of water.
If you live in a region of the country that is extremely warm, you should water your newly planted daylilies more frequently than once per week. AVOID watering daily. Daylilies that have just been planted need to be encouraged to sprout new roots, which they will do in quest of moisture. Daylilies that have just been planted hardly ever rot, although they can become stressed if they are overwatered in hot weather. When in doubt, avoid killing your daylilies gently!
Are daylilies anchored deeply?
Even though they are frequently referred to as daylily bulbs and even sold as such, they are not real bulbs. Why is a daylily plant not a bulb? Let’s explain.
An underground root system that extends from the daylily’s crown and descends into the soil gives the plant a permanent growth habit and anchors it to a secure location in the ground. Because daylilies have underground storage organs that can store nutrients, they are somewhat drought tolerant and can release the stored food when it is needed. Because of their robust root systems, gardeners will occasionally plant them in large numbers on slopes, retaining walls, and steep embankments. This can help to prevent soil erosion.
Daylily plants produce significantly more photosynthesis in the summer. Plants store this energy and use it when the weather is unfavorable. The fibrous roots of daylilies release their stored energy during harsh winter conditions, such as during winter snow or cold, gloomy days with little sunlight.
A daylily needs a crown or a portion of a crown to grow either roots or foliage; it cannot grow from just its roots. Having said that, daylilies are not referred to as having daylily tubers even though occasionally you will detect a thickening along or at the end of the daylily roots that resembles an oblong little tuber and may even be comparable to a small dahlia tuber.
When daylilies form short, shallow roots with tubers right on the ends, it is likely that they have not received adequate watering. This is why some daylilies have thickening or small tubers on the end of the roots. There is no secret to creating tubers on the ends of daylily roots; all you need to do is water them shallowly. This does not occur if you water your daylilies deeply, as daylilies should be watered.
Spring bulbs, such as tulips, daffodils, hippeastrums, alliums, grape hyacinths, and garlic, are the best examples of bulbs. These bulbs are spherical, come in a range of sizes, from large to little, and have a covering that resembles paper.
When it comes to planting daylilies, you need to keep in mind that they don’t have ‘true bulb’ structures like other lilies do. Daylilies also have very long, extensive roots, therefore the planting depth needs to be at least one foot deep for the roots to grow into. You should take these factors into account in order to maximize the benefits of these plants. The greatest way to enhance a strong, deep daylily root system is with proper care and maintenance, including deep watering.
Do you still have questions regarding whether daylilies have roots or bulbs? You can clearly see that daylilies have roots rather than a bulb in the picture of one of our daylily plants that is about to be shipped to a customer in Western Australia.
To ensure that you get to experience all the advantages of these lovely blooms known as daylilies, be sure to grow, plant, and tend to your daylilies as tuberous roots rather than daylily bulbs.
Give Daylilies a Sunny Spot
For a decent bloom show, daylilies, which are high energy plants, require at least six hours of direct sunlight daily. The plants will have lovely foliage but fewer flowers when grown in partial shade. Nevertheless, cultivars with dark blooms retain their color better in hot climates when they receive some afternoon shade.
If you’re planning to plant daylilies in a specific location of your yard, think about pairing them with daffodils. Both plants are robust and capable of thriving in the same soil. While the daylilies are still dormant in the early spring, the bulbs will bloom. The daylilies will then bloom, covering the dying daffodil leaves with lush greenery. Anytime before the ground freezes in the fall is a good time to put daffodil bulbs.
Mulch to Control Weeds and Conserve Moisture
Although daylilies can withstand drought, they prefer to grow in soil that is consistently moist throughout the growth season. In actuality, daylilies are content to grow next to a pond or temporary river. They also contribute to a reduction in soil erosion thanks to their shallow, dense root systems.
Daylilies can be a vibrant, low-maintenance option if your yard has any places that are hilly or otherwise challenging to maintain. Plant them alongside fences, stream banks, drainage ditches, and even urban hell strips. The plants thrive in containers and don’t mind rocky or compacted soil.
Loosen the soil and get rid of any grass or weeds before you plant a big bed of daylilies. Apply two layers of mulch after planting to help preserve moisture and control weeds. In arid places, mulch is extremely helpful. Plant daylilies 12–18 inches apart on centers if you want them to grow as a ground cover. For the first few years, keep the area weed-free. The plants should be able to outcompete the majority of weeds after they have filled in.
Don’t Hesitate to Move and Divide
Daylilies are simple to transfer and divide. Their large, fleshy roots provide them with a natural buffer as they adapt to their new environment by storing moisture and energy. Although daylilies can be divided at practically any time during the growing season in northern regions, early spring or early fall are the optimum times to do it.
There is no set time when daylily cultivars should be divided because some are more vigorous than others. It’s probably time if you’re getting fewer flowers and you can’t see any earth between the plants.
You can dig up the entire plant and then break it into smaller pieces, or you can use a pointed spade to chop away pieces of the main clump of daylilies. You can trim the foliage back to around 5 inches for better handling. When replanting, place the plant’s crown (where the roots and stem meet) no deeper than an inch into the ground.
Keep Daylilies Looking Their Best
A daylily flower only blooms once. Snap off the spent blooms to maintain the plants looking their best, being careful not to disrupt neighboring buds. You’ll be astonished at how much nicer the plants appear after doing this, which only takes a few seconds.
Cut a scape (stem) back to the ground when all of the buds on it have completed blooming. By doing this, you may maintain the plant tidy and stop it from investing energy into making seeds. Another flush of blooms is also encouraged in reblooming varieties.
After flowering, daylily foliage occasionally becomes limp or starts to turn yellow. If this occurs, trimming the foliage will encourage a new flush of leaves. Another choice is to move the plant such that the foliage of nearby plants partially conceals its leaves.
Winter is when most daylilies die back to the ground. To make room for new growth in the spring, rake or pull away the fallen leaves. Some cultivars are “evergreen,” meaning that they may keep their foliage all year long in warm areas. Simply trim back any ragged foliage in the spring.

Is it difficult to dig up daylilies?
Weedy daylilies can be highly destructive in the areas around your house or in your own personal garden. Since they can be fairly challenging to get rid of, it’s critical to take action right away once you discover them.
What sort of roots have daylilies?
Daylily plants have a variety of root systems, ranging from the typical fleshy form to one that is practically fibrous. Some daylilies have rhizomes or underground stems that spread across the soil as their root systems. Daylilies thrive in direct sunlight.
How long do daylilies live?
Daylilies are hardy plants that can live for many years. To ensure that their roots have enough room to expand, it is advised to divide them every three to six years.
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.
Daylilies can be moved when?
The greatest time to transplant daylilies is in the spring, when the shoots are just starting to appear, regardless of climate. Newly divided and transplanted plants benefit from cooler temperatures and light spring rains at this time as they begin to recuperate from transplant shock. Transplanting sooner rather than later enhances the likelihood that the plants will be able to recuperate sufficiently to bloom later in the season, however exact timing is not necessary.
Daylilies can be transplanted in the fall in the South (USDA growth zones 8 and higher). Wait till the summer heatwaves have passed at the end of September.
Do day lilies spread quickly?
Daylilies are the common term for hemerocallis plants; they are not real lilies. “Ditch lily” is another common name for the original hemerocallis fulva plants that were introduced to America in the 1790s. These plants grew quickly and produced a lot of colonizing 12-inch roots, which allowed them to leave the garden and naturally colonize any area, frequently filling the ditches next to roads. The hemerocallis fulva in question has been classified as an invasive species.
Online, in garden centers, or at nurseries acquired hybrid daylilies are all clump-forming, seed-setting plants that won’t spread invasively. The majority of daylilies produced in gardens won’t spread quickly. You can plant daylilies with confidence if your friend agrees to share some with you from their garden and the blossoms are any color other than orange. The majority of orange blooming daylilies are also risk-free, but if you do not know its name, acquire a ruling before putting it in your garden. The invasive hemerocallis fulva is depicted in the orange daylily above.
Daylilies are referred to as “the perfect perennial” by the American Hemerocallis Society for the following reasons:
- Daylilies bloom in a variety of hues and shapes.
- Daylilies grow well in a variety of environments and temperatures.
- Daylilies grow nicely in a variety of planting situations.
- Once established, daylilies are tolerant of drought, but they can also withstand heavy rain.
- Pests and disease rarely affect daylilies.
- Different types of daylilies bloom from late spring to autumn.
Daylilies flourish in an incredible variety of climates and conditions, with minimal care, from winter in Wisconsin to summer in Florida.
