Daylilies are the first perennial that a newbie should try, Mark Viette will say. And rightfully so. The third generation of his family to work with their development and breeding is Mark. He runs Viette Nurseries, a stunning retail garden center decorated with magnificent displays of daylilies and other perennials in the rolling hills of Fishersville, Virginia, with his parents, Andre and Claire.
Daylilies reach their full bloom in June. On stems that are between one and five feet tall, you’ll find blooms of all different colors. Although each flower only lasts for one day, plants often bloom repeatedly over the course of four to five weeks. While a small number of daylilies known as everbloomers flower almost the entire summer, rebloomers produce many performances each year. Here is Mark’s inside scoop on how to maximize the potential of these inexpensive beauties.
For the most blossoms, plant in full sun. Daylilies may grow in almost any well-drained soil, but for best results, amend the soil before planting with a lot of organic material, such as peat moss, chopped leaves, composted manure, and kitchen compost. Water thoroughly before mulching with 2 to 3 inches of pine straw or ground bark. Espoma Plant-tone 5-3-3, an organic fertilizer that delivers healthy soil bacteria, is fed to Mark’s plants in the spring and the fall.
Daylilies can they grow in Zone 6?
Daylilies are among the easiest and least fussy perennials to grow. They are quite understanding of gardening “mistakes” and are very tolerant of a wide range of circumstances. However, providing your daylilies with the ideal growing conditions really pays off. They will react appropriately.
Which Daylilies Can I Grow?
Most of you can grow any of the daylilies we sell, so it’s really not complicated. You may grow all the types if you reside in a region with a prolonged winter period, like we do in East Tennessee. Dormant types won’t work for you if you reside in a region without freezing temperatures during the winter; you must pick evergreen or semi-evergreen varieties instead.
When can I plant daylilies?
Daylilies grow best in the spring, but don’t plant them until the threat of a hard frost has passed. Another good time to plant is in the fall. Aim to complete your planting 4-6 weeks before the first hard frost. If you take the time to water and mulch your newly planted daylilies, you can plant earlier in the spring or later in the fall. As long as you give your newly planted daylilies plenty of water, you can plant daylilies in the summer in most places (here at our nursery, we plant continuously from March through October). Gardeners in the country’s hottest regions can frequently plant continuously through the winter, but they may wish to avoid planting during the sweltering summer months.
Shipments for spring should be delivered when the earth has thawed and the threat of a strong frost has subsided. Although you can plant later if you mulch the plants, fall shipments should arrive several weeks before it gets too cold.
Where can I plant daylilies?
Sun: Daylilies prefer full sun, but they will grow in partial shade as well. Make sure they receive at least 6 hours of direct sunlight each day as a general guideline. In the hottest part of the day, many kinds with darker colors will benefit from some partial shade.
Daylilies may grow in a broad variety of pHs and soil types, from light sand to dense clay. You can take measures to enhance your soil, particularly if it is primarily clay or sand. Compost, humus, peat moss, or sand can be added to clay soil to enhance it and to make it more friable. Compost, humus, or peat moss can be added to sandy soil to help boost water retention.
Daylilies prefer soil that drains properly. Making raised beds in problem locations is one technique to ensure proper drainage.
Other Plants: If at all possible, avoid planting daylilies close to shrubs or trees to prevent root competition for water and nutrients. In order to make up for what the other plants lose, be sure to give them more water and fertilizer if you can’t prevent it. A notable exception is the South, where daylilies thrive in the dappled shade of pine trees.
Work your soil in advance and, if you can, add organic material like compost or well-rotted manure to help your daylilies grow.
Will Daylilies Grow in a Container?
Yes, but you must make sure that the container is big enough, and you must maintain the plants well-watered (every day in the summer heat). You should use at least a 12-inch-diameter pot for smaller-stature plants (15–18-inch pots are preferable), which are often the ones with smaller blooms. Larger pots are required for larger kinds.
Your potted daylilies will need to be protected over the winter if you live in a zone 7 or colder. Our nursery’s zone 6/7 unheated cold frame is where we store our potted daylilies. Other methods for protection include bundling pots together and covering with straw, as well as placing them in a garage or crawl space. Daylilies will require greater care if your winters are particularly cold since they risk freezing their pots to death.
When can I divide my daylilies?
Any daylily clump with two or more plants (fans) can be divided, but you usually want to wait until the clump is big enough to be divided into at least two good-sized units with at least three fans apiece. They probably won’t bloom for one or two seasons if you divide them too thinly (like the plant on the left in the picture on the far right). Visit our YouTube website for further details and video tutorials on how to divide daylilies.
Spacing
Although daylily plants come in a variety of sizes, the following general recommendations should be followed:
- 16 to 24 little flowers and miniatures
- Flowers: 18 to 30 large
- 12 to 18 for a closer bed or boundary
Some types grow very quickly and eventually get crowded; the closer you plant them, the sooner this happens. You should divide your daylilies if you see a drop in blooming as a result of crowding.
How can I control weeds around my daylilies?
The best methods for managing weeds in daylilies include mulching and hand weeding. They don’t really care what kind of mulch it is. To find out what herbicides are available in your area to control grasses in daylilies, contact your local extension office or garden center.
What kind of fertilizer to use, and when?
When it comes to fertilizer, daylilies are tolerant. Each spring, before the daylilies start to blossom, we usually apply a premium, nitrogen-rich fertilizer. Additionally effective options are compost, liquid fertilizer, slow release fertilizer, and well-rotted manure. It’s crucial to use a mix that is heavy in nitrogen because daylilies adore nitrogen. A soil test is usually a smart idea, particularly if you suspect you have an uncommon soil situation.
When do daylilies flower?
Hemerocallis, sometimes known as daylilies, are not genuine lilies. Daylilies are perennial plants that develop from underground root systems rather than rhizomatous bulbs. The majority of daylilies have six sepals, and the majority of them have six vibrant stamens in the flower’s center. Due of their dense and durable foliage, daylilies can be distinguished from genuine lilies by their strap-shaped green leaves.
Hemerocallis, the daylily’s botanical name, literally means “beauty for a day.” The majority of daylilies do have flowers that only endure for one day, however these hardy bloomers produce multiple blossoms on each scape or stem. Sun-friendly daylilies are a popular choice for landscaping because of their lengthy blooming season, simple maintenance, and disease resistance, as well as a superb quality for filling in sparse sections of the garden! With numerous doubled, ruffled, and variegated variations, these well-liked perennials can now bloom in almost any shade and color imaginable. In order to find the ideal plant for your needs and space, daylilies come in a variety of sizes, including dwarf varieties, tall varieties, and everything in between.
How long before daylilies bloom? By combining early, mid, and late flowering kinds, you may extend the blooming period from May through September. Daylilies typically bloom in June or July. Some species bloom twice a year, once in the spring and once in the late fall. Whatever you’re looking for, there’s a daylily out there that you’ll adore, we’re certain of it!
In Zone 6, are lilies perennials?
You should be aware that Zone 6 has a medium-length growing season with a frost-free time that lasts from mid-May to late September if you reside there. Boston, Buffalo, New York, Chicago, Columbus, Ohio, Kansas City, Missouri, and Pittsburgh are among the American cities that fall inside this plant hardiness zone. Among the plants for Zone 6 that we advise are asters, astilbe, bee balm, canna, coneflowers, crocus, daffodils, delphiniums, glads, hibiscus, hostas, hyacinths, irises, lilies, peonies, phlox, salvia, sedum, tulips, and yarrow.
Remember that your Zone 6 garden likely contains a number of microclimates, each of which is best suited for particular plant species and varieties. Spend some time identifying any microclimates that may exist in your yard or garden, whether it be an open region of your backyard that receives constant sunlight, a shady area beneath a large tree, a hill covered with rocks, or a marsh. It won’t take long for you to develop a natural instinct for selecting the Zone 6 plants that will also thrive in the unique microclimates of your garden.

When do daylilies bloom and for how long?
Daylily (Hemerocallis) is a remarkable and beautiful addition to the garden and is frequently referred to as the “perfect perennial” due to its many attributes, including showy flowers, a wide variety of vibrant colors, drought tolerance, immunity to heat stress, ability to grow in most hardiness zones, and low maintenance needs.
- Depending on the kind and your region, daylilies may bloom from early spring till frost. Their blooming period is only 1 to 5 weeks long. Extra Early: From March or April in the South to May or June in the North, these daylilies are the first to bloom. Early: Three to five weeks before the midseason blooming mass, these daylilies blossom. Early Midseason: These daylilies bloom one to three weeks before the majority of cultivars reach their peak bloom. Midseason: From May in the South to July in the North, these daylilies bloom at the height of the daylily bloom. Late Midseason: 1-3 weeks following the height or peak of bloom in your garden, these daylilies bloom. Late: These daylilies bloom 4-6 weeks after the peak of the season, after the majority of them have done blooming. Very Late: In the South, these daylilies often bloom in the late summer or early October.
- Many plants are “reblooming.” These daylilies have many blooms in a single season. Some of them bloom in the spring (for instance, in May or June) and then again in the fall. Others have a series of bloom periods that happen one right after another over the course of several months.
To promote new buds and reblooming, prune off the old daylilies’ blooms as soon as they start to wilt.
These attractive Daylily varieties are appreciated for their capacity to bloom again. Enjoy!
How can you ensure that daylilies bloom all summer long?
To promote more blossoms, frequently deadhead daylilies. Every day, remove any spent blooms. After all blooms have vanished, cut the blooming stem back to the ground. Using sharp scissors or pruners is the ideal technique to deadhead daylilies because of their thick stems, as doing so risks snapping off any nearby blossoms.
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.
