What 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.
I live in the deep South, can I grow daylilies?
Yes, but you must select kinds that are either evergreen or semi-evergreen. In order to go dormant, dormant kinds prefer a cold winter season, and if they don’t get one, their health will deteriorate over time. (On our website, daylilies can be sorted based on the type of foliage.)
Will My Daylilies Bloom the First Year?
Although the plants we supply are flowering size, whether they blossom during the first growing season is mostly dependent on when you receive them. They are more likely to bloom if you grow them earlier in the season. (Of course, you have to wait until the majority of the risks of freezing have passed, so some of you can’t plant as early as you’d want.) In general, you should have a decent probability of flowering the first year if you can plant by early to mid April. Don’t count on daylilies planted later to bloom; it’s not a guarantee. In a similar vein, daylilies planted sufficiently early in the season may fail to bloom for no special reason other than the fact that they are living things and will therefore carry out their natural course of action.
What does dormant, semi-evergreen and evergreen mean?
This alludes to the vegetation. Daylilies that are dormant want a cold winter season during which they can do so (the foliage dies back to the ground). Semi-evergreen daylilies are in between, not fully covered in foliage but not completely dormant either. Evergreen daylilies attempt to grow foliage throughout the entire year. The sort of foliage doesn’t really matter if you live in a region with harsh winters because it will all freeze to the ground.
When is the best time of year to plant daylilies?
Although it’s best to plant in the spring and fall, many gardeners can do it successfully all summer long. (At our Tennessee nursery, we plant from March through October.)
Do I need to divide my daylilies?
Only if you discover your daylilies aren’t blooming as well as they once did will you truly need to divide them. While some types may require division every three to five years, others tend to thrive for much longer.
What kind of fertilizer should I use? And when should I fertilize?
Although daylilies aren’t very fussy, we advise using a premium, nitrogen-rich fertilizer in the spring and possibly once more in the fall.
What is rebloom?
“Rebloom refers to a daylily variety’s propensity to bloom more than once per year. The subsequent bloom cycles may occur immediately after the primary bloom cycle or they may occur weeks or months later. Several things to consider while reblooming
Due of their extended growing season, Southern growers will have a lot more chances to see rebloom than Northern producers.
Expect the rebloom to be less abundant than the initial bloom; this is frequently the case.
There aren’t good rebloomers in every color and style of daylily, so you will really limit your choices if just get rebloomers. It’s a nice trait if you can get it, but we typically recommend you choose the varieties that most catch your eye, regardless of whether they are rebloomers or not.
My daylilies aren’t blooming as well as they used to, what might cause that?
Your daylilies might require division. While some types require division every three to five years, others seem to thrive for much longer.
What does diploid and tetraploid mean?
Tetraploids (tets) have 44 chromosomes, compared to diploids (dips), which have 22. Tetraploids could appear “huskier, with bigger blooms and stalks,” although it isn’t always clear from a quick glance. Daylilies can only be crossed between diploids and tetraploids, therefore this is mostly just a problem if you want to hybridize them (cross them to make seeds).
Do daylily colors look different in different areas of the country?
Sometimes, although it’s difficult to determine why there might be a difference. The variances in some pink types, where the hue might change from peach to pink in different locations, are what we hear about the most frequently.
Is it too late to plant (this spring)?
“According to what you mean When you mean “If you want to plant daylilies this summer and have flowers, you must do so before they start sprouting bloom scapes (in our area, we would want to plant by the end of April or so). When you mean “If you’re wondering if it’s still possible to grow daylilies, the answer is probably no. For years, we have sent plants all throughout the nation during the summer.”
Is it too late to plant (this fall)?
Generally speaking, we advise planting daylilies three to four weeks before the first frost. You can plant later if you can add mulch after you’ve already planted.
I live in an area with severe winters, can I grow daylilies?
Yes, most daylilies thrive in cold climates, especially if there is a steady layer of snow cover (which acts as insulation). Some of the most difficult regions to grow are those with harsh winters but minimal snow cover or those with significant springtime temperature fluctuations (like here in Tennessee). Every now and again, we learn of a variety that doesn’t seem to be consistently hardy, in which case we stop selling it.
What is the duration of the daylily bloom?
Daylilies can be reproduced either from seed or as bare roots. The highest potential for success for the growing season is provided by the fact that our daylilies are sold as bare root perennials. Although it is feasible to grow daylilies from seed, hybridizers who want to produce new daylily types usually choose this route. While daylilies propagated from split roots will start flowering the same year they are planted, daylilies produced from seed will take two to three years to produce blossoms.
A decent setting is essential for your perennials to thrive.
Fortunately, daylilies are quite simple to plant. In order to prevent root rot, these plants require well-drained soil and at least six hours of direct sunlight per day. Mix & combine your daylilies to create the ideal look as you choose where to plant! Use tall types as focal points in the garden or use dwarf versions to fill in gaps under trees and in borders. Think about daylily bloom period as well. You can avoid having any “blank spaces” in your landscaping throughout the bloom season by combining types with earlier and later bloom periods.
It’s not particularly difficult to plant daylilies once you’ve selected your site. With a hoe, shovel, or claw tool, loosen the soil and include compost for nutrients and drainage. Before planting, soak your daylily’s bare roots in clean water for a couple of hours. The daylilies should then be planted such that the crown—where the tops of the roots and the leaves meet—is at ground level. Prepare to enjoy a season of beautiful blossoms by providing your plants with plenty of water.
How long do daylilies take to establish themselves?
The easiest to maintain perennial flowering plant is the daylily. The plants have rapid growth and a long lifespan. They can grow in practically any type of soil, in full sun or partial shade, and are rarely bothered by disease or insect pests. Although daylilies are renowned for their hardiness, their vibrant and many blossoms are equally stunning. With new blossoms emerging every day, blooming begins in the middle of summer and lasts through the beginning of autumn.
Plan for Success
Sun and Shade: Daylilies grow best in broad sunlight. Even in partial shade, the plants can thrive, though they could yield fewer flowers.
Zones 4-9. Hardiness zones are where most daylilies can flourish. Uncertain of your growing zone? Look at this USDA zone map.
Daylilies should be planted bareroot in the early spring while they are still dormant. You can plant daylilies in pots at any point during the growth season.
How to Plant Daylilies
To a depth of twelve, loosen the ground. Compost and general-purpose granular fertilizer should be combined (if desired).
Place the daylily in the hole with its crown—where the roots and stem meet—one inch below the soil line.
Where to Plant Daylilies
Continual Gardens Daylilies give flower beds and borders color in the middle of summer. They flower at the same time as Shasta daisies, bee balm, and garden phlox, which are high summer bloomers. It’s simple to pick a height, bloom time, and color combination that work for your garden from the thousands of types available.
Nature Reserves Despite the fact that daylilies are not native to a region, their flowers and foliage complement ornamental grasses, asters, echinacea, rudbeckia, and other plants with an unstructured growth pattern and the strength to survive on their own.
Grassy Slopes Daylilies can be an attractive, low-maintenance option for sloped or otherwise challenging-to-mow lawn areas. Their extensive root network prevents soil erosion and can suffocate the majority of weeds. Daffodils are best paired with daylilies. In late April, the daylily foliage emerges and covers the dying back daffodil foliage.
Wet Regions Daylilies can withstand dry conditions as well as wet feet. They work well in rain gardens and are ideal for planting next to ponds or streams.
Building Blocks and Fence Lines The use of daylilies to create a low-maintenance border along a fence, by a walkway or driveway, or up against an outbuilding is highly recommended. They’ll ease the burden of pruning and mowing by softerening sharp lines.
Containers Daylilies do well in pots, especially some of the dwarf types. The luxuriant foliage serves as an excellent backdrop for other flowers even when they are not in bloom.
What to Expect
Daylilies don’t care much about the soil and can grow in conditions that would be too damp or dry for most other perennials. Having said that, good, well-drained soil is ideal for growing daylilies.
Daylilies need watering in dry weather throughout their initial growing season. They will establish themselves more swiftly as a result. Water sparingly but thoroughly, ensuring that the water reaches the root zone. Mulching will help keep the soil moist and lessen weed competition around newly planted daylilies.
Daylilies need a year or two to establish themselves and find their footing, like the majority of perennials. They will bloom consistently after that for many years.
How to Care for Daylilies
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. Cut the scapes down to the ground once they have finished blooming to maintain the plants’ clean appearance and stop them from investing energy in seed formation. Additionally, this might help the plant to grow more flower spikes.
Although certain species of daylilies maintain their green color far into the winter, the foliage often starts to turn yellow in late fall. Late fall or early spring are good times to remove spent leaves. Waiting until spring will make it simple to remove.
Daylilies benefit from an annual spring application of granular all-purpose fertilizer, depending on the soil’s fertility (follow package directions). When you remove the foliage from the previous year, scatter the fertilizer all around the base of the plant.
Daylilies benefit from having bark, leaves, or other organic materials mulched around them. It makes weed management simple and maintains soil moisture.
Daylilies can flourish for many years without any care, although dividing the plants around every five years will increase flower production. After the plants have stopped blooming in the late summer, this is a work to be done. The entire plant should be dug out and laid out on a tarp. To make the clump easier to handle, cut or pull it apart. Use scissors to cut the leaves back to 5 or 6 inches before transplanting.
Why didn’t this year’s daylilies bloom for me?
Growers should first confirm that they have provided the growing conditions necessary for the plant to survive if their daylily isn’t blooming. Non-flowering in daylilies might be an indication of a few problems. Most frequently, your plant might not be getting enough sunlight in the garden.
How should daylilies that don’t blossom be handled?
This is a simple solution if your daylily stopped flowering because it was overcrowded. To ensure that your daylilies bloom continuously, it is advised that you prune their roots every two to three years.
How can daylilies be made to bloom?
Due to their beauty and ease of cultivation, daylilies (Hemerocallis) have long been a favorite perennial plant in gardens and retail settings.
Since daylilies naturally bloom towards the middle to end of summer, it might be difficult for businesses to have them in flower when retail traffic is at its highest. Particularly with more recent kinds like “Primal Scream” and “Ruby Spider,” which have large 8- to 9-inch petals, their vibrant flowers heighten their allure. The potential for sales for stores is substantially increased when plants are in bloom while more people are shopping.
Over the past few years, Walters Gardens in west Michigan has been conducting Hemerocallis forcing trials to assist their grower-retailer clients develop methods for producing flowering daylilies for spring sales. In these studies, a variety of cultivars were used, and the time to bloom and plant quality characteristics were assessed.
This year, Walters Gardens concentrated on testing daylilies in two climates: chilly (60 F) with natural day lengths and warm (75 F) with 16-hour days utilizing day extension lighting. Daylilies that were started in early January and went dormant and vernalized were used.
The daylilies were introduced into each of the testing environments on January 9, 2012. Each variety’s time to attain visible flower scapes (visible buds) and grow open blooms was noted. Table 1 presents the outcomes.
In this experiment, day duration had no bearing on flowering; plants blossomed during both natural and long days. Hemerocallis are categorized as day neutral plants, therefore this is most likely why. When they are grown in high light intensities, they do flower more consistently and produce more flowers per plant.
Each daylily variety had a different flowering time. The ability to offer adequate cooling on warm sunny days and the outside weather conditions had a significant impact on the planned 24 hour temperature averages.
Some farmers look for daylily cultivars with long blooming times and reblooming traits to increase their marketing and sales windows. To increase the sales window, growers might also attempt forcing early, medium, and late season types. As each new variety blooms, having a diversity of bloom times provides a new aesthetic for the bench and new potential for impulse purchases.
Seasonality is a further consideration for producers. If daylilies are planted later in the spring rather than in the middle of winter, as in this trial, they will bloom much more quickly. My prior observations have shown that forcing daylilies in March or April as opposed to January or February results in a two-week reduction in the time it takes for them to flower.
Daylilies don’t necessarily need to be grown in conditions with high temperatures for them to bloom. When they are grown in cool temperatures, they will also blossom, however it will take a little longer. For most cultivars in these trials, the time to flower increased by eight to fifteen days when the temperature was lowered from 75 F to 60 F. For optimal results, I advise growing daylilies in areas with strong light intensities at 65 F.
Hemerocallis are simple to grow, and the crop’s uniformity, performance, and marketability will increase by following the production guidelines below and incorporating the findings from the forcing trials mentioned above. The most common way to start daylilies is using bare root divisions. The majority of growers use 1-gallon containers filled with a well-drained commercial growth mix to plant bare root starting materials of grade #1. The crown should be planted between a half-inch and an inch beneath the media surface. After potting them, thoroughly water them before setting them in the production area.
Generally speaking, fertilization is not required in the first few weeks of production. Daylilies have a moderate appetite after they are established and actively developing. Liquid fertilizer applications can offer fertility by applying 75 to 125 ppm with each irrigation or 200 to 250 ppm once or twice per week.
Many gardeners use controlled release fertilizers to give nutrients by either topdressing with the medium suggested rate or incorporating the low to medium recommended rate. The media’s pH level needs to stay between 6.2 and 6.7. Avoid overfertilizing because it could cause soft growth.
Transplant #1 grade bare root daylilies eight to fifteen weeks prior to the targeted sales window in order to generate flowering plants for spring sales. To estimate the length of time till flowering for each individual variety, consult Table 1. The blooming classification can be used to estimate the time to flower for cultivars not included in this table. For instance, when growing daylilies in the late winter with a 24 hour average temperature of 65 F, early blooming cultivars will flower in around eight to ten weeks, midway cultivars in about eleven to thirteen weeks, and late season cultivars in about fourteen to sixteen weeks. Daylilies will take roughly six to ten weeks to complete if they are started in the spring for sales in the middle to end of the summer.
Using the techniques outlined above and shown in the experiment by Walters Gardens, Inc., growers wishing to boost their early season Hemerocallis sales can do it quickly and affordably.

At retail, a daylily in bloom is very appealing to customers. Understanding how to plan blooms for peak retail traffic presents a problem for growers.
