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 labour 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!
Can you ever plant daylilies too deeply?
Daylilies are low-maintenance perennials that provide the garden months of blooming colour and texture.
Another name for daylilies is “hemerocallis.” They are herbaceous plants that have leafless stems or “scapes” on which the flower bloom develops and rich, lustrous green foliage. A single scape can support several flower blooms.
Daylilies can flourish in a variety of environments. This does not imply that they will flourish and perform admirably when treated poorly. Like most plants, daylilies appreciate attention and will flourish for you if you offer them some.
Daylilies require sunlight for at least half of the day in order to produce their flowers at their highest potential. Sun in the morning is preferred. The majority of cultivars can thrive in some shade. Red and dark-hued flowers will benefit from less exposure to the hot afternoon sun when they are in mild shade.
Daylilies may grow in a wide range of soil types. Spade any soil deeply and include copious amounts of organic matter, such as well-rotted manure, compost, or peat moss, to get it in good physical shape. This organic material serves as a storehouse for plant nutrients, aids in maintaining good tilth, and helps to hold moisture. Organic matter applications are very beneficial for sandy soils.
Earthworms will be drawn to composted manures, keeping the soil well-aerated, which will benefit your plants. Utilizing organic materials will result in a reduction in the need for synthetic fertilisers. In general, applying 2-3 inches of organic matter to the soil’s surface and properly blending it in will produce favourable outcomes.
WHEN TO PLANT: In warmer climates, daylilies can be effectively divided or planted at any time of the year. Planting needs to be done early enough in other parts of the country so that roots have time to form before winter. A lot of gardeners transplant plants right after the blossoming season is through. When planting during a hot, dry spell, it’s best to water the plants until healthy growth returns.
Moving daylilies is possible when they are in bloom. Moving during the flowering season has the benefit of making colour groups easier. To enable for speedier plant growth with the least amount of stress to the plant, it is advised that extra leaves and scapes be removed.
Strong varieties respond to division every three to four years. DIVIDING PLANTS Competition could weaken the clump if left for a longer period of time. It normally takes a lot of force to separate old clumps. Some plant varieties need to be cut with a knife.
Trim the leaves down to 6 to 8 inches. You’ll see that many cultivars could have varying-appearing roots. This is a varietal trait; some have larger roots, while others have extremely thin roots.
When preparing a bed for planting, attempt to trim and get rid of any tree roots. The water and minerals that daylilies require to thrive are sometimes taken from the soil by tree roots.
About the same depth as the original plants are used to plant new ones. The white leaf base, which denotes the components that were underground, can be used to calculate the original depth. As a general guideline, plants should be positioned so that their crowns, or the intersection of their roots and leaves, are no deeper than one inch below the soil’s surface. Soil over the roots, making sure to leave a small dip to facilitate irrigation. Water the plants right away and keep doing so until they are well-established. Daylilies may experience stunted growth, poor flowering, and yellowing or browning of the leaves if they are planted too deeply. Make sure you never plant too deeply by checking.
MULCHING: Mulching has the advantageous benefit of keeping moisture in the soil and deterring weed growth over the summer. Keep the ground moist; if the mulch is left in place, it is nearly impossible to water the ground. Any number of materials, including pine straw, aged sawdust, pine bark, wood shavings and chips, decomposed leaves, and decomposed grass clippings, can be used for successful mulching. After everything has settled, the mulching material should be between one and two inches thick. If utilising mulching materials, make sure to PH-test the soil once a year.
WATERING: During the blooming season, watering is essential if you want your plants to grow and produce good scapes and flowers. Every few days throughout blooming season, we water the plants. This maintains the plants healthy and green, and the blossoms big.
Daylilies grow far better when fertilised twice a year. Once in early March (for our region) and once more in October or November, following the completion of the fall division and replanting. Applying three light feedings throughout the year—in the fall, spring, and after blooming—might be preferable in sandy soils. The fertiliser 10-10-10, which is balanced, gives us the finest results. Milorganite, which is activated sewage sludge, is another product we use.
Few insects pose a threat to daylilies. You can stop thrips or spider mite attacks by using an insecticide that your neighbourhood garden supply store suggests. Try releasing ladybugs into the garden if you’d rather avoid using chemical pest control. Remember that pesticides and fungicides are hazardous and should always be handled carefully. Always adhere to label instructions and keep insecticides out of the reach of children by keeping them in secure locations.
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.
Which month should daylilies be planted?
There aren’t many perennial plants that are simpler to grow than daylilies. Due of its low maintenance requirements and extensive colour options, it is a favourite 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 colours, some kinds have ruffled petals (including purple). For season-long flowers, plant a blend of early-, mid-, and late-season kinds “Reblooming cultivars will maximise 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 colour 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 fertiliser 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.

What occurs if lily bulbs are buried too deeply?
Your lily bulbs may not sprout at all throughout the growing season if they are planted too deeply. Furthermore, lily bulbs planted deeper than 8 inches (20 cm) will provide fewer or no blossoms. In other words, the majority of the plant parts on your lilies will be stems and leaves. Avoid burying your bulbs too deeply if you want flowers that look nice.
- If lily bulbs are buried too deeply, they might not grow up.
- Your bulbs may produce more leaves and stalks than flowers if you bury them too deeply.
In the end, it is generally preferable to sow lily bulbs slightly deeper than shallower. Deep planting will keep squirrels and other garden scavengers from digging up the bulbs. Additionally, planting deeply will keep the bulbs sheltered from severe rains. Your plants ought to thrive as long as you follow the 8-inch depth rule.
