Daylilies are an easy, inexpensive, and pretty perennial to grow in your garden. They can be divided into smaller clusters that you can share with friends, or use to expand your own collection. Trim the daylily leaves first before digging out the clump. Then, divide the clump into smaller groups of fans by untangling the roots. Next, replant your new divisions of daylilies, and with a bit of water and sunshine they will be flourishing in no time!


DAYLILY CARE

Deadheading:

Remove spent flowers regularly to keep them looking their best. To avoid seed pods from forming, make sure you are getting the entire flower and not just the petals. Deadheading is critical for subsequent flowering in reblooming types. Some say that because of the number of blooms they produce and the fact that they only last one day, deadheading can be a lot of work. (Note: Be careful with the darker purple varieties, they can stain your hands or clothes.)

Maintenance:

Remove yellowed or dead foliage from the base by grasping firmly and giving a quick tug. After all blooming is done, plants can be sheared to the level of new growth or 6 to 8 inches from the ground and stems cut back to the base. Keep them watered well and you’ll get decent regrowth in 2 to 4 weeks. For reblooming types, simply removing dead or yellowed leaves is preferred over shearing because new flower stalks may be cut off. In mild climates, plants may remain semi-evergreen, and cutting back should be done in early spring before flower stalks appear.

Daylilies prefer moist, average to rich, well-drained soil. They will tolerate poor soil, but won’t tolerate poor drainage.

Amendments & fertilizer:

Daylilies benefit from a balanced fertilizer and appreciate some extra nitrogen in the spring. Fertilizing once or twice during the growing season (spring) and once in fall will encourage strong growth, larger bloom size, and winter hardiness.

Watering:

They will perform best with consistent watering—about 1 inch per day. It is important to water plants regularly in spring when scapes and buds are forming and also while blooming.

Dividing:

Sparse flowering can be a sign of overcrowding. Dig up and divide clumps every 3 to 4 years, or every 2 years for reblooming types. Dig them up in early spring before blooming or late summer after blooming. Cut or pull the crowns apart carefully and replant.

Pests & diseases:

Although seldom bothered by pests, aphids, spider mites or thrips may attack flower buds or foliage. Slugs and snails can also be attracted to tender foliage. If daylily rust (a fungus that damages foliage) is a problem, you may want to consult a local nursery for rust-resistant types to grow in your area.

Deer & rabbits:

Daylilies are usually safe from rabbits. However, they are a favorite of deer, so set up deterrents if needed.


These Daylilies Bloom All Summer

Bring sunshine yellow to your garden this summer.

No matter if you're a wet-behind-the-ears beginner or a grizzled veteran like Grumpy, daylilies are among the easiest perennials to grow—no matter where in the South you live. All they need are full to part sun and well-drained soil and you're set. Most, though, bloom for about a three-week period in summer and they're done. That's why Grumpy enjoys growing reblooming daylilies like this one.

It's called ‘Happy Returns,' a very apt description, because it doesn't bloom just once. It blooms off-and-on from May through September in my garden, and that makes me very happy. Bright yellow blooms, 3-1/2 inches wide stand on 18-inch stalks above compact tufts of foliage. I photographed these last Saturday. Beautimous!

Another excellent feature of this plant is how quickly it multiplies. All you see here I grew from a single plant set out about seven years ago. That first plant grew into a nice-sized clump in two years. I then divided the clump into eight smaller ones in early spring. Now those clumps are as plump as the first and I enjoy hundreds of blossoms in a front yard border.

Maybe yellow isn't your color, though. That's OK. Reblooming daylilies come in lots of different colors and sizes. Among them – ‘Apricot Sparkles' (soft-apricot blooms, 4-inch flower, 18 inches tall), ‘Dublin Elaine' (double light pink, 5-1/2 inches, 32 inches tall), ‘Earlybird Cardinal' (watermelon-red, 4 inches, 21 inches tall), ‘Frankly Scarlet' (scarlet, 4-inches, 24 inches tall), ‘Janice Brown' (light pink with rose eye, 4-inches, 21 inches tall), ‘Pardon Me,' (burgundy-red, 3 inches, 14 inches tall), and ‘Plum Perfect' (plum-purple, 3-1/2 inches, 24 inches tall).

"That's great," you say, "you've excited me beyond all human understanding, but where can I buy reblooming daylilies?" Lot of places, including better garden centers and local daylily farms (it's surprising how many there are). If you strike out there, Oakes Daylilies is a great online source.

WATCH: Here's Everything You Should Know About Daylilies

Daylilies have few pests other than deer, but one I've noticed in my garden is a small, orange-red and black insect called a milkweed bug. It's an easy bug to spot because of its color and because it moves quickly to hide when it sees you coming to squash it. It damages daylilies by sucking the sap from unopened flower buds. The targeted buds turn yellow, shrivel, and drop before opening. I lost an entire flush of blooms on ‘Happy Returns' before I realized what was happening.


Colorful daylilies for your summer garden

Daylilies are colorful, easy to grow and will shine in many flower garden conditions. Their botanical name, Hemerocallis, means “beauty for a day” (from Greek) because each individual flower lasts only a day, thus daylily. So why grow a plant with flowers that last only a day?

Well, for one thing, an established daylily grows many scapes (flower stems) that produce a profusion of buds that keep the plants in bloom for weeks.

There has been a revolution in daylily breeding over the past few years, resulting in new colors and forms. The plants are stronger with lots more flowers over a longer period of bloom. There are more than 60,000 registered cultivars.

Daylilies – versatile and easy garden perennials

Gardeners love them for their rainbow of colors (they flower in every shade except blue) and many shapes and sizes.

They make versatile garden plants too: you can have Hemerocallis in bloom from late spring until autumn.

A well-established clump produces many buds and new flowers daily for a month or more. The plants are clump forming, herbaceous perennials with fibrous or somewhat tuberous roots. Grow them in well-drained soil, amended with manure or compost.

For best performance give them full sun, at least six hours of sun a day. If you plant them in too much shade, you’ll get more leafy growth with fewer flowers.

How to use Hemerocallis in your perennial garden

Besides serving as specimen plants, these perennials excel at providing splashes of color in shrub borders and perennial flowerbeds.

They also make excellent ground covers on slopes, where they can provide erosion control.

They look particularly nice planted against fences, decks or patios, steps and even driveways. To allow them room to thrive, don’t plant them too close to the roots of broad-leafed or evergreen trees.

The plants can range in height from eight inches to five feet, and flower size can be as small as two inches or as large as eight inches.

They often bloom the year they are planted, even from a relatively small size, but they will grow rapidly to form dense clumps and they tend to be long-lived. The scape is a leafless stalk, which bears the flowers. Most have two or more branches, each producing several flower buds.

A reblooming daylily will have an extended flowering period or more than one bloom season – some bloom early (May or June) and repeat in the fall – others have a succession of bloom periods, one shortly after another for several months.

Deadheading or removing the scape (or stalk) will encourage rebloom. Learn more: Daylily planting and care tips.
