Landscaping & Nursery Information for Home Gardeners
Daylilies thrive in a hot, dry semi-desert climate. Daylilies feature strap-like, arching foliage that provides strong texture in the garden from spring through fall. These graceful leaves surround sturdy stalks of flowers that add an exotic element to the garden. The trumpet-shaped blooms appear in a multitude of colors -- from pastel tones to fire-engine reds and rich purples. The name daylily indicates that individual flowers normally last for only a day, although some new hybrids last two or three days. Each plant produces many flowers, so there rarely is a shortage of color.

You can expect great returns on your investment in daylilies. They grow vigorously and ask little in return from the gardener. Plant daylilies in sunny areas of the garden. They tolerate light shade, but bloom more freely in full sun. Amend soil at planting time by incorporating organic material to a depth of 12 to 14 inches. Daylilies are somewhat drought tolerant, but occasional deep watering results in better growth and bloom. Daylilies increase in size yearly, and may need to be divided every three to four years. This task is easier to accomplish before the individual clumps become too large and difficult to handle. Division can be done in the spring as new growth emerges, or late in the summer after flowering.

Nearly 30,000 daylily hybrid cultivars are available. Varieties vary by overall plant size. Some are compact and short -- 12 to 14 inches, while larger varieties can grow much larger -- 36 to 40 inches. Darker red and purple-flowered varieties may fade quickly in very sunny areas, so you may want to place them in lightly shaded areas or areas that are shaded in the afternoon. Evergreen varieties of daylilies are not reliably hardy in Colorado.
 

DAYLILIES--PLANTING

Daylilies should be planted in a well-drained, high organic matter soil. Plants can be planted in sun to partial shade, though blooming potential increases in sunny environments. The soil pH should be 6.0 to 7.0.

Plant preferably in the early spring or after plants bloom, but they will usually tolerate planting any time the soil is workable.

Space daylilies 1 1/2 ft. apart for smaller varieties and at least 2 ft. for the larger ones. Spread the roots out  in the bottom of the hole partially filled with good compost and make the top of the crown even with the soil surface. Water them well, and give them a dash of fish fertilizer. Firm soil around roots. 
 

DAYLILIES--SEED PODS

Seed pods will form on daylilies if old flowers are not pruned off. Pods may form viable seed, though unless you're a breeder it is hard to determine what the outcome will be.

Removal of the seed pods may increase the blooming power of repeat daylilies such as Stella de Oro. Seed pods should also be removed to increase the stored carbohydrates in the root system for next year's bloom.
 

DAYLILIES Dividing and Cultivating

Daylilies should be divided every three to five years to keep blooming levels high. Each bloom stalk usually signify two plants the following year; therefore, a clump producing five stalks will contain ten plants the following year.

Ideally, plants are divided in early spring as plants emerge or after they bloom, but they may be transplanted at any time. Dig clumps carefully. Wash the roots, then separate plants with a sharp knife or spade. Remove dead or diseased plants. Roots may be cut into pieces, each of which must have an "eye" or growing point.

When transplanting post-blooming plants, cut back tops by half to limit wilting.
 

DAYLILIES Diseases and pests

Daylilies are quite disease-free and very easy to maintain. Thrips are easily controlled with Malathion, and they suffer few other problems.
