Planting, Growing, and Caring for Lilies

With stunning star-shaped flowers, lilies add elegance and fragrance to any garden. Enjoy their colorful blooms from spring through the first frost by blending early-blooming, mid-season, and late-blooming lilies into your garden. Learn more about choosing, planting, and growing lilies.

About Lilies

Everyone loves lilies! Grown from bulbs, lilies are perennials that require minimal care if planted correctly. Most lilies do well in containers and look spectacular in a vase.

True lilies belong to the genus Lilium and grow from plump, scaly bulbs. Several popular lily species exist, including Orientals, Asiatics, Orienpets, and Species types.

We say 鈥渢rue鈥 lilies because there are also plants, such as daylilies, peace lilies, and canna lilies, which have the term 鈥渓ily鈥 in their common name, but they鈥檙e not actually lilies at all. They do not grow from bulbs but are in a different plant genus. Water lilies aren鈥檛 lilies at all, and neither are lily-of-the-valley.

With 8,000 or so varieties, lilies parade an endless range of colors, shapes, heights, and bewitching scents. Lilies have six plain or strikingly marked tepals (鈥減etals鈥) and are often trumpet-shaped, sitting atop a tall, erect stem with narrow, long, lance-shaped leaves. They come in many beautiful colors, including pink, gold, red, orange, and white.

Most lilies also take readily to containers at home in formal and naturalistic settings. Plus, they make excellent cut flowers! 

To create a sequence of Lily blooms in your garden, remember that Asiatics generally flower first, followed by Orienpets and then Oriental varieties.

  • Asiatic lilies (Lilium sp. - 鈥淎siatic hybrids鈥) are the earliest to bloom (usually in May or June), right after peonies. They are also the easiest to grow, as long as they are planted in well-draining soil, not waterlogged. They are the shortest type of lily (about 2 to 3 feet tall) and come in many colors, from pastel to tropical. Hybrids come in pure white, pinks, vivid yellows, oranges, and reds; heights are from one to six feet. Intense breeding has erased much of the Asiatics鈥 fragrance, but despite their lack of perfume, they are a favorite with floral arrangers.
  • Oriental lilies (Lilium sp. - 鈥淥riental hybrids鈥) have that famously intoxicating fragrance. They are tall and stately (4 feet), and tend to grow more slowly. Oriental hybrids bloom in mid- to late summer, just when Asiatic lilies are beginning to fade. Orientals are always a striking choice, producing masses of huge white, pink, red, or bi-color blooms. They make wonderful cut flowers that fill even the largest rooms with spicy scents.
  • Easter lilies (Lilium longifolium) are most commonly grown indoors as a holiday plant. As their name suggests, they are typically forced into bloom around Easter, in March or April. Outdoors, they are better suited for warmer regions of North America, where they can be planted in the garden after blooming has finished. These are generally hardy to Zone 5 (and to Zone 4 if given 1 to 2 feet of mulch in autumn for winter protection). Learn more about Easter Lilies.
  • Trumpet lilies (Lilium sp. - 鈥淭rumpet hybrids鈥) are similar to oriental lilies, producing many blooms with a nice scent. Their flowers tend to be smaller and more closed (like a trumpet) than those of the other lilies.

There are other lilies out there, of course, such as tiger lilies (Lilium henryi) and Turk鈥檚 cap lilies (Lilium superbum), as well as hybrids like 鈥Orienpet鈥 (Oriental + Trumpet) and 鈥LA鈥 lilies (Easter + Asiatic).

Planting

Lilies need lots of sun. For dependable blooms, lilies should get 6 to 8 hours of direct sunlight daily (aka 鈥渇ull sun鈥). If it鈥檚 too shady, the stems will attempt to lean toward the sun or get spindly and fall over. 

Also, a well-drained site is critical. Water trapped beneath the scales may rot the bulb. How can you tell if your site drains well? After a good rain, find a spot that is the first to dry out. Enrich the soil with leaf mold, compost, or well-rotted manure to encourage good drainage. Learn more about soil amendments and preparing soil for planting.

Most popular varieties prefer acidic to neutral soil, but some are lime-tolerant or prefer alkaline soils (e.g., Madonna lilies).

When to Plant Lilies

Lilies are commonly planted in the fall but can be planted in the spring in areas with harsh winters.

  • In the fall, plant at least four weeks before your first fall frost date. Bulbs planted in the autumn will have well-established roots in the spring. The bulbs benefit from a winter chill to produce big blooms.
  • In the spring, plant them as soon as the threat of frost has passed.
  • Container-grown lily plants can be planted anytime during the early summer.
  • Buy the bulbs close to planting time. Because lily bulbs don鈥檛 go dormant, they will deteriorate over time, so don鈥檛 plan to buy bulbs in the fall and wait until spring to plant them.

How to Plant Lilies

  • Loosen the soil to a depth of 12 to 15 inches.
  • Plant lilies three times as deep as the bulbs are high. The deep planting encourages the developing stem to send out roots to help stabilize the plant and perhaps eliminate the need for staking. Also, deep planting keeps lily bulbs cool when temperatures soar.
  • Set the bulb in the hole pointy side up. 
  • Fill the hole with soil and tamp gently (Got critters? Bury the bulbs in wire cages to protect them from getting eaten).
  • Space bulbs at a distance equal to three times the bulb鈥檚 diameter (usually about 8 to 18 inches apart, depending on the variety).
  • If space allows, plant lilies in groups of three to five for visual appeal; crowding leads to poor circulation and gray molding.
  • Water thoroughly at the time of planting.

Growing

How to Care for Lilies

  • During active growth, water the flowers freely, especially if rainfall is less than 1 inch per week.
  • Keep lilies mulched so that their roots are cool. The mulch should feel moist but not wet. Read more about mulching.
  • Apply a high-potassium liquid fertilizer every 2 weeks from planting until 6 weeks after flowering.
  • Apply a thin layer of compost each spring, followed by a 2-inch layer of mulch.
  • Stake tall lilies.
  • Lilies do not bloom more than once per season, but you can remove the faded flowers so that the plants don鈥檛 waste energy making seeds.
  • After the lily blooms, you can also remove just the stem itself. However, do NOT remove leaves until they have died down and turned brown in the fall. It鈥檚 very important not to cut back the leaves until the end of their season because they help provide nourishment to the bulb for next season鈥檚 blooms.
  • Cut down the dead stalks in the late fall or early spring.
  • Before winter, add 4 to 6 inches of mulch, simply to delay the ground freeze and allow the roots to keep growing. Leave the mulch until spring, once the last hard frost has passed. See your local frost dates. See your local frost dates.
    • If your region doesn鈥檛 have snow cover, keep the soil moist in winter.
  • When lily shoots grow through the mulch in the spring, start to remove it gradually.
  • Divide plants every 3 to 4 years as new growth begins in the spring. Just lift the plants and divide the clumps. Replant the new bulbs, adding some compost.

Harvesting

Displaying Lilies in Vases

  • Lilies make wonderful cut flowers. However, avoid cutting off more than a third of the stem. Taking more than that can reduce the plant鈥檚 vigor and longevity since the plant needs its foliage to create energy.
  • If you are growing lilies strictly for cut flowers, consider planting them in a designated cutting garden, where you can plant fresh bulbs each year.
  • When cutting lilies, choose those with buds that are just about to open, with a bit of the flower color showing. The higher-up buds will open as the bottom ones fade.
  • Just one lily stem in a vase can be a show-stopper.
  • As soon as you get lilies inside, trim the stem ends an inch or so, making a diagonal cut with a sharp knife.
  • If you worry that the orange pollen of lilies might cause stains, simply snip off the stamens in the flower鈥檚 center.
  • Before arranging in a vase, remove the lower leaves on the stems so that no foliage will be underwater.
  • A good lily arrangement will last two or more weeks. Change the water every few days. Learn how to keep cut flowers fresh.
  • To help prolong the flowers鈥 life, add cut-flower food to the water. Lilies require only half the amount of food recommended for other flowers.
  • It’s important to note that lilies are highly toxic to our feline friends. If you have cats, we do not recommend cutting lilies to bring inside because even the pollen can cause tragic consequences. Learn more about Plants That Are Toxic to Cats, Dogs, and Other Pets.

How to Save Your Easter Lilly

These stunning seasonal potted blooms can be enjoyed in the garden for years. Allow the flowers to fade and remove each in its turn. Set the pot in the sun and treat it as a houseplant, fertilizing when watering until the leaves are yellow. In mid-May, remove the bulb from its pot and plant it outdoors in a protected but sunny spot. New growth will soon emerge. Typically, during the first outdoor season, Easter lilies bloom in late September. In the ensuing years, they will reach a height of about 3 feet.

Wit and Wisdom

  • The name 鈥渓ily鈥 can be misleading because many other plants use it besides true lilies. Daylilies and water lilies aren鈥檛 lilies at all, and neither are lilies-of-the-valley or lilyturf. With so many other plants using the name 鈥渓ily,鈥 it seems that identity theft has existed since long before using computers and credit cards!
  • Easter lilies can be planted in the ground in the spring. They may survive several years if you mulch them heavily in the fall, especially in northern regions. If they survive, they’ll bloom in late summer.
  • In a flower bed, lilies prosper in the presence of low-growing plants that protect the lilies鈥 roots from drying out.

Pests/Diseases

  • Gray mold is sometimes a problem, especially in a wet, cool spring or summer. Make sure lilies are not crowded and have plenty of air circulation. Rot can also be a concern.
  • Viruses, spread by aphids, may be troublesome, although some cultivars are virus-tolerant.
  • Red lily beetles, slugs, and snails may occur.
  • Deer, rabbits, voles, and groundhogs may eat entire plants. If these critters are a problem, plant the bulbs in buried wire cages to protect them from getting eaten.
