How to Plant Lily Bulbs

Depth, spacing & care (Autumn)

Lilies are among the most striking and beloved flowering bulbs in the garden. Their tall stems support large, often fragrant blossoms in a vivid palette of colors—white, pink, red, orange, yellow, and patterned varieties. Some lilies face outward, others nod or trumpet, adding movement and elegance.

Whether used in borders, containers, or as focal specimens, lilies bring vertical interest and theatrical flair. Many are hardy perennials: once planted under the right conditions, they reliably return, multiply, and perform year after year.

How to plant

Plant true lily bulbs in autumn, ideally a few weeks before the first hard frost. This gives them time to settle and establish roots over winter. In regions with cold winters, you can also plant in spring once the soil is workable — though autumn planting generally yields stronger growth.

Where to Plant

Choose a location that receives full sun to part shade. Lilies thrive with “head in the sun, feet in the shade” — strong light above, cooler soil and roots below. The soil must be well-draining to guard against rot; poor drainage is one of the most common reasons bulbs fail to thrive.

Preparing the Soil

Loosen the soil to a depth of about 20–25 cm and remove rocks, weeds, and compacted layers. Improve heavy or clay soils by mixing in compost, leaf mold, or grit to increase aeration and drainage. Work in organic matter to enrich the soil without creating sogginess.

Planting the Bulbs

Set the bulb with its basal plate (root side) downward and the pointed end upward. A general guideline is to plant lilies at a depth of about two to three times the height of the bulb. Space them generously — around 15 to 25 cm apart (or more for larger varieties). For dramatic groupings, plant in clusters or scalloped arrangements rather than straight rows.

After Planting

Water the planting area gently but thoroughly to settle soil and eliminate air pockets. After that, rely mostly on natural rainfall, supplementing only if conditions remain dry. Avoid overwatering, especially while the bulb is establishing.

Spring Growth and Blooming

As spring arrives, foliage emerges first followed by sturdy stems and flower buds. Many lilies bloom in mid to late summer, offering a long display of color and scent. Some types may require staking to support heavy flower heads as they open.

After Blooming

Once the flowers fade, remove the spent flower stalks to prevent seed formation. Leave the foliage intact until it yellows and dies back naturally — this period allows energy to flow back into the bulb. Only trim foliage once it has fully withered. If clumps become crowded and bloom declines, lift and divide bulbs occasionally during dormancy.

Extra Growing Tips


  • Always ensure good air circulation — crowding can lead to disease.

  • In containers, use deep pots and excellent drainage.

  • Mulch lightly to moderate soil temperature and retain moisture.

  • Be cautious: many lilies are toxic to pets, especially cats.

  • To protect bulbs from pests, consider planting in cages or using fine mesh.
