Lilies are celebrated for their striking beauty, offering a diverse palette of colors and forms that enhance any garden space. Their elegant blooms and often fragrant presence make them a favored choice among gardeners. It is natural for garden enthusiasts to seek ways to expand their collection of these magnificent plants.
Understanding Lily Propagation
Many garden plants reproduce from stem or leaf cuttings. However, lilies, as bulbous plants, do not respond well to these traditional methods. Successful lily propagation relies on methods utilizing parts of the bulb or natural plant divisions. The most reliable techniques involve propagating from bulb scales, harvesting naturally formed bulblets, or dividing established lily clumps. These methods leverage the lily’s natural growth habits to produce new plants.
Propagating Lilies from Scales
Propagating lilies from scales uses individual scales detached from the main bulb. The optimal time to collect scales is after flowering or in autumn as the plant enters dormancy. Carefully excavate the lily bulb and gently brush away dirt. Using a clean, sharp knife or your fingers, detach healthy, plump scales from the outer layers, ensuring each has a small piece of the basal plate attached.
Wash the scales gently to remove soil and air dry for a few hours. To prevent fungal issues, consider dusting with fungicide powder. Prepare a propagation medium by mixing equal parts moist peat moss and perlite or vermiculite, ensuring it is damp but not waterlogged. Place the scales into a sealable plastic bag with the moist medium, ensuring they are fully covered.
Seal the bag and store it in a warm location, 70-75°F (21-24°C), for six to eight weeks. Tiny bulblets should begin to form at the base of each scale. Once bulblets are visible, move the bag to a cooler environment, around 40°F (4°C), for another six to eight weeks to simulate a chilling period. This chilling promotes root development. After chilling, remove the scales with attached bulblets and plant them about one inch deep in small pots filled with well-draining potting mix.
Propagating Lilies from Bulblets and Division
Lilies can also be propagated from naturally occurring bulblets or by dividing mature clumps. Some lily varieties produce small bulblets along their stems, either below the soil line or in leaf axils above ground. Detach these stem bulblets once they are large enough, typically in late summer or early autumn. Plant them one to two inches deep in a well-draining potting mix.
Other lilies form offset bulblets around the base of the main bulb underground. Separate these when lifting the main bulb, usually in fall or early spring before new growth begins. Each offset bulblet should have roots attached; plant them individually at a depth of two to three times their diameter.
For established, overcrowded lily clumps, division is another propagation method. A single lily bulb can multiply into a dense cluster. Dig up these clumps in early fall or early spring as new growth emerges. Gently separate the individual bulbs, ensuring each has a healthy root system. Replant these separated bulbs immediately into their new locations at a depth typically three times the bulb’s height.
Caring for New Lily Propagations
Caring for newly propagated lily plants involves providing consistent conditions for their initial growth. After planting, water young bulblets or divided bulbs thoroughly to settle the soil. Maintain consistent moisture in the growing medium, keeping it damp but never waterlogged, as excessive wetness can lead to rot. Adequate drainage is essential for healthy root development in these young plants.
Place pots with new propagations in bright, indirect light to encourage steady growth without scorching tender new foliage. Protect them from extreme temperature fluctuations during their initial establishment. Depending on the propagation method and bulblet size, they may need to grow in pots for one to two seasons before transplanting. When transplanting, choose a site with well-draining soil and appropriate sunlight for the specific lily variety.

Understanding Lily Propagation
Many garden plants readily reproduce from stem or leaf cuttings, a common practice for increasing plant stock. However, lilies, being bulbous plants, do not typically respond well to traditional stem or leaf cutting methods for propagation. Attempting to root a stem cutting from a lily is generally ineffective and will not yield new plants. Instead, successful lily propagation relies on methods that utilize parts of the bulb or natural plant divisions. The most reliable and widely used techniques involve propagating from bulb scales, harvesting naturally formed bulblets, or dividing established lily clumps. These methods leverage the lily’s natural growth habits to produce new plants.
Propagating Lilies from Scales
Propagating lilies from scales is an effective method to increase your lily stock, utilizing individual scales detached from the main bulb. The optimal time to collect scales is typically after the lily has finished flowering, or in the autumn when the plant begins to enter dormancy. Carefully excavate the lily bulb from the soil, gently brushing away excess dirt to expose the scales. Using a clean, sharp knife or your fingers, carefully detach healthy, plump scales from the outer layers of the bulb, ensuring each scale has a small piece of the basal plate attached.
After collection, wash the scales gently to remove any remaining soil and allow them to air dry for a few hours. To prevent fungal issues, some gardeners may choose to lightly dust the scales with a fungicide powder, though this is not always necessary. Prepare a propagation medium by mixing equal parts moist peat moss and perlite or vermiculite, ensuring it is damp but not waterlogged. Place the prepared scales into a sealable plastic bag with the moist medium, ensuring they are fully covered.
Seal the bag and store it in a warm location, ideally with temperatures ranging from 70 to 75 degrees Fahrenheit (21-24 degrees Celsius), for approximately six to eight weeks. During this period, tiny bulblets should begin to form at the base of each scale. Once bulblets are visible, move the bag to a cooler environment, around 40 degrees Fahrenheit (4 degrees Celsius), for another six to eight weeks to simulate a chilling period. This chilling helps promote robust root development and subsequent growth. After the chilling period, carefully remove the scales with their attached bulblets from the bag and gently plant them about one inch deep in small pots filled with a well-draining potting mix.
Propagating Lilies from Bulblets and Division
Lilies can also be propagated effectively from naturally occurring bulblets or by dividing mature clumps. Some lily varieties produce small bulblets along their stems, particularly below the soil line or in the leaf axils above ground. These stem bulblets can be gently detached from the main stem once they are large enough to handle, typically in late summer or early autumn. Plant these individual bulblets about one to two inches deep in a well-draining potting mix.
Other lilies form offset bulblets around the base of the main bulb underground. These can be carefully separated when you lift the main bulb, usually in the fall or early spring before new growth begins. Each offset bulblet should have some roots attached, and they can be planted individually at a depth of two to three times their diameter. For established lily clumps that have become overcrowded, division offers another straightforward propagation method.
