Can You Propagate Lilies? | Yes, 4 Reliable Methods

Yes, you can propagate true lilies (Lilium) using several reliable methods, with division and scaling being the fastest ways to produce new flowering bulbs.

A friend’s towering lily patch is one of the best garden compliments you can get. The good news is that one healthy plant can become many, and you don’t need a greenhouse or a degree in botany to do it. True lilies propagate from bulbs and bulb parts, not from a leaf snipped off in passing. The standard methods ring up from most productive to most patient: dividing mature clumps, collecting the small bulblets that form underground or in leaf joints, and rooting individual bulb scales. Scale propagation takes a few months but can turn a single bulb into dozens of new starts. Choose the method that fits your timeline and how many plants you want.

Method 1: Dividing Crowded Lily Clumps

Dividing an established clump is the most straightforward method and works for gardeners who already have lilies. Most true lilies divide on their own; some Asiatic varieties can produce two to four new bulbs in a year.

The North American Lily Society recommends lifting crowded clumps with a garden fork after the foliage has died back. Gently pull the bulbs apart by hand. Small bulblets are often attached along the underground stem just below the bulb — keep those, too. Replant the separated bulbs and bulblets promptly at the same depth they were growing. Dividing after flowering lets the plant put its energy into root development rather than supporting blooms.

healthy divisions will show firm bulbs with intact roots and no soft spots.

Method 2: Collecting Bulblets and Bulbils

Some lily varieties produce small bulbs called bulblets or bulbils that are ready-made planting stock. Bulblets form along the underground stem every year on varieties that set them, and bulbils form in the leaf axils along the above-ground stem of certain types, like tiger lilies.

Detach stem bulblets in fall when the plant is dormant and replant them directly in the garden or a nursery bed. Bulbils can be collected in late summer to autumn when they are plump and come away with a gentle tug. Plant them in pots about 2.5 cm apart, keep them on a sunny windowsill through winter, and refrigerate the pots for at least a month before planting outdoors in spring if they did not experience cold naturally. Bulbils typically take a year or two to reach flowering size.

planted bulbils will produce a single green shoot the following spring. That shoot means roots have formed.

Method 3: Scale Propagation for More Bulbs

Scale propagation is the most productive method. One firm bulb can yield many new bulblets in a single season by rooting individual scales. This method is ideal when you need a large number of plants from limited stock.

Remove four to eight scales from a firm, healthy bulb in fall when the bulb is dormant. Do not take more — scales store next year’s food supply for the parent bulb. Dust the removed scales and the parent bulb with a fungicide to prevent rot. Place the scales in a sealed plastic bag with slightly damp peat moss or vermiculite. Store the bag at about 70°F out of direct light. Small bulblets will form at the base of each scale within a few weeks. Once bulblets appear, pot them up individually. If wintering indoors, give them 6 to 12 weeks of refrigerator chilling before expecting top growth.

small white bulblets the size of a pea will appear at the broken base of each scale. That is a new plant.

Scale Propagation: Common Mistakes

The single most common failure is removing too many scales from one bulb, which starves the parent of stored energy for the next season. Letting the scales dry out during storage is the second — they need moisture, not a puddle. Protect bags from direct heat or freezing, which can kill the developing bulblets before they emerge.

Method 4: Seed Propagation (For Patient Gardeners)

True lilies produce seed pods after flowering, and those seeds are viable. The North American Lily Society notes seed propagation is slower but works well when ripe bulbils are collected. Sow seeds as soon as they are ripe in a well-draining mix. Seed-grown lilies typically take a year or two to produce a bulb large enough to flower. This method is reliable but requires patience compared to division or scaling.

One garden blog mentions propagating Asiatic lilies from leaf cuttings taken with a sliver of stem tissue and rooted in sand. This technique is not standard advice from official lily societies and has a lower success rate than the methods listed above. Stick with division, bulblets, or scaling for reliable results.

Important: True Lilies vs. Waterlilies

The term “lily” is ambiguous in common usage. The methods above apply to true lilies in the genus Lilium — the plants that grow from bulbs with scaled layers. Waterlilies are entirely different aquatic plants and reproduce differently. The RHS recommends propagating waterlilies by dividing the clump in late spring or early summer, separating sections with at least one young shoot and plenty of fibrous roots, then planting them in aquatic baskets with the growing point at the surface. Waterlily seed is rarely produced by hardy varieties, and when it is, it needs a minimum of 55°F (13°C) to germinate.

Planting Your New Lilies: The Basics

Lily bulbs and bulblets have a clear orientation once you know what to look for. Plant them with the roots downward and the pointed end upward, about 10–15 cm (4–6 inches) deep from the top of the bulb to the soil surface. Space bulbs about 30–40 cm (12–16 inches) apart. After planting, water them in thoroughly and mark the spot so you don’t accidentally dig them up while the bed is dormant.
