Did You Know?
1. Did you know that the Asiatic lily (Lilium asiaticum) is not only beautiful, but also has a fascinating history? Dating back to ancient Greece, the Asiatic lily was considered a symbol of purity and innocence, and was often associated with the goddess Hera.
2. If you’re wondering what to do with your Asiatic lilies after they have finished flowering, here’s an interesting fact: The leaves of the lily continue to photosynthesize and gather energy even after the flowers have faded. Therefore, it’s essential to refrain from removing the foliage too early, as it plays a vital role in replenishing the bulb for next year’s blooms.
3. Asiatic lilies are not only known for their vibrant colors but also their resistance to deer. These elegant flowers have a natural toxin called lycorine, which deters deer and other animals from grazing on them. So, if you have a deer problem in your garden, planting Asiatic lilies might be a smart choice!
4. Here’s a little-known fact about Asiatic lilies: The bulbs can be consumed by humans, but with caution. In Far East Asia, specifically China and Japan, the bulbs are occasionally used in traditional medicine and cooking. However, ingestion in large quantities can be toxic, so it’s always important to seek expert advice before trying this at home.
5. Lastly, Asiatic lilies have an impressive array of cultivars, with over 3000 named varieties! From solid colors to vibrant patterns, these lilies offer a wide range of options for gardeners and flower enthusiasts. Whether you prefer the classic white or yellow varieties or are looking for something more exotic and unique, there’s an Asiatic lily to suit every taste.
Removing Asiatic Lily Flower Heads
After the vibrant and stunning display of colours that Asiatic lilies bring to your garden, it is important to properly care for them to ensure their health and future growth. One crucial step in post-flowering care is the removal of the flower heads.
By doing so, you not only encourage the plant to focus its energy on developing strong bulbs but also maintain the overall aesthetic appeal of your garden.
When removing the flower heads, make sure to use clean and sharp gardening shears. Start by cutting the stem approximately 2-3 inches below the spent blooms, taking care to avoid damaging any buds or new growth that may be present. This encourages the plant to conserve its energy and direct it towards bulb development rather than seed production.
Allowing Foliage To Die Back Naturally
Asiatic lilies rely on their foliage to absorb sunlight and convert it into energy through photosynthesis. It is crucial to allow the foliage to die back naturally before cutting it back completely. This process typically takes around six weeks.
During this time, the leaves turn yellow and wither away as the plant prepares for its dormant phase. It is important to resist the temptation to remove or trim the foliage prematurely, as this can disrupt the natural cycle of the plant and hinder bulb development.
By allowing the foliage to die back naturally, the plant is able to store essential nutrients for the following year’s growth. The dying leaves also provide protection to the bulbs during the harsh winter months.
Proper Stem Cutting And Winter Storage For Asiatic Lilies
Once the foliage has completely died back and turned brown, it is safe to proceed with cutting back the stems. Before doing so, it is important to ensure that the stems have become hollow and brown. This indicates that the plant has completed its natural life cycle for the season.
Using clean and sterilized gardening shears, cut the stems near the ground, leaving a small portion above the soil surface. This helps to protect the bulbs during the dormant phase and prevents any moisture from seeping into the bulb.
Leaving the bulbs in the ground or pots during winter is crucial for the overall health and growth of Asiatic lilies. These lilies require a cold dormant phase to stimulate future growth and ensure vibrant blooms in the following seasons. Asiatic lilies are hardy bulbs and can endure extremely low temperatures, such as -20°C, without harm.
Ensure that the planting site offers proper drainage to avoid bulb rotting during the winter months. Standing water can adversely affect the lilies’ health and lead to root rot. One effective way to prevent waterlogging is by tilting pots on their side or placing them under shelter to shield them from excess rainfall or snow accumulation.
Ensuring Proper Drainage For Lily Bulbs
Proper drainage is essential for the health and longevity of lily bulbs. When planting Asiatic lilies, it is important to choose a location with well-draining soil or create raised beds to facilitate drainage. Accumulation of water around the bulbs can promote fungal diseases and rotting.
If you are growing lilies in pots, make sure that the containers have adequate drainage holes at the bottom. This allows excess water to drain away, preventing waterlogging and potential damage to the bulbs. Additionally, using a well-draining potting mix enriched with organic matter can further improve drainage.

Water lilies deeply but infrequently is another key factor in maintaining proper drainage*. By allowing the soil to dry out slightly between waterings, you can prevent excessive moisture that may harm the bulbs.

Dividing And Replanting Lily Bulbs
After a few years, lily bulbs tend to multiply and become crowded, resulting in reduced flowering and overall vigor. At this point, it is necessary to divide and replant the bulbs to ensure continuous healthy growth and abundant blooms.
To divide the bulbs, carefully dig them up using a garden fork or spade. Gently shake the excess soil off the bulbs and inspect them for any signs of damage or disease. Trim off any damaged or soft portions, making clean cuts with a sharp knife.
Divide the bulbs by separating the offsets or bulblets from the main bulb. Each offset should have its own intact roots and shoots. Replant the divided bulbs in well-prepared soil, spacing them adequately to allow for future growth. Ensure that each bulb is positioned with its growing point facing upward, just below the soil surface.
By dividing and replanting the lily bulbs, you not only rejuvenate their growth but also provide them with more space and resources to thrive. This process should ideally be done during the dormant season, either in early spring or in the fall.

Frequently Asked Questions
What to do with Asiatic lilies after bloom?
After Asiatic lilies have finished blooming, it is important to remove the faded blossoms. However, it is recommended to leave the foliage in the bed until it has turned brown. This allows the old leaves to continue gathering nourishment for the bulb, ensuring a vibrant display of blooms in the following year. Alternatively, if you want to enjoy the beauty of Asiatic lilies indoors, you can plant the bulbs in containers during the winter season. This way, you can have the pleasure of seeing these stunning flowers bloom the following spring, right within the comfort of your own home.
What to do with lilies when finished flowering?
Once lilies have bloomed, it is crucial to deadhead them by either pinching off the spent flower or using sterilized pruning shears if necessary. By removing only the flower heads, you help divert the plant’s energy towards new growth and encourage a healthy cycle of blooming. Taking this simple step will ensure a stunning display of lilies in your garden year after year.
Can you cut back Asiatic lilies after blooming?
Yes, it is important to wait until the foliage of Asiatic lilies has turned brown in the fall before cutting them back. This is because while the stems and foliage are still green, they are able to continue photosynthesizing and storing energy into the bulbs for the following season. By waiting until the foliage has turned brown, you ensure that the bulbs have received the necessary nutrients and energy to thrive in the next growing season.
Do Asiatic lilies bloom more than once?
No, Asiatic lilies, like most bulbs, only bloom once per year. They follow a natural cycle that requires a cool winter dormancy period of at least 8 weeks before they can flower again. Typically, each plant will bloom for a short period of 2 – 3 weeks out of the year, adding to their allure and making their bloom time even more special.
