How to Grow Asiatic Lily
Asiatic lilies require very little care once their sun and drainage requirements are satisfied. Asiatic lilies have a three- to five-year lifespan for each bulb, but they multiply quickly, so you’ll always have more. Here’s a closer look at their maintenance requirements and preferences:
Light
Asiatic lilies require full sun to thrive and remain healthy, so place them where they will receive six hours of direct sunlight each day. The best time to expose them would be early in the day rather than late in the afternoon, as extreme heat could make them wilt and get stressed.
A southeast site is preferable to a southwest one unless there is anything to provide shade during the warmest portion of the day. Remember that the genus does not require six hours of direct daylight every day, but rather six hours in total.
If you’re not sure whether a potential lily bed gets enough sunshine, chart your garden, note how much light enters it during the day, and monitor the area to see how much light it receives.
Water
When the weather is typical, established Asiatic lilies require around one inch of water per week. Check whether this requirement has been fulfilled or if you need to apply more irrigation by using a rain gauge or a weather station.
If this is the case, make sure to always irrigate the roots instead of the leaves and blossoms. If you want to prevent fungal diseases and root rot, let your lilies dry out in between watering. Adequate, clean, and free drainage holes are necessary for lilies cultivated in raised beds or containers.

Soil
This suggests a value of roughly 6.5 to 6. Their growth is not facilitated by deep clay and low, marshy conditions.
To improve the texture and quality of your soil, add more compost to the mixture. For optimal effects, apply your amendments either in the autumn for spring planting or in the spring for October planting. The soil becomes more nutrient-rich and fully aerated as a result, which enables the microorganisms to work their magic.
Fertilizing
Fertilizer used early in the spring can encourage big, beautiful blooms and an amazing start to the Asiatic lily season. Choose a balanced, slow-releasing granular fertilizer with an NPK ratio of 10-10-10 to give them the same quantities of potassium, phosphorus, and nitrogen.
Giving the blooms something organic, such as a bone meal or bulb booster, just before they bloom will give them an extra push before they open.
Stem tissue or immature buds could get scorched if over-fertilized. There are no benefits to fertilizing lilies in the autumn. Wait until springtime and repeat the process.
Asiatic Lily Care
Asiatic lilies often don’t require much care and are simple to cultivate. To keep them happy and healthy, though, there are a few maintenance duties you should do.
Mulch
Lilies need bright sunlight for their leaves and blossoms, but they do well with cool, dry roots. The greatest solution to reconcile these two divergent desires is to apply an insulating mulch layer.
Your lilies will feel comfortable if you place two to three inches of organic material—such as dried leaves, pine straw, mixed hardwood, or hay—at their feet.
Deadheading
Unlike most flowering perennials, Asiatic lilies only bloom once a season, so pulling old flowers won’t encourage new development. Still, it will keep everything tidy and prevent petals from collecting around your lilies’ stems, which could promote mildew or deterioration.
Use a sterile bypass pruner for trimming, and instead of letting blossoms fall to the ground, dispose of them by placing them in the compost pile. This will help stop the sickness from spreading.
Cutbacks
Asiatic lilies continue to store energy for the next year through photosynthetic activities after blossoming. It’s crucial to leave the leaves and stems in place until the very end of the season, despite the temptation to trim them as soon as the show ends.
Lilies will begin to turn brown or yellow at the first frost, indicating the start of their dormant season. The moment has come to begin saving money. With a clean gardening tool, trim stems to ground level and compost any good leaves.
Pruning
Pruning Asian lilies is not necessary. Leave the stems and foliage on the plant after they turn green. In the winter, let the foliage naturally die back. Save at least one-third of the stem when cutting flowers for bouquets.
Propagation
The simplest way to propagate Asian lilies is to divide clumps of lilies. When the shoots first sprout, in early autumn or early spring, this can be done. A clean, sharp knife, gardening gloves, and a shovel are required. Asiatic lilies are divided using this technique.
- When propagating Asiatic lilies in the autumn, trim the foliage back to a height of six inches above the earth before splitting it.
- Dig around the lily clump, sliding the shovel under the bulbs and lifting them out of the ground.
- You can either use a hose to lightly rinse the bulbs or give the clump a little shake with your hands to remove extra soil.
- Pull the clump apart at the roots with your hands. Ensure that every newly formed clump has a root system and at least two sets of leaves. If needed, split up clumps with the knife.
- After planting the bulbs, give them plenty of water. Keep the soil moist as the plants regrow.

Common Pests & Plant Diseases
Common plant pests like aphids and diseases like botrytis blight can have an impact on Asian lilies. Small green insects called aphids consume the sap from leaves and plants.
You can treat them with neem oil or insecticidal soap. Use an organic fungicide to treat botrytis blight, which causes brown or tan oval-shaped areas on leaves.
Common Problems with Asiatic Lily
Brown Spots on Leaves
The appearance of brown patches on leaves and flower buds may indicate botrytis blight, which is treatable with an organic fungicide based on copper.
Holes in Leaves
Lily leaf beetles are tiny red insects that can make holes in the leaves of your Asian lily. They are difficult to eradicate. Adult specimens should be physically removed from plants as soon as possible. Do this by removing the leaves and putting the specimens in a container of soapy water.
Hand-remove egg masses from the undersides of leaves; use products containing neem once a week to kill larvae and deter adult beetles.
Leaves Turning Yellow
If the soil does not drain well, your Asiatic lily may develop yellow leaves, which could indicate that it has been overwatered. Reduce the amount of water you add, and wait until the soil is completely dry before adding more.
Should drainage be an issue for you, you might choose to remove the bulbs in the autumn and replant them in a location with better drainage.
Conclusion
Asiatic lilies Plant in a bed or container with loose, organic soil that drains well for the best results. Make sure they have enough ventilation and plenty of sunshine to ward off disease and pests.
Divide every few years to prevent crowding, and plant enough to be able to pinch off a few blossoms for your kitchen vase. Asiatic lilies are easy to grow and a pleasure to have around!

FAQ
Do Asiatic lilies return annually?
Yes, these plants are perennials, and they will grow again every year if given the right care.
Which animals consume the buds of Asiatic lilies?
Chipmunks, mice, squirrels, and voles will occasionally nibble off flower buds; however, this is not a frequent issue. But some species, like cats, are poisoned by Asian lilies.
Are Asiatic lilies toxic to dogs?
Kind of. They can upset a dog’s stomach if consumed, although the symptoms are significantly less severe than in a cat.
