How to Grow Asiatic Lilies
Asiatic lilies are some of the most beautiful flowers that you can grow. I love to walk in the garden and see the new blooms, and my garden just wouldn't be complete without them. These are my favorite flowers next to daylilies (which aren’t really lilies at all). Here you will find all the information you need to grow Asiatic lilies.
Once you plant lily bulbs or plants, they will give you pleasure for years to come and multiply and become even more beautiful.
They are grown from a hardy bulb that multiplies quickly and takes little care. They come in many sizes, heights, and shapes. Lilies are called bulbs but are really tubers with fleshy scales that never go into dormancy like other bulbs that you might be familiar with.
Choosing the Right Lily Bulbs
The Asiatic bulbs are the first to bloom and come in a large variety of colors. Different varieties will bloom at slightly different times. Many types are available, but always check that they are hardy in your planting zones. Some lilies aren’t hardy in the north, and some can’t be grown in the deep south.
Never buy bulbs that have been marked down for clearance in the stores. These are usually completely dried out. Buy good, fresh bulbs. If the bulbs are too dry, they won't even sprout.
Planting the Bulbs
The bulbs can be planted in either spring or fall. In the fall, they can be planted until the soil freezes.
Lilies can be planted in full sun or partial shade in a place that has good drainage. At least six hours of sunlight a day is preferable. A spot where the lilies get morning or late afternoon sun is best. Lilies will thrive in the shade, and I have grown them in shady areas. But you are taking a chance that they may not bloom well there, and the plant is usually shorter. In the shade, they also have a tendency to lean towards the sun. I have several that I need to move to a sunnier area since they are leaning almost to the ground.
The bulbs should be planted as soon as possible, because they dry out easily. For a nice looking stand of lilies, it usually takes three or more tubers. These will multiply, and eventually you will have a really nice grouping. Plant them among other flowers that will shade the bulbs.
Check the bag that the lilies were purchased in for planting depth. Something nice to have, but not necessary, is a bulb planter. You just press it into the ground and it will make a hole at just the right depth.
Caring for Asiatic Lilies
Fertilize your plants with a slow-release food in the early spring. Use a fertilizer that is recommended for lilies. Check the back of the bags and it will tell you how much to apply to each plant.
Lilies need at least 1” of water per week. Try not to get the leaves or flowers wet when watering, since this can cause disease.
Deadhead the flowers as they start dropping their petals, and don’t allow them to go to seed. Leave the green plants until they turn brown, as this helps feed the bulbs.
After the stalks have turned brown, mulch the plants in late fall to help protect them for the winter. This usually isn’t necessary unless you live in a very cold zone, but it will be beneficial to the plant.
Dividing the Bulbs
If your Asiatics start bloom less frequently, it is probably time to divide the bulbs. The bulbs multiply quickly, and the baby bulbs will drain nutrients and water from the main bulbs. Be careful not to slice into your bulbs when digging, though. Now you can use the baby bulbs for new lily plants.
Remove the largest bulbs first, and plant at least three of these together. The tiny bulbs can all be planted in a spot together for storage until they get large enough to display in the garden.
My granddaughter and I tried our own hand at hybridizing Asiatics. She was just a little girl at the time, and we had a lot of fun. All you need is to take the pollen from one bloom and dab it into another. You'll have no problem getting the pollen out of the bloom. Lilies have so much pollen that the yellow will get onto your clothing if you aren't careful.
If you want to keep track of which plant you hybridized with another variety, you should place a plastic bag over the bloom when you are finished. This will help bees, wind, or other insects from spreading pollen from another bloom.
You can end up with some new colors and fun blooms. Once the seeds are ripe, you'll need to pick them. Plant them in the garden the next year. The little plants look like spikes of grass. You'll need to mark where they are planted, so you don't accidentally pull them out as weeds.
The plants will take about three years before you'll see blooms. This takes patience.

Questions & Answers
Will Asiatic Lilies freeze?

Something is eating holes in my lily buds. Do you know what it is, and what I can do?
I can't say for sure without seeing the culprit. It sounds to me like Japanese beetles or lily beetles. The trouble is that it could be many different insects, and all I can do without seeing them is guess.Helpful 1
Once the petals of Asiatic lilies fall off, do they come back again; or is it just the one bloom?
Asiatic lilies are ready for the winter when the petals fall off and the plant has turned brown. After that, they won't bloom again until next year.Helpful 11
Do Asiatic lilies bloom all summer?
A bloom can last two weeks, but more buds will open. No, they don't bloom all summer, but with proper care, you can get them to rebloom at the end of the summer. Remove the stalks of the faded blooms when the bloom dies. Keep all seed pods removed. If your season is long enough, you can get rebloom.Helpful 5
How do I protect a White Sunny Azore Oriental Lily during the winter in Chicago, IL?
Most Orientals are hardy in your area. I tried to research the variety that you mentioned but came up with nothing. Cover the leaves and check during snow melts that the bulbs haven't been pushed out of the ground.Helpful 2
