Hello, I have had a glorious Asian lily for 2 years now and every year I had a long stem, second year 2 stems of about 60 or 70 cm each and great big flowers. This year, the oldest of the stems has grown about 20 cm and has stopped growing. The stem is very thick, and the leaves seem to have crowded themselves at the top of the stem. They are curly as well, but no spots or signs of being eaten. There are some holes here and there but I haven’t seen any pests. I had some red beetles last year but I collected all of them and their babies and haven’t seen any this year. The younger stem (his 2nd year) is growing normally and except a few curly leaves, I don’t see anything wrong with it. What could be the cause. May I mention that I watered it with the hose about a month ago and the water was cold. It hasn’t suffered any other shocks. What could be the problem?
Distorted leaves could indicate pests or disease.
Since you see some signs of pests eating leaves; go ahead and treat the plant with Neem Oil.
Neem Oil is organic and is safe for people, pets and Bees!
I would treat every 3 days for 2 weeks.

I have Asiatic lilies (pale peach color). They bloom for a few weeks late Spring/earlySummer. Can you give me suggestions what flowers to plant with the lilies so I have blooming flowers into Fall. The garden gets sun about 5 hours a day.
Sure, All of the plants in the article I am providing will bloom in fall, and survive in your area. The second half of the list are annual options as well.

I purchased potted lilies blooming from the nursery. The flowers have fallen off now. Do I need to prune the flower stems or leave them as is?
You can tidy them up around the spent flowers but the leaves need to stay to take up energy for the bulbs. Here's more:

When the Asiatic Lily is done blooming, the leaves turn brown from the bottom up. What do I do next?
It sounds like something has happened that should have! Usually, the flowers will fade and drop, while the foliage remains until the cold sets in. They will normally die from the tops down.
Has it been overly wet? This sounds like it failed to take into its spot and may have succumbed to an infection.
I would treat the area with a fungicide, and start over next Spring. You can still plant something else in the spot temporarily, but wait until the infection is gone (usually just a few weeks, so it shouldn't be an issue when it comes to Spring) to plant another Asiatic lily.

I bought it from a nursery 6 days ago. The plant is placed in partial shady location.
This plant was, likely, forced to bloom. They will not normally bloom at this time of year. With that being said, the failure to bloom properly is more than likely due to many environmental factors at this time.
They will also bloom better the more sun that they receive. If it does not bloom by summer time, then you may need to put it in a sunnier spot, or add horticultural lighting.

What should I do with them because they shouldn't be growing yet its western Illinois
They are hardy in your area, and should have been wintered outdoors. The cold temperatures will keep them dormant. For now, you may need to put them under horticultural lighting until they can go outside.

It is getting taller and taller inside. Not enough flight, etc. what shall I do. It is about one to two months early for outside ,
This needed to be planted in the Autumn so that it could get a chill period for best flowering.
You can plant now, but expect diminished flowering for the year, since it did not receive the chill period required.
