When the blooms drop off, you have a bud left. Do these rebloom and will they come back next year?
When all the flowers have faded, you can dead head the lily stem.
Leave the green stem to die down naturally, since this helps feed the bulb for next years flowers.
Your bulbs bloom one time each season.
Here are some links to refresh you on the care requirements.

When should I trim back the green part (which is actually yellowing now) of Asiatic lilies once the blooming of flowers is done? I planted Asiatic lilies this spring that I purchased from gardening center, they were already in bloom. They have stopped blooming but the leaves remain, and they are yellowing. Should I trim them down to the dirt now or wait for the first fall frost? Thanks.
Hi, The biggest problem most people make with their bulbs; regardless of variety of flower, is cutting the leaves off after the flowering stage is done. These leaves Provide the nutrients the bulbs need lying deep in the ground, so leave them on, and when they have all turned light brown, they will basically fall off by themselves, then all you have to do is pick them up..
We live in central Alberta and have had Asiatic lilies in our garden for the last 25 years. We live on an acreage. Some type of animal has started chewing the lily stalks off at the base. Then try dragging it away. It looks like they are after the buds, as we are finding some partially eaten buds. This is happening at night. What little (or big) critter do I have to blame for this? The lilies are coming into full bloom and it is frustrating to see this damage happening.
Its difficult to say. It is unlikely to be a large critter as they will usually nibble from the top down. They are possibly nibbling the base to fell the stalk as they cant reach the buds. Clever rabbits?
Is it safe to transplant Oriental/Asiatic lily trees the beginning of September in Zone 5a?
It is best to leave the lily in place as long as it has green leaves, so that they can photosynthesize and store energy in the bulb for the following season. When the leaves die back, then you can dig up the bulb to transplant. This might be in September or later than September but before your first frost. These articles will help:

After its initial bloom, my Asiatic lily grew quite a lot more buds which got to be about 1-1.5 in. long and 0.5-0.75 in. wide but they never opened. Why is that?
I am not sure why this would be, but one possibility is that the temperature later in the season has not been high enough to promote flower opening. General poor conditions, such as watering or nutrition issues, might also cause this problem. Here is more about Asiatic lilies:

This is my first year with an asiatic lily plant. Now that fall is here, should I cut the current stems? If so, how?
You can let the plant die down naturally, or trim the plant stem down to about 4 to 6 inches in height.

When is the best time to move an Asiatic lily?
The best time is a few weeks before your first autumn frost date. Cut off the stems, dig up the bulbs, and separate them. You can move them to their new spot immediately or store them inside for the winter.
