Spider Lily (Lycoris radiata) not producing blooms

I planted five spider lily (lycoris radiata) bulbs during the summer of 2006 in my front flower bed. When I bought them, the nurseryman said they might not bloom the first year because it was so dry, but it should bloom the second year. Well, this was the second year and I never got any blooms. They have produced foliage both years, just no flowers. Any ideas on why they would not bloom? Any ideas on how to get them to bloom next year?

I planted about 50 this spring and they didn't bloom either. I just assumed it was because of our sever, record breaking, drought. Only about 2/3 of them even put up foliage.
Hope someone sends good news.

In my experience, Spider Lilies take a while to poduce blooms (2-3 years), and are very finicky about being moved.... they don't like it! However, the wait will be worth it, because they are gorgeous when they decide to show thier stuff!

I agree with ggrevas; and L radiata seems to take the longest to settle in for me. If you must move any of them, September seems to be the best month. They all like wet winters but dry during mid to late summer. Lycoris traubii transplants and blooms the next fall for me--if I can move them during September-mid October.

Thanks!

Thanks for the thoughts. Do you know if they divide at all? If they do, I guess it would not be nearly as often as daffodils or iris, if they take 2 or 3 years to produce blooms.

Lycoris traubii offsets really quickly for me, the Lycoris radiata offsets slower. Often they will offset even if its a poor year for blooming--seems to be no relationship between blooming and offsetting for me. Lycoris radiata is just a slower grower, bloomer, and offsetter for me. They may not like their location but they are close the the Lycoris traubii, so I'm not inclined to move them, since the Lycoris traubii do so well in that location.

We don't divide ours and they do just fine. I think it depends on how many blooms you want. I've dug up clumps that had twice as many bulbs as there were blooms. So I think that when crowded they won't bloom as much but if you divide them you have to wait an extra year for the blooms.

I've had blooms in the same year before (we have 100's) and the only thing I think I did differently than usual was that I immediatly put them in the ground after digging. Also I did not plant them very deep that year because the soil was so rocky (which could be another reason they bloomed).
