They may. Definately move them before they decline further. Be sure to let the foliage turn yellow before digging as they are storing energy for next year. Add some bulb fertilizer to the new area ~~ or bonemeal, or superphosphate.

I agree with the above poster. Move them because they do need the sun. Second year dafs should not need divided but would do better if you give them a little fertilizer to get them going. Mark where they are & in fall give them more fertilizer because in fall they are making the roots for next season.

Probably not next year but the year after. They will need a spring and summer in a sunnier spot to build the bulb up. If you transplant now (while you can still see them!) the leaves will probably wilt and not recover this year.

I had a lot of daffs growing and not blooming under maples. Spent many hours in 2006 digging and moving them and this year got a good show from almost all of them.

leslies,
but it is ok to transplant them now, for exactly the reason you state, but that they may need an extra season to get going again?

thanks, everyone

Wait as long as you can to give the leaves every chance to feed the bulb for next year. But yes, you can transplant them now while you can still find them. If the leaves are not yellowing when you move them, you may or may not get blooms next year, but the bulb will survive and you'll get a show the following year.
