I pulled daffodils out of my lawn early this spring, but couldn't relocate them before their leaves wilted. Should I plant them anyway or wait till fall?

You removed the whole plants, bulbs leaves and flowers? Where have they been since Spring?

In a bucket, sadly. They'd already bloomed, so I pulled the bulbs with attached leaves.

Daffodils as with most bulbs use the leaves after flowering to build up the bulb to flower the next year. The leaves should never be cut off, tied up etc after flowering. They will die down naturally after making food to prepare the bulb for dormancy. It's a good idea to give them some liquid feed while the leaves are still green.

You could try replanting them but be prepared for no flowers next year.

Yes, replant them. Even if they don't bloom next year, at least you've saved them for the future.

Yes, but does it matter whether I plant them now or in the fall?

It doesn't really matter as they will be pretty much dry bulbs. They won't grow until next year if you plant them now.

Alright, I'll plant now so I don't have to think about it later, and hope to at least be surprised by the foliage next year. Thank you!
