Question
Two years ago I separated my lillies and now they don't bloom.  What can I do?

Answer
Hello Pat

When you replanted your divided plants did you enrich the soil with compost?  Daylilies do like a rich soil and also like to be in full sun.

I suspect that you need to give your plants a regular feed with a liquid fertilizer.  

If they are in the shade you might consider moving them to a sunnier spot.  

If they flowered well before you divided them, there is no reason why they shouldn't do so again.
