You might be a little early for flowers. Check between the leaves toward the base and see if there are any buds forming near ground level.

If you had to plant late - November/December - then it could well be mid-June before you see results.

(If nothing's happened by July - sigh, put it down to experience, and leave them alone for next year. They're usually indomitable bulbs.)

Oh thanks, vetivert8
I would have moved them.
I'd rather wait and see if they bloom.

Is this the same for my daffodils?
Although many of them did bloom some didn't
in a certain area only.

Thanks, CDO
