Pink daffodils?

I have a friend who bought pink daffodils, but they only came up pink the first year that she had them. I was wondering if there is something that she can add to the soil to help the pink color come back.



Thanks.

Hmm - they may want more sun or less sun. Alternately, she can divide them and give acid-based fertilizer to one group and some lime for the other. Another factor could be aluminum, which changes the color for hydrangeas. If they were pink because they starved them for something that is normally found in the soil, you will not be able to replicate that. But I would also ask brent and becky's bulbs below if they have heard of this - they know bulbs so they might know what the problem is.
