Lily leaves turned white after planting
 

Planted 5 White Bressingham African Lillies yesterday and today the last 3
to 4 inches of the leaves have turned white and droopy. I had topdressed
this bed with topsoil and pine mulch in spring, but there was still a bit of
decaying old pine straw in the bed left from a year or two ago. Otherwise,
it is strictly zone 7 clay underneath.

I'm guessing the pine has something to do with this? Should I pull them out
tonight, clip the dead ends and replant in just topsoil?

The dozen Stella D'Oro daylillies I planted with them still look happy for
the moment.
