I received this summer some beautiful Tiger Lilies. They are my first
lilies and I don't know how to care for them very well. I have had 3 or
4 baby lilies and thought they were doing ok but recently one of the
big lilies went yellowish and then died! I replanted them in separate
pots and now I am waiting breathless to see what happens. Some are
showing a bit yellowish. Can anyone give some advice?

Thanks and sorry for the newbie question.
