Is it too much rain or a virus that stunts the flowers and causes them to yellow before blooming with brown streaks on the petals? I have orientals and orienpets and asiatics.
Could it be the lack of an essential nutrient that causes this? I have only daylilies, but I find that if a patch isn't doing well, fertilizing that patch restores it to health.
What do the Tiger Lilies like? Super Phosphate, Holly Tone, ??
My neighbor said his lily blossoms were dropping before blossoming. I have not seen that before. My lilies are doing wonderfully this year.
