Most of the affected plants were new purchases last year and were planted in areas never seen by daylilies before. The one affected last year and this is still in the same spot but seems to be recovering. Some of my seedlings from last year are also affected and are also planted where no daylilies have previously been. This is just my thoughts on this but I really think weather has some part to play as well. We have had a very slow cold spring and only now warming. Some of my lilium have just poked their noses through the soil within the last two days and I usually have buds showing on some of them by now especially the smaller asiatics. Many of my lilium are also twisted and deformed at the growing tip. So could it possibly be a combination of insect and weather?
Glen and Tina I can't really dig, divide and move because a lot of them are still single fan or just barely double fans and I have run out of space for planting.
