Lynn, is it possible that one lily is sitting in a low lying area, and got quite wet? That's one of the common things that affects lily leaves. It could also be disease, but in your area, where it is quite wet, too much water is often the problem.
We have a very expert lily grower from Oregon, Pardilinum, and I hope she will come over here soon.
Pam, I think the PW program is a waste too. I haven't looked yet to see how much the prices went up. Hopefully not too much. I need some quality time with that catalogue.
