I'm trying to convince myself this is damage from the last frost we had, but could use some expert eyes. What do you think? This is only showing up on the 2 tallest of my Stargazers.

That's odd... Maybe try removing the affected leaves and see how the rest look?
Where are we going, and why am I in this hand-basket?

Funny, I just did that 5 minutes ago and everything else looks good. Guess I will wait and see what happens. It's possible I sprinkled the area with Preen when the bulbs were just starting to grow and some got down into the tips. Wonder if that would do it?

The first year I used Preen it was very windy and wasn't careful. I do believe I "preened" a few things to death.

It does look like it was caused by something environmental (at least initially) rather that pathogenic. (Meaning not disease or insect caused.) My first thoughts were mechanical damage of some kind, followed by a mild secondary infection of damaged tissue that is of no concern. The Preen venue is a good possibility too.

At any rate, it is not spreading, and seems to be arrested. No worries.

I removed the bad looking leaves after posting above and the rest of the leaves look fine but the buds and flowers have brown discolorations on them, If I remember right these same ones did thi9s last year. Two smaller ones nearby look OK. Wonder if I need to get rid of these bulbs?

Another Oriental in front also has the brown areas on the blooms.

The two photos above do not look diseased to me. It looks environmental, possibly Preen or maybe an insect.

Mine seem to do that too, Susan, especially the orientals. It's usually on the top side of the bud and I've wondered if a drop of rain seepped in and / or then got a little sun burn.

Could be all the rain. I've only noticed it the last 2 years. I haven't applied Preen since long before the buds started forming, so don't think it's that. Guess it could be sunburn, but seems funny that it only happens to the Orietals. Sure ruins the flow=ers. Thanks for your comments.

It looks like burn, have you been hot? We get that a lot since he is always late watering and they are in hot sun, we also get 20 degree or more temps swings within 24 hours which is very hard on them. And it only burns the oriental, the others take the heat better.

I've had hail hit lilies and the spots it hit look like that in time.
