That's probably what I used last time.
I'd rather not use it unless it's necessary. I'll keep a close watch out there, spot-checking hostas for rot below the leaf.
Oh I hope it doesn't show up.
I hate even to think of it.
I am hoping someone will post who has experienced frost damage followed by this. And I hope this person says their hostas never suffered from crown rot after that goo appeared on the leaves.
After all, rotting leaves may be normal after frost damage, and may have nothing to do with crown rot. Maybe. No one so far posting here knows.
