    Two of my daylilies have yellow dots on all the leaves. They are in close proximity to one another, & no other daylilies on the property have this condition. I am concerned about a contagious virus. Does anyone know anything about this?

    Ohhhh!! Dots not good! It looks like Daylily Rust. This is too close to home, eek!! Check this Cornell University web site for more info on Puccinia hemerocallidis. http://plantclinic.cornell.edu/factshee ... lyrust.pdf I will check all my daylilies. A task that I have now made longer. It looks like it is on a Catherine Woodbery......which is not on their susceptible list.

    Double eek!! I have it on three daylilies, Catherine Woodbery, Rosy Returns and one other(too dark to tell which one).

    More tomorrow,

    Jerry

    Jerry---Oh my, tell me it ain't so! I remember hearing something about daylily rust & when I examined the plants today, I did not see any pustules poking out of the surface on the underside of the leaf. I will look more carefully tomorrow in the daylight.
