Will rust kill a daylily?

Rust does not normally kill the daylily but it does affect how the plant looks in the garden and can spread to other plants. Rusty colored postules appear on the underside of leaves. This is how you can tell the difference between rust and a similar fungal disease called daylily leaf streak.

What’s wrong with my daylilies?

A fungal pathogen that attacks daylilies. Daylily rust is caused by the fungus Puccinia hemerocallidis and affects the leaves and scapes. It is not a new disease of daylilies, having been reported previously in China, Taiwan, Korea, Japan and Russia (Sakhalin, Kuriles and Siberia*).

How do daylily spores travel from one plant to another?

Instead, these new spores must be transported by the wind or other means to a plant of the alternate host, Patrinia, which is a perennial plant also of Asian origin. After completing the next stage of the life cycle on a Patrinia plant, the rust can then pass back to daylilies.

How do you prune daylilies after they bloom?

On receipt of new daylilies, some growers are peeling the outer layers of leaves from new plants right to the crown, and then cutting the remainder about one to two inches above the crown. The plant may then be soaked in fungicide if desired.
