My daylilies have dying leaves with raised orange and brown spots on them. What can I do to prevent this from happening?
You likely have Daylily Rust (Puccinia hemerocallidis) a new disease that will require removing and destroying infected leaves and spraying the new leaves that come out. We suggest spraying the new leaves that emerge on a 7 to 14 day schedule with two separate fungicides. Start by spraying with Ferti-lome Broad Spectrum Fungicide (Daconil) then the next time that you spray use Ferti-lome Systemic Liquid Fungicide (Banner). This spray schedule should be kept up until the leaves mature and anytime that there is new growth on your Daylilies.
