Causes

Calla lilies are susceptible to tomato spotted wilt virus, which causes leaf wilt. Lilies also wilt when they need to rest; wilting may mean they require a period of dormancy.

Distinction

If a calla lily's leaves turn yellow and wilt or curl, the plant needs dormancy. White or brown spots and streaks on the leaves indicate the presence of tomato spotted wilt virus.

Treatment

Colorado State University Extension recommends discarding calla lilies infected with tomato spotted wilt virus. If your plant needs a rest period, reduce watering for six weeks to allow it to rest, allowing the soil to dry. When watering resumes, the calla lily should again grow normally.

In bouquets, replace calla lilies with long, elegant flowers. Solid-colored flowers make creating a theme with floral decorations simple and elegant. A white mariposa lily (Calochortus supurbus), for example, is one option for gardeners interested in creating calla lilylike bouquets.
