Shasta Daisy Stems Are Brown Below Flower Heads And Heads Drop

Question From: Duluth, Georgia, United States
Q: About 4 " down from full-bloomed head of Shasta daisy appears to be brown, as something may have sucked it dry. Heads drop down like broken. Rest of plant is healthy. Can't locate any insect or slug. Any idea what did this?

A: My guess is you have some sort of vascular disease. Cut back the infected stems to the base of the plant and run the plant on the dry side. If it continues, take samples into your independent garden center that sells these plants for a more accurate ID. Best And Happy Yardening, Nancy
