Title: Ailing non-native red tip photinia
Answered by: Nan Hampton
QUESTION:
My red tips look like they are brittle and the leaves are spotted. What do I do?ANSWER:
Our expertise and focus here at the Lady Bird Johnson Wildflower Center are with plants native to North America. Red Tip Photinia (Photinia x fraseri) is not native to North America but has been used extensively as a landscape plant throughout the South. This plant is especially susceptible to a fungus called entomosporium leaf spot. We have had a similar question regarding an ailing photinia before and I will refer you to the answer to that question.More Non-Natives Questions
