Star Magnolia Tree Leaves Have Become Rusty Brown In Color

Question From: B. hardie - Pennsylvania, United States
Q: My Star Magnolia's leaves have developed a rusty brown color. In the last two weeks Western PA has had over three inches of rain-lucky us? But could this be some kind of fungus and what do I do for it?

A: Rust - a fungal disease will color up the leaves. If it were my tree I would get an onsite inspection from a certified arborist. To find one in your area go to and enter your zip code. Best And Happy Yardening, Nancy
