Umbrella Magnolia Leaves Have Large Pale Yellow Patches

Question From: Oradell, New Jersey, United States
Q: Umbrella MAGNOLIA leaves are showing large pale yellow patches for the 2nd year, but the white blooms are plentiful

A: Sounds like a fungal disease. Take samples of leaves to a good independent garden center or nursery that sells these trees for a more accurate ID and control. Better yet get and onsite inspection from a certified arborist. and enter your zip code. Best And Happy Yardening, Nancy
