Hello,

You can get a confirmed diagnosis of the problems with your Magnolia tree from the MSU Diagnostic Plant Lab

MSU Plant & Pest Diagnostics is no longer accepting walk-in consultations at this time. They are open for business for all samples that are dropped off or mailed to the lab. When submitting plant samples, they encourage clients to email digital images to accompany the physical samples. Images can be sent to <personal data hidden>.

From the lab: Please do not ship samples on Fridays. Due to the current COVID-19 circumstances, please allow additional processing time. They thank you for your patience and understanding.

There is a $20-25 dollar fee (if they need a sample sent). I am guessing that the lab will probably want a sample to look at under the microscope

Every sample must be accompanied by a completed submission form. Please place the form in a separate resealable bag to prevent it from getting damp or soiled.

The form is at this link:

Complete details of submitting a sample are at this link: https://www.canr.msu.edu/pestid/submit-samples/

ANOTHER OPTION WOULD BE TO FIND AN ARBORIST AND GET AN ONSITE HEALTH ANALYSIS OF THE MAGNOLIA TREE

Hope this helps!!



You are welcome - Have a great day!!
