I would get a sample in to the MSU Diagnostic Lab in East Lansing to get their opinion on what is causing the stunted foliage and white leaves. This is unusual and I cannot provide an explanation for this. Please go to the following site for the MSU Diagnostic Services for their contact info, how to submit a sample, cost of submittal and their mailing address. https://pestid.msu.edu/

Hello Robert,

Thank you for your response. We will collect a sample and send it in. I want to share some photos with you and I've included them.

We've never seen anything like this. It's like the chlorophyll has been removed.

Are there any other plants nearby that are also white? I have seen a herbicide used in a field drift on to nearby trees and turn them white,
