Camperdown elm #875418

Asked June 30, 2024, 11:10 PM EDT

Leaves curling yellow-brown dry but not falling. Fear of Dutch elm. It’s a magnificent tree and deserves to live! How do I know what it is and what can I do?

Multnomah County Oregon

Expert Response

Thank you for your question, Debra.  There are three diseases that infect elm trees, and a correct diagnosis can be done only by a lab.  I suggest that you send soil and plant material to the OSU Plant Clinic:  https://bpp.oregonstate.edu/how-submit-plant-materials

Good luck!
