Pin Oak Chlorosis
Overview of pin oak chlorosis
Pin Oaks generally do not do well in the typical pH of Iowa soils. To read more about what you can do if you already have a pin oak and would like to help it as much as you can, please read "Pinpointing the Problem with Pin Oaks" and "Pin Oak Problems?")
Type of Sample Needed for Diagnosis and Confirmation
The Iowa State University Plant & Insect Diagnostic Clinic can help you to investigate and confirm if your plant has a disease. Please see our website for current forms, fees, and instructions on collecting and packing samples. Contact information for each states diagnostic laboratory for U.S. residents can be located at the NPDN website. If you have a sample from outside of Iowa, please DO NOT submit it to the Plant & Insect Diagnostic Clinic without contacting us.
