Soil Testing

A soil test is the only way to determine what nutrients are available in your soil. While you can find soil testing kits at stores or online, these are often not accurate. When you get your soil test results, recommendations are made for amendments to improve the soil based on what you are going to be growing.

The University of Wisconsin-Madison Plant Disease Diagnostics Clinic (PDDC) provides assistance in identifying plant diseases and provides educational information on plant diseases and their control. Many times, for a diagnosis to be made, a sample (photographic and physical) will be needed. You can contact Julie Hill, Horticulture Outreach Specialist at for guidance and information.
