Quarantines, In-State and Import Restrictions for Plant Material

​​​​​​​​​​​​​​​​​Wisconsin has plant protection regulations in place to help prevent introducing plant pests and diseases into the state or spreading them within the state. In general, nursery stock arriving in Wisconsin must have certification from plant health authorities in the originating state that it is apparently pest-free. ​We also have restrictions on plant material from some states, as noted below. Importing invasive plant species is generally prohibited, but may be allowed by permit under some circumstances.​ ​If you are moving or handling any of the affected materials from the areas indicated, you can find details about the requirements and contact information in this document:
