For Iowa
All non winter hardy or annual plants do not require inspection or license to sell in Iowa if grown in Iowa. All winter hardy plants(anything that above ground growth survives) has to have a license to sell in Iowa. So essentially figs grown and sold in Iowa don’t require anything to sell, but I get the license to sell interstate which all states require something like a license/permit to import. Cost $30 per acre inspected per year, inspector comes, looks things over closely, checks for anything invasive, disease or whatever else may be an issue. Once done gives the state a go ahead to process a license. Inspection takes 30 minutes or less but the staff are very helpful and open to all lines of communication to help you grow better. I’ve text them for Alaska, California, and Arizona requirements and they do the legwork deciphering the laws to make sure I’m 100% legal shipping there.
One year I bought a plant with spider mites which ran through all figs right at moving trees outdoors in spring. I brought up the mites and they looked them over closely, made a note on my license and gave me a good list of chemicals to take care of it. Did not affect my license but must be marked on there so commercial buyers can see it when looking up a license.
