Sad day today. I have aster yellows disease in my herb garden. I’m having to dig up half my herbs to throw away. The Iowa state university lab says the infected herbs are not harmful to people so I’m not sure if medicinally if there is anything good to them yet before I trash it all. I have to start over so many plants that have been established for 4-5 years. I wish I realized this disease last year but I assumed what I was seeing on the plants was brown spots from drout and high Temps 🙁
