My mint looks diseased. See picture. Can I cure it or should I pull it out?

Thank you for your question. Your plant is infected with a fungus called ‘rust,’ described here: There are no chemicals approved for homeowners. The only control available (and whether it is effective is unknown) is Serenade MAX. Since this fungus is nearly impossible to control, and can infect the roots, you might want to consider destroying the plant, and acquiring a variety that is resistant to the disease. Those alternatives are mentioned in the article. Good luck!
