Problem with Globe Thistle
Thanks for writing. How has your weather been? These plants like well-drained soil, so if your area has experienced more rain than usual, the globe thistles could be having root rot issues. Or a disease may have swept in; if your globe thistles are all growing near each other it's easy for some types of disease to spread rapidly from plant to plant.
