On a recent stewardship visit on one of the St Louis Butterly Byway Project sites, our team decided the ragweed among others needed to be mowed in a classic height control mowing event. We often encounter excess weed chaff or seeds in our equipment radiators at the end of a mowing event. On some occasions, the pollen cycle is at its peak. Fortunately, neither of our team members suffer from severe hayfever. So keep this in mind, the radiator is black. Holy Pollen Folks!
