I have a question for the applicators out there. Have any of you noticed a difference in quantities of weeds on treated properties that are mulched when compared to collected clipping? The reason I ask is that I have. We are finding weeds in much greater numbers on lawns that are commercially mulch mowed. My theory is that these companies are dropping weed seeds from their mower decks on the turf due to the fact they're using the same equipment to mow untreated turf. Any thoughts?
