Well it finally happened to me. I burned a lawn with fertilizer and liquid weed control, definitely not something to be proud of and it is quite embarrassing. Here's the details: pulled up to the lawn and it was looking a little stressed and dry but definitely not dormant nor was it brown. I decided I would do my app since we had significant rain in the forecast. I applied 18-0-8 with grub control 40% coated at a rate of .75lb N per 1000. I also spot sprayed for broad leafs throughout the lawn and blanket sprayed the perimeter (since it boarders a weedy field). Received all call today that the lawn was burnt is some areas and really brown/burnt where the wheels of my permagreen drove over the lawn. What gives? We did have a good amount of rain on days 2&3 after my app. None of my other lawns have had any issues? Any thoughts why this might have happened?
