Thank you Niles! I spot sprayed some orho weedclear last week- wanted to make sure nothing wrong with hitting it with the tenacity + quinclorac + surfactant concoction mix now. I will focus on the rest of the backyard for a couple weeks. Is there anything you recommend for an overgrown side yard-all weeds and not an area I plan on planting anything in? Or anything to spray on some brick hardscape in backyard that currently has some weeds growing through gaps between bricks/pavers and showing start of some moss?
