They are now sprouting up in the Midwest. Poison ivy too. Right now is our "vegetation killer time" -- non-turf especially, but calls are coming in for killing volunteer trees in turf areas too. . How do you guys handle this? "Brush killer that does not harm turf" or what? How much do you charge? By the minute or by usage or what? We charge $2.00 per minute. We use "brush killer" plus spreader/sticker which does not harm turfgrass. It kills poison ivy & vounteer trees too without harming turf. Thanks.
