I have a weed in my lawn each spring that is very low to the ground, deep green with finely divided leaves that resemble parsley. If you step on this weed bare-footed it has little prickles that will hurt your feet when it is stepped on. What is it and how do I control it?
The weed that you have described is known as Spurweed. The best way to control it is to spray Hi-Yield Atrazine on the lawn in late December or early January. One pint of Atrazine will cover 10,900 square feet of lawn.
