Q. Which contact herbicide do you recommend for lawn weeds this winter? We did not get a preemergent applied in time to control the oxalis, bedstraw, henbit, and chickweed. We have a St. Augustine lawn.
A. One contact herbicide that has worked well for us for broadleaf weeds such as those you have listed is Weed Free Zone. Review the label instructions and make sure it works in a manner that will meet your needs. If not check other products for broadleaf weeds. Make a note on your calendar to apply a preemergent herbicide such as Crew before September 1.
