re: Battling Oxalis Weeds

I just sprayed my front and backyards last week. I had oxalis everywhere. I used Weed Free Zone and Atrazine. Within 2 days most of it was shriveled and dead. I also did a second application about 3-4 days later since it appeared that I must have missed some areas because they were still green. I used a 1 gallon pump sprayer and mixed about 4.5 ounces of Atrazine and a little less that 2 ounces of Weed Free Zone. I'm also on the south shore.
