Guys, This year my lawn has developed a weed problem. I've attached a few pics so you can take a look and maybe help me out . The lawn has not been fertilized in a long time and I'm thinking this is why the weeds are over populating the grass. What is the best way to take care of this?? I continue to plug these things out but they keep on coming back. Should I spray some sort of Weed B Gone first and fertilize the yard?? Anything would help! Thanks!
