Weed Treatment - Knowledgebase Question

I live in Oklahoma City and have mostly Burmuda grass. In the spring I would like to overseed with Fescue. Before I do that I would like to treat my lawn with a pre and post emergent to kill the weeds. What product do you recommend?

Fescue should be sown in the fall if you plan to use a pre emergent on your lawn in late winter or early spring. Otherwise the pre emergent will stop the grass seeds from germinating. If you want to seed this spring, forego the pre emergent. Once the new grass is up and growing and has been mowed 3 times it will be established enough to tolerate post emergence weed killers. You could then use a weed and feed product. If you hold off on overseeding your lawn until fall, you can apply a pre emergent now to keep weed seeds from sprouting. You may not need to apply a post emergent if you stop those weed seeds from germinating now. Best wishes with your lawn!
