Create a healthy lawn by starting over
Let's get this straight right from the get-go: A healthy lawn doesn't get taken over by weeds. So if it looks like you're raising weeds instead of grass, that's a sign of a more serious problem. And that may mean killing off the grass and starting over. It's a big project that'll take several weekends and may cost you around 25¢ per sq. ft. for equipment rentals, soil conditioners and seed. If you're willing to spend more, you can lay sod instead of planting seed, but don't skip the soil testing and remediation steps.

Evaluate Your Lawn
Going “nuclear” shouldn't be your first option. Instead, start with spot applications of weed killer, dethatching and core aeration. But if you still see more than 60 percent weeds at the start of the next growing season, your lawn is too far gone to save. Your best option is to nuke it and replant.
