How to fix a lawn that is mostly weeds?

Fixing a lawn that is mostly weeds usually requires a step-by-step makeover rather than one quick treatment. Many homeowners start with a full-season weed control program to knock back the existing weed population using selective herbicides. Once weeds are under control, the next steps are improving the soil with aeration, adjusting mowing height, and adding the right fertilizer to encourage thick, healthy grass. In some cases, especially in Oklahoma’s tough soils, overseeding or even partial renovation is recommended to introduce better turf varieties. Consistent maintenance and follow-up weed control are essential; otherwise, the empty spaces left by dead weeds will simply refill with new ones.
