Total Lawn Renovation: Killing Weeds, Soil Prep, and Seed Selection for Clay Soil

For a 200×150 ft weedy lawn on Ohio clay, the best approach: kill existing vegetation (glyphosate), remove debris, import screened topsoil, blend with compost and peat, grade for drainage, then seed with a tall fescue blend (drought-tolerant, disease-resistant). Sod is instant but costly. If a lake is available for irrigation, design a pump system. Rototilling alone won't fix deep compaction; professional grading ensures long-term success.
