I will be renovating my lawn because it is all weeds (new construction). I haven't applyed Round Up. I plan to just either till the top of the soil a couple of inches deep to break up the soil and pulverize the weeds or power rake/vertical mow the weeds, rake the weed material and re power rake/vertical mow to lightly break up the soil before I put the starter fertilizer and seed down. What do you guys think. I live in easst central Illinois, so now is the ideal time to do this.
