I want to redo my lawn...have been fertilizing and doing a weed& feed application for the last 2 seasons. Still not the lawn I want. I live in VA so a fescue works best. The lawn is all sun...no trees. I want a nice deep green lawn that is weedfree. Should I: Spray with Round up and reseed. or Slit seed it I plan on doing something asap but want the best results. I have the equipment or will rent it...depending on whats the best way to go. Or is there a better way to obtain a plush lawn? Thanks.
