Answer: There are several ways to remove existing lawn/weeds. You can treat the area with a herbicide containing glyphosate -- read and carefully follow all of the label directions. You can remove it by stripping it off with a rented sod cutter machine. You can dig it out by hand. You could also smother it by covering with a thick leayer of newspaper topped with organic mulch for several months. Before planting you will want to loosen the soil down about a foot and probably will need to add a generous amount of organic matter such as compost. (If you used the paper and mulch, you can turn these and the dead grass right under into the soil without removing any thing.) You should also run some soil tests to check fertility and soil pH levels, then add fertilizer and/or lime as indicated by the test results at the same time. I hope this gives you some ideas.
