My lawn is a real mess. The front was sodded a year ago (new construction), and it's really thin and has weed due to neglect and inexperience.The backyard is just dirt, and weed. Mostly dirt. I am hoping to hire a lawn service to help me overseed next month. After overseeding, hopefully the grass will start growing and I can do the fertilizing and mowing. Is over seeding only too small a job for lawn service company to consider? My lawn is about 5300 sq. feet (front + side + back). I can afford to pay hundreds but not thousands. Is it realistic? I'm a first time homeowner and never have to take care of lawn before. Thanks!
