I'm hoping to aereate and overseed this weekend. Yard is approx 30,000 ft2. I was hoping to rent the aerator after work on Friday. How long should it take me (since I've never used it before). I'd have about 3 hours of daylight after I got home, is that enough time? I'm supposed be picking up 60 bags of compost Saturday AM to spread over the entire yard. Another question, should I spread the seed then the compost or vise versa?
