What is the accepted industry rate - if there is such a thing - for the amount of seed needed when overseeding a property? Mine is approximately 10,000 sq. feet. The back of a 10 lb bag of seed I bought said that would overseed 7,000 sq. feet, yet someone in the biz once told me you need about 3 lbs of seed for every 1,000 sq. feet. Can anyone clarify? Thanks.
