I have never overseeded a property this large. Does this seem reasonable. The purpose of the overseeding is to have a green yard during the winter months. I measured the turf areas at 33,000 +/- sq. ft I am applying seed using a slit seeder at a rate of 10# per 1000 I will also spread starter fert I am charging 360.00 for 300 lbs of perennial rye seed. Starter fert will be 40.00 Slit seeder rental 75.00 5 hrs labor 200.00 Total $675.00 I will mow the turf as low as I can. Then begin slit seeding in two directions followed by an application of starter fert. I will then irrigate daily, once in the AM and once in the PM as local regulations allow. In the past I have always just broadcast my seed over low cut bermuda and then repeated the broadcast in two to three weeks in areas that looked thin to get a full looking yard. I do not know about broadcasting over the Zoisia and since this is a high end model home for a builder I want it to come in full on first try which is why I am using the slit seeder. Comments would be welcome.
