i met a guy, who has worked on a golf course for many years. this is what he said to me:" i have never done residential work, but if i did, my lawns would be done like this- seeding with 70% blue grass, 30% rye. fert programs would be- 4 aplications throughout season of 0-0-15. the potasium is all he wants. then, in the fall, sept, oct, november each recieve an aplication of 25-10-10 with 2% iron. one pre emergent in the spring, liquid containing no fert. insect and weed treatments strictly on an "as needed" basis." does anyone agree with this program?
