Here are some photos of my neighbor's yard where he had a big tree taken out. I offered to seed it if I could do a few tests to see what would work the best. Sorry--the upload failed for the earliest--the September 30 photo. I used Scotts "Classic" which is about 30 percent improved perennial rye. The best 2 foot wide strip was 12 pounds seed per thousand or about 4 times the usual rate, along with double fertilizer. 26-0-6. Very dry when seeded, but rains began in early October. Not irrigated. In the December pic I had seeded over the whole area and fertilized the entire left half of the lawn. The right half was fertilized about 30 days later.
