I have a customer who seeded one part of his lawn. He put down several bags of top soil, compost, and manure. Turned over the existing soil. First he put down rye mix Lesco seed (he said he bought it at Home depot) it dies and then he bought a blend from Lesco and it is barely surviving. They both started out nice. It's a mostly shaded area. He says he didn't over water. Any clues?
