I just had my back yard hydroseeded 15000 sq feet. They are a repultable company and used Lesco's Field & Athletic seed mix with starter fert and wood mulch. I have full sun in NJ. I prepped the soil with a rock box and have 6 above ground sprinklers that cover the entire yard. I am keeping the wood mulch moist and water in the morning and evenings. Now, my question: How long untill the seed starts growing and will there be spotty areas?
