In the Pacific Northwest, your lawn must withstand cool, wet weather all year. Pennington Smart Seed Pacific Northwest Mix consists of a premium mix of Perennial Ryegrass and Fine Fescues that are specifically designed to flourish in this climate. In areas of your lawn that receive 4 to 6 hours of sun daily, plant this grass seed mix in the early spring or early fall and see results in 8 to 14 days. A 3-pound bag covers up to 750 square feet for overseeding an existing lawn and 250 square feet for starting a new lawn from scratch. What makes Smart Seed smart?
