In Pennsylvania, your lawn must withstand cold winters and hot, humid summers. Pennington Smart Seed Pennsylvania Mix consists of a premium mix of Kentucky Bluegrass, Perennial Ryegrass, and Fine Fescues that are specifically designed to flourish in this climate. Smart Seed Pennsylvania grass seed mix is disease-resistant and drought-tolerant and contains just the right amount of fertilizer to help your lawn succeed. 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 1,000 square feet for overseeding an existing lawn and 330 square feet for starting a new lawn from scratch. What makes Smart Seed smart?
