Used in establishing new lawns, PennMulch is an excellent alternative to conventional "seed protection" methods like straw. Penn Mulch pellets are made of recycled paper that breaks down naturally without robbing the soil of nutrients. PennMulch serves as a two in one starter fertilizer and straw. After seeding, spread the PennMulch, water it and watch it grow! The pellets will expand, providing protective cover for your seed from pests and harsh sunlight, while retaining the valuable moisture essential to seed germination. Sold in 50ld bags. One bag covers approx. 750 sq. ft.
