The Stone Barns Center for Food and Agriculture in upstate New York is on a mission to improve how America farms and eats. To support its nonprofit farm and education programs, Stone Barns creates this premium mulch from all-natural materials, taking great care to ensure each batch is rich with the positive microbes that nourish healthy, fertile soil. Helps to restore the beneficial fungal and bacterial organisms that chemical and salt-based fertilizers can strip from soil. Encourages the natural ability of plants to resist insects and disease. Helps soil and plants retain moisture so you can water less. Suppresses weed growth naturally, without harsh chemicals. Made from all-natural materials, including two parts triple-ground mixed hardwoods and one part Stone Barns premium compost. All ingredients come from known sources-never from municipal dumping sites, unlike the materials used in most commercial compost and mulch. 32 qt., 32-34 lb. (will cover 7 sq. ft. at a depth of 2").
