The first ever Lawn Supply Company granular fertilizer delivers on new technologies and unique ingredients! GrowORR G features a 13-0-13 formulation that can be applied to all grass types but works especially well in the midwest region or anywhere soils have a higher pH. We have included the ONLY form of Iron that has been shown in university studies to provide results when applied to the soil. Beyond that we have also included the latest in plant health technologies with peptides and free amino acids for larger root mass and overall plant health in stressful environments. Finally, GrowORR G includes a low salt index (lower burning potential) form of potassium and a form of nitrogen that provides the green you are looking for! Recommended Rate: Apply at 4 pounds per 1000 sq. ft. At recommended bag rate this 45 pound bag will cover roughly 11k sq. ft. Rate can be adjusted according to your nitrogen or potassium application needs. These high quality ingredients are what you expect from Lawn Supply Company products. No exceptions.
