The formula uses 30% slow release nitrogen to deliver a steady nutrient supply without surge growth. A well-balanced nutrient ratio supports turf protection through cold weather stress. Added humates promote root cell development, while 4% iron and 3% sulfur contribute to a deep, sustained green color. This product is applied by lawn care professionals and knowledgeable property managers as part of a late-season turf maintenance program.\u003c\/p\u003e\u003cp\u003eThis fertilizer is suited for residential and commercial turf applications during the fall and early winter feeding window. It is particularly effective when used in conjunction with fall overseeding programs, as it supports new seedling root establishment alongside existing turf. The slow release nitrogen component reduces leaching risk in cooler, wetter soil conditions typical of late-season applications. Coverage is rated for up to 5,000 square feet per bag.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e30% slow release nitrogen for extended, steady feeding through fall and winter\u003c\/li\u003e\n\u003cli\u003eIron and sulfur content promotes deep green color without excess top growth\u003c\/li\u003e\n\u003cli\u003eHumate additives support root development and nutrient uptake\u003c\/li\u003e\n\u003cli\u003eStores nutrients in root zone for early spring green-up\u003c\/li\u003e\n\u003cli\u003eIdeal for use alongside fall seeding programs\u003c\/li\u003e\n\u003cli\u003eCovers up to 5,000 square feet per bag\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on cool- and warm-season turf grasses in residential and commercial lawn applications as a fall and winter fertilizer treatment.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eApply with a broadcast or drop spreader calibrated to the bag coverage rate for uniform distribution.
