15-0-15 Fertilizer with Iron

A 15-0-15 with iron fertilizer is used to promote lush, green growth in lawns and turf (especially Centipede, Bermuda, Fescue, St. Augustine) by supplying nitrogen for foliage, potassium for vigor, and iron for deep green color, while being phosphorus-free for areas with phosphate restrictions. It's excellent for improving plant hardiness, correcting nutrient deficiencies (N & K), and preventing yellowing, typically applied in spring and fall.
