PetraTools’ Liquid Iron - Liquid Lawn Solution is an innovative way to restore a true green color back in your grass. Our liquid iron for lawn fights off algae and helps prevent the yellowing of your lawn while adding nutrients. This lawn care solution helps you keep your plants looking their best by increasing the health of their roots and leaves. It’s a sugar-based chelated solution, which means it resists yellowing, unlike many lawn care solutions. Our liquid iron for lawn care is EDTA-free, allowing the solution to penetrate deeply into the ground where it can be used by your plants for nutrition.
