Petra Petramax Liquid Nitrogen Fertilizer 28-0-0

Petra Petramax is a high-nitrogen liquid lawn booster designed to help your turf look greener and healthier. The 28-0-0 formulation focuses on providing nitrogen when your grass needs it most, enabling richer color and stronger growth with a spray-on delivery that’s easy to apply. While results depend on local conditions, many users notice faster greening after a treatment, especially in spring and early summer.

In practice, this liquid fertilizer is designed for uniform coverage with a compatible sprayer, helping you avoid patchy spots and uneven color. It’s a practical option for those seeking a straightforward way to refresh tired lawns without complex mixing or multiple steps.

Two-in-one release for balanced nourishment

The formula combines two nitrogen-release profiles to support both immediate impact and long-term feeding:

  • 70% quick-release nitrogen for rapid green-up and visible growth
  • 30% slow-release nitrogen for ongoing nourishment between applications

Versatile for all grasses and lawn ages

Designed to work with warm-season and cool-season grasses, Petra Petramax is suitable for new lawns taking root as well as established turf seeking rejuvenation. It’s a flexible option when you want a single product that adapts to different lawn needs.

Simple mixing, precise application, wide coverage

Application is straightforward and designed to minimize guesswork. For routine maintenance, mix 5 oz of product per gallon of water. For a stronger corrective boost, use 10 oz per gallon. When sprayed evenly with a PetraTools sprayer, you can expect broad, uniform coverage across your lawn.

  • Mix 5 oz per gallon for maintenance
  • Mix 10 oz per gallon for nitrogen-deficient lawns
  • Treats up to 25,600 sq ft for maintenance or 12,800 sq ft for correction
  • Best results come from even spray across the lawn surface

USA-based support and a trusted family business

PetraTools is an American family-owned company, proudly based in Carlisle, Pennsylvania. The brand backs its products with a satisfaction guarantee and responsive USA-based support to help with questions or setup as you care for your lawn.
