Why customers choose PatioZora Garden

PetraMax Liquid Lawn Fertilizer is a ready-to-use concentrate designed to feed grass with essential nutrients while promoting a robust root system. The 16-4-8 NPK blend delivers a rich green color, improved density, and resilience across common lawn grasses, thanks to high-purity humates and supplementary potassium.

What sets PetraMax apart is its balanced nutrient mix paired with a smart nitrogen delivery system. The product supports both rapid greening and sustained growth, helping your lawn look vibrant after each treatment without harsh shocks to the soil.

Two-in-one nitrogen delivery for steady growth

The fertilizer provides quick-release nitrogen for rapid green-up and slow-release nitrogen for ongoing growth between applications. This combination helps maintain a more even color and healthier turf over time.

  • Balanced NPK 16-4-8 supports color, root development, and temperature tolerance across grass types.
  • Humates and potassium encourage deeper roots and overall soil vitality.

Effortless application that fits a busy season

Mixing is simple: 5 oz per gallon of water for maintenance or 10 oz per gallon for deficient lawns. When paired with a PetraTools sprayer, the mixture distributes evenly over large areas, saving time during spring and summer care.

  • Treats up to 25,600 sq ft for maintenance or 12,800 sq ft for NPK-deficient lawns.
  • Apply every 14 days for best results, aligning with common lawn care cycles in warm seasons.
