Product Description

The Ultimate Liquid Nitrogen Fertilizer from PetraTools is designed to transform yellow, nitrogen-deficient grass into a lush, thick green. Its ultra-high nitrogen formula promotes rapid growth and green-up. The 28-0-0 Quick & Slow Release Technology provides 70% quick-release nitrogen for immediate results and 30% slow-release nitrogen for sustained growth between applications. This 2-in-1 formula ensures your lawn stays green and healthy with just one easy application.

Versatile and Effective

Whether you have warm- or cold-season grass, this liquid grass food is perfect for achieving consistent growth and a vibrant green lawn. It's ideal for both new and established lawns. To apply, mix 5 oz of liquid nitrogen per gallon of water for maintenance or 10 oz per gallon to correct nitrogen levels. This mixture treats up to 12,800 sq. ft. for maintenance or 6,400 sq. ft. of nitrogen-deficient grass. For best results, use a PetraTools sprayer to evenly distribute the mixture across your lawn.
