## Description

desertcart.com : PetraMax Liquid Lawn Fertilizer for Lawns Concentrate - Liquid Fertilizer for Lawns, Food for Grass - 16-4-8 High Nitrogen Lush Green Grass, Phosphorus for Strong Roots - Apply Spring & Summer (1 Gal) : Patio, Lawn & Garden

Review: Lush green Florida lawn. - It Works out pretty good, it gave the lawn the look that I had envision, wonderful product.
Review: Pleased with results! - Used on newly planted grass and existing lawn. New grass is coming in thick even with a lot of heat. Existing grass is greener then any of the neighbors which is amazing considering the heat and lack of rain. I may re-apply in 4-6 weeks depending on conditions. I think the healthier lawn is helping reduce weeds also. Still new to product but pleased so far!

### ⭐⭐⭐⭐⭐ Lush green Florida lawn.
*by G***N on June 6, 2025*

### ⭐⭐⭐⭐⭐ Pleased with results!
*by R***B on July 14, 2023*

### ⭐⭐⭐⭐ Flake particulates in fertilizer
*by K***R on May 27, 2022*

This product really works great; however, I typically need to filter the product because the flakes clog my hose end sprayer. There must be a solution for this issue. I have purchased different sizes of this product; however, the flakes are in all of the products. I'm thinking that the flake issue cannot be resolved, because it is part of the makeup of the product, similar to the flakes that appear in my stored tap water.
