Maximum Green & Growth Fertilizer 2.5 Gallon 28-0-0 - Fast Greening

In this review the 2.5 gallon Maximum Green & Growth 28-0-0 liquid lawn food is judged on who needs a fast, heavy-nitrogen boost and whether it delivers noticeable greening. It is best for homeowners or small-scale commercial users who want a concentrated, hose-end compatible fertilizer that mixes quick-release and slow-release nitrogen to correct deficiencies and support thicker turf. The bottom line: this formula is a practical choice when rapid greening and sustained feeding between applications are the main goals.

Key Features

• High nitrogen content: The 28-0-0 ratio supplies a strong nitrogen dose that promotes rapid chlorophyll production and visible greening of grass.
• Dual release formula: With 70% quick-release and 30% slow-release nitrogen, it provides fast correction of deficiencies while maintaining feed between applications.
• Large coverage per container: A single 2.5 gallon container covers up to 32,000 square feet when applied with a hose-end sprayer, reducing refill frequency for larger lawns.
• Broad grass compatibility: Labeled for use on warm and cool season grasses such as Bermuda, Zoysia, St. Augustine, tall and fine fescue, ryegrass, and Kentucky bluegrass.
• Commercial pedigree: Produced in the United States by a company with professional turf experience, which supports consistent product quality and formulation.

Who It's For

This product is aimed at homeowners with medium to large lawns and professionals who need a concentrated, easy-to-apply liquid fertilizer for spring and summer applications. It works well for anyone seeking quick visible greening combined with a follow-up slow-release component to sustain growth.

It is less suitable for gardeners seeking a balanced N-P-K or those who want an all-in-one granular product with added micronutrients; users who prioritize value per ounce should compare cost with alternate spreader-applied fertilizers before committing.

Pros & Cons

Pros

• Produces rapid greenness within days for semi-brown lawns when used as directed.
• Easy to apply with a hose-end sprayer or compatible third-party sprayer, praised for its ease of application.
• Combines quick and slow release nitrogen to support both immediate recovery and continued growth.
• Manufactured in the USA with commercial turf industry experience, indicating solid product quality.

Cons

• Some users feel the product's price reduces perceived value for money compared with other options.
• Does not contain phosphorus or potassium, so it is not a complete nutrient solution for lawns needing balanced feeding.

Our Verdict

The 2.5 gallon Maximum Green & Growth 28-0-0 is a focused high-nitrogen option for users who want swift greening and sustained feeding between applications; it is particularly good for larger lawns and professional use where coverage and ease of application matter. If a balanced N-P-K or lower-cost granular option is required, shoppers should compare alternatives, but for rapid visible results this concentrated liquid performs well.
