Maximum Green & Growth Fertilizer High Nitrogen 28-0-0
The product uses 28% nitrogen delivered via an attached sprayer, designed for 3,200 square feet. It combines quick-release (70%) and slow-release (30%) nitrogen to support rapid greening and sustained feeding. Best for homeowners who want fast color restoration and strong vegetative growth across all grass types. The sprayer helps ensure accurate application and minimizes waste. A potential limitation is that the attached sprayer may require maintenance and calibration to maintain the correct ratio over time.
Best for: homeowners seeking fast greening with a simple, all-in-one spray solution. Why selected: high nitrogen content paired with a dual-release profile supports both immediate color and longer-lasting feed. Caution: check for any sensitivity to concentrated nitrogen on newly seeded or stressed lawns.
Scotts Liquid Green Max Lawn Food
Contains a nitrogen-rich formula (29-0-0) with added iron for a deep green tint in about three days. It’s designed for quick, simple use with a hose-end sprayer, aiming at up to about 2,000 square feet per 32 fl oz bottle. Best for: homeowners who want a fast, noticeable green-up with minimal effort. Why selected: iron supplementation provides deeper color beyond green hue alone. Caution: iron can stain if mishandled; ensure proper washing after application to avoid residue on sidewalks or driveways.
Best for: quick turnaround and a deep color boost. Choose this if you prefer a ready-to-use hose-end spray and a visible color change within days. Limitation: longer-term feeding may require follow-up treatments to sustain color without over-fertilizing.
Advanced 16-4-8 Balanced NPK – Simple Lawn Solutions
This balanced formula provides 16% nitrogen, 4% phosphorus, and 8% potassium, boosted by seaweed and fish ingredients for better nutrient delivery. It’s designed for easy spraying and is suitable for any grass type, promoting both greening and robust growth. Best for: lawns that need a complete nutrient package without focusing on a single nutrient. Why selected: a balanced NPK profile supports overall turf health, not just color. Caution: avoid applying when the soil is extremely dry or during peak heat to prevent burn risk.
Best for: a well-rounded option that supports long-term lawn vigor. Choose this if you want a complete feeding with premium ingredients and easy application. Limitation: nitrogen concentration is moderate, so rapid color gain may be slower than high-nitrogen formulas.
High Nitrogen Fertilizer for Lawns – TPS NUTRIENTS
Designed to promote lush, green turf with strong vegetative growth, this product emphasizes nitrogen as the primary nutrient. Best for: residential lawns needing a vigorous growth push, particularly in the active growing season. Why selected: high nitrogen focus can deliver noticeable growth and color improvements quickly. Caution: high nitrogen rates should be managed to avoid excessive shoot growth when not balanced with potassium.
Best for: those seeking a straightforward nitrogen boost for rapid turf development. Choose this if you want a simple, high-nitrogen option. Limitation: not a complete macro-nutrient package; consider pairing with a broader feeder if potassium or micronutrients are needed.
Commercial Grade Lawn Fertilizer with Iron – Simple Lawn Solutions
This liquid booster includes iron and nitrogen, designed as a ready-to-use hose-end sprayer covering up to 3,200 square feet. With 6% nitrogen, it aims to darken greens while supporting growth. Best for: homeowners who want both a color boost and more aggressive growth in a single spray. Why selected: iron helps deepen the green tone beyond sheer nitrogen effects. Caution: excess iron can cause temporary staining on surfaces if misapplied.
Best for: a lawn energizer that darkens color quickly. Choose this if you want the combined effect of iron-driven greening and easy hose-end application. Limitation: iron concentration may not address potassium or phosphorus needs for broader plant health.
Buying Guide
What form best fits your lawn care routine?
Liquid fertilizers offer quick results and uniform coverage, ideal for busy schedules or newly established lawns. Granular or slow-release formulas provide longer-term feeding with fewer applications. For large lawns, a ready-to-spray hose-end option can reduce setup time, while sprayer-attached products help ensure precise dilution and even distribution.
How important is nitrogen type and release?
High-nitrogen liquids can deliver rapid greening, but consider the release pattern. Fast-release nitrogen produces quick color, while slow-release formats sustain growth over weeks. A combination of both can balance immediate benefits with longer-term turf health.
What about nutrients beyond nitrogen?
NPK blends (nitrogen, phosphorus, potassium) support root development, leaf health, and overall vigor. Some formulas include iron for deeper greening, while others emphasize micronutrients. Match the blend to your lawn’s needs and soil test results when possible.
How much area will you treat and how often?
Check product coverage and spray efficiency. For large areas, select products with sprayers or ready-to-apply bottles that cover thousands of square feet per treatment. Frequency depends on product type, lawn condition, and seasonal growth cycles.
Any cautions to consider?
Avoid applying concentrated formulas on stressed or newly seeded lawns. Use proper dilution, follow label directions, and water in after application if recommended. Iron-rich products can stain concrete and siding if not handled carefully.

Frequently Asked Questions
- What is the main benefit of a high-nitrogen lawn fertilizer?
It promotes lush green color and dense growth by supporting leaf and blade development. - Should I use liquid or granular fertilizer first?
Start with liquid for rapid greening or when establishing a maintenance routine; use granular for longer-term feeding and less frequent applications. - Can I mix multiple fertilizers?
It’s generally not recommended to mix products. Use one product per application to avoid nutrient imbalances and potential burn. - How often should I fertilize my lawn?
Follow the product label’s cycle, typically every 6-8 weeks during the growing season, adjusting for climate and soil health. - Is iron in fertilizer necessary?
Iron accelerates greening but isn’t a substitute for nitrogen or potassium. Use iron-containing formulas to enhance color as needed. - What should I consider if my lawn is stressed or drought-prone?
Apply nutrients only when the lawn has adequate moisture and avoid high-nitrogen applications during heat waves or droughts.
