Scotts Green Max Lawn Food With Iron
Scotts Green Max combines fertilizer with iron to promote rapid greening across common grass varieties. The product contains 5% iron, a micronutrient that enhances the greening process, delivering deeper color in as little as three days. It is suitable for spring, summer, or fall use and supports a wide range of grass types. The dual-action formula feeds roots while boosting leaf greening, helping lawns recover from heat or uneven growth.
Scotts Liquid Green Max Lawn Food
Scotts Liquid Green Max provides a liquid, iron-enhanced fertilizer experience for rapid greening. The 2-in-1 formula feeds and supplements with iron to deepen the lawn’s green color. It is designed for use on any grass type and is suited for regular application from early spring through late fall. The liquid format enables quick absorption and even coverage, making it a practical option for last-minute touch-ups before gatherings or outdoor events.
Maximum Green & Growth 28-0-0 (Sprayer)
This Simple Lawn Solutions product includes an attached sprayer and delivers a concentrated 28% nitrogen blend. It covers up to 3,200 square feet when used with the sprayer and emphasizes quick nutrient absorption. A portion of the nitrogen is immediate-release for fast color and growth, while the remainder is slow-release to maintain plant health between applications. It’s suitable for all grass types and is designed to help lawns achieve a denser, greener appearance with regular use.
Maximum Green & Growth 28-0-0 (Liquid, 1 Quart)
This higher-volume Simple Lawn Solutions formula uses a 28-0-0 profile with both quick-release and slow-release nitrogen. It is designed to deliver rapid greening and robust growth across all grass types. The concentrated nature means smaller amounts are needed per application, with a similar goal of maintaining a lush, dense lawn through spring and summer. Regular use supports ongoing color and vigor during peak growing periods.
Scotts Green Max (10,000 sq. ft.)
This larger-format version of Scotts Green Max extends the same dual-action approach—lawn feeding and iron supplementation—for broader areas. The product targets deeper greening within three days and is appropriate for bigger lawns seeking quick color restoration. The iron component supports faster visual results, especially after stress events. Apply per label directions to avoid over-application and ensure even coverage across turf.
Sunday Green Machine Fertilizer
Sunday Green Machine combines nitrogen, seaweed, iron, and potassium in a liquid formula designed to fortify roots and extend the lawn’s green period. It emphasizes fast, even uptake and is positioned for easy application with an included sprayer attachment. The formulation supports improved resilience against common stresses and aims to extend greenness without harsh additives.
Jonathan Green Veri-Green Nitrogen Lawn Fertilizer
Veri-Green combines 29% nitrogen with iron for a quick greening effect and long-lasting color. The fertilizer is designed to feed lawns for up to three months, delivering gradual, steady nutrition that supports a durable, vibrant lawn. It is suitable for all grass types and aims to provide a deep green color within a 7–14 day window, with performance potentially influenced by rainfall and climate conditions.
Buying Guide
- Grass type compatibility: Most products work on common cool-season and warm-season grasses, but always confirm suitability for your turf species before applying.
- Nitrogen form and release: Quick-release nitrogen provides fast greening, while slow-release nitrogen sustains color between applications. A blend can balance immediate results with long-term health.
- Iron supplementation: Products containing iron can deepen greening quickly but avoid overuse, which may cause temporary staining on sidewalks or driveways.
- Application method: Liquid formulas allow rapid absorption and uniform coverage, especially with an attached sprayer. Granular options often require watering after application for activation.
- Seasonality: Spring and early summer are ideal for heavy feeding in many regions, but some lawns benefit from lighter, ongoing feeding through summer and fall to protect against heat stress.
- Area coverage: Choose products that match your yard size or have a scalable application plan to minimize waste and ensure even distribution.
- Environmental considerations: Avoid excessive fertilizer near stormwater drains to protect runoff. Opt for products with balanced nutrient profiles and minimal added salts when possible.
