Emerald 10-0-20 Lawn Fertilizer

Our 10-0-20 Emerald Lawn Fertilizer with 10% iron and added in GreenTRX is a high-quality, nutrient-rich fertilizer that is perfect for maintaining the health and beauty of your lawn. This fertilizer contains a balanced ratio of nitrogen and potassium, with no phosphorus added, making it ideal for tall fescue lawns, centipede lawns, st. Augustine, and other turf grasses that require a high level of potassium.

In addition to its balanced nutrient content, this specialty fertilizer also contains 10% iron, which is essential for promoting healthy, green growth in your lawn. Iron will give you that dark green color you are looking for. By adding iron to our fertilizer, you can help your lawn stay lush and green all season long without adding excessive growth.

10-0-20 Emerald Lawn Fertilizer is formulated with 45% slow-release technology that ensures a steady and consistent release of nutrients over time. This helps to prevent over-fertilization and reduces the risk of fertilizer burn, making it safe for use on all types of lawns.  This makes for a great stress blend by strengthening the lawn preventing disease and stress.   

Unlike conventional lawn fertilizers, GreenTRX not only feeds the grass, it feeds the soil. Soil is a dynamic habitat that needs nourishment from organic matter. GreenTRX puts organic matter back in the soil, providing a food source for microbes. Healthy soils provide a better foundation for growing grass — in good weather or bad.

Overall, 10-0-20 with 10% iron and GreenTRX is an excellent choice for anyone looking to maintain a healthy and vibrant lawn. With its balanced nutrient content, added iron, and slow-release technology, it's sure to keep your lawn looking its best all season long.

When to apply:

• Tall Fescue Lawns - May-July
• Kentucky Bluegrass - April - Sep
• St. Augustine Lawns - May-December
• Centipede Lawns - March-August

As for centipede lawns, it's best to apply this fertilizer every other month during the growing season, which typically runs from April to September. Centipede grass is a slow-growing grass variety that requires a lighter application of fertilizer and benefits from frequent, smaller doses of nutrients throughout the growing season.  We suggest alternating between the 0-0-4 Nutrigreen and 10-0-20 Emerald for centipede lawns.

By following these application guidelines, you can ensure that your lawn will receive the right amount of nutrients they need to thrive and maintain their lush, green appearance. Remember to always follow the instructions on the label and apply the fertilizer evenly across your lawn for best results.
