Starter Fertilizer 15-20-10 Plus Iron

Lawn Synergy's Professional Starter Fertilizer 15-20-10 is a specialized fertilizer blend designed to support the healthy growth of new lawns, overseeded lawns, and sod. The fertilizer formula has a nutrient ratio of 15-20-10, which means it contains 15% nitrogen, 20% phosphorus, and 10% potassium.

The fertilizer also contains 20% Slow-Release XCU, which is a type of slow-release nitrogen that feeds the grass over a longer period of time. This helps prevent rapid growth spurts and reduces the risk of nitrogen burn, which can damage the grass.

We have included slow-release nitrogen to ensure new seedlings are constantly fed during germination and after for faster establishment.   

In addition to the nutrients and slow-release nitrogen, the fertilizer also contains GreenTRX, which is a proprietary blend of natural and organic ingredients that helps improve soil health and promote strong root growth. This can lead to thicker, healthier, and more resilient grass.  We also added 3.5% Iron and Ammonium Sulfate to really bring out that dark green color you are lookin for.  

Overall, Lawn Synergy's Professional Lawn Fertilizer Starter 15-20-10 is a high-quality fertilizer that provides the essential nutrients and other beneficial ingredients needed to establish a healthy and vibrant lawn that is only available at Lawn Synergy.
