Customer Reviews
The grass stood to attention with his big bad boy!
Love this product
I dont waste my money buying other products that dont work like this does
Love it
great service
I bought Trojan Lawn Fertilizer because the box promised “maximum protection and powerful performance.” For grass. Totally normal.
Within a week, my lawn was thicker, fuller, and standing at attention. The blades are strong, resilient, and clearly overachieving. The package says it creates a “protective barrier” and “ensures long-lasting coverage,” which feels like a lot of confidence for turf.
Side effects include:
Rapid expansion in all the right areas
Neighbors asking what I’ve been using
A yard that now believes in safe, responsible growth
Final verdict: If you want your lawn lush, bold, and practicing safe spread, Trojan delivers. Just remember — always apply responsibly.
