Research has shown that using sulfur, iron, and zinc on a well-fertilized lawn can reduce the amount of nitrogen needed to maintain green grass by 10 to 15 percent. And even though this is a lawn fertilizer, it can also be used on gardens, trees, shrubs, and flower beds. $23 per 40 lb. bag--Price includes tax and fee for credit card use
