How Much Miracle-Gro Should I Use for Tomatoes?

Tomato plants are hungry vines, gobbling up high levels of both water and soil-borne nutrients to support foliage growth and fruit production. For the biggest tomato yield, supply each plant with regular fertilization. When it comes to picking a fertilizer, Miracle-Gro products come recommended by horticulturist Ron Smith, who says brands like Miracle-Gro will "improve growth and fruit set" in your backyard tomato garden. The exact amount of Miracle-Gro you need varies depending on the product you use.
