Combines ironRoots plus mycorrhiza with soluble fertilizer
One 15-pound bag of the slow-release nitrogen produces yearlong effects in a single treatment over a 10,000-square-foot area
Releases one quarter of its nitrogen in the first three to five weeks, releasing the remaining nitrogen in over a six- to 12-month period
Low-phosphorous fertilizer encourages the 18 species of mycorrhiza to colonize, extending root systems and increasing water and nutrient absorption
Chelated and water-soluble iron is included for improving color
