7-7-7 Seven Iron has all of the same great qualities as all GreenSpec products PLUS these unique qualities:
Formulated to produce dark green color and correct nutrient depleted soils.
Contains micronutrients specially formulated with sugars called "sucrates".
As a result, these micros are absorbed much more quickly than those in traditional lawn fertilizers.
Especially effective to promote recovery from mechanical or environmental stress and during turfgrass establishment.
A multi-purpose plant food, starter fertilizer, pre-plant, and soil conditioning fertilizer that has been specially designed for use in all seasons. 7-7-7 Seven Iron™ contains 7% iron in both quickly and slowly available forms. Iron sulfate provides a more immediate response, while iron sucrate helps maintain long-term color.
Nutrient release and subsequent plant uptake determined by microbial activity and will vary based on soil moisture, temperature, pH, and turfgrass species.
