What’s inside?

Greenify isn’t just nitrogen. It’s a smarter formula that fuels color and strength at the same time:

  • 12% Nitrogen (Urea): Quick-release for fast visible results
  • 6% Chelated Iron: For rich, dark green color
  • 5% Sulfur: Supports chlorophyll production and soil pH balance
  • 3% Magnesium: Boosts photosynthesis and overall turf health

    Why chelated iron? It absorbs quickly and doesn’t wash away, so your lawn gets more of what it needs, faster.
