Pros
  • Chelated iron plus a 6-12-3.3 NPK blend in one liquid product
  • Fast-acting formula for correcting yellowing

  • Suits lawns, trees, shrubs and bushes
  • Sugar-based chelating agents instead of harsher synthetics
Cons
  • High phosphorus relative to nitrogen suits deficiency correction more than general feeding

  • 2.5-gallon jug is heavy and awkward to carry for small jobs
  • Liquid concentrate needs mixing and measuring
  • Iron stains and over-application can damage surfaces and plants

Questions and answers

What does the 6-12-3.3 ratio mean?
It is 6% nitrogen, 12% phosphate and 3.3% potash by weight, with chelated iron added. The high phosphorus share makes it a corrective feed rather than a balanced all-purpose fertilizer.
How do I apply it to a lawn?
It can go on as a root drench or a foliar spray. Mix according to the label rate, water it in for root application, and spray foliage in cooler hours to limit burn.
Will it fix yellow grass?
It is made for yellowing caused by iron deficiency, and chelated iron is the fast-acting part. If the yellowing comes from drought, disease or nitrogen shortage, this blend may not be the fix.
Is it organic?
Covington Naturals says many of its products are all natural and uses sugar-based chelating agents. Check the label for the specific organic certification on this jug.
What sizes are available?
Listings show quart and 2.5-gallon sizes, with the gallon jug also referenced. The 2.5-gallon jug is the size priced at $69.95 at Covington Naturals as of November 7, 2026.
When is the best time to apply it?
Apply in spring or early fall when plants are actively growing, and avoid the heat of the day for foliar sprays. Do not apply before heavy rain if you want the iron to stay on the foliage.
