Covering up to 16,000 sq ft per gallon, it delivers visible lawn greening within 24-48 hours by stimulating nutrient uptake through nitrogen-driven growth. Ideal for professionals and lawn enthusiasts seeking a deep blue-green, glossy finish that stands out in any neighborhood. ## Description Greene EfFect is formulated with citric acid that gives it the ability to absorb directly into leaf tissue instead of having to get watered into the soil and taken in by the roots. Spraying this product on the lawn in a finer mist is recommended, and you will see results within 24-48 hours. All of the intake through foliage happens within an hour so if it does rain, or you happen to water it in everything will be fine. Nitrogen Drives The Bus Another little known fact here is this product contains a small amount of nitrogen. Nitrogen gives lawns a green color for sure, but in this mix, the nitrogen is there to stimulate intake of the iron. You see, nitrogen pushes growth and a grass plant has to be growing (moving, circulating) in order to utilize nutrients like iron to their fullest. Think of the Nitrogen like the Pre-Workout for the iron. That's pretty much what it does and that is another reason the Greene EfFect works so well. More About Greene EfFect The recommended application rate is 8 oz/1,000 sq ft. We recommend you apply this with a pump/battery sprayer and use a tip that uses a finer droplet so this product can coat the leaves of the grass plant. You will actually see a shine or sheen to the lawn after an application - that's what we want! So how long will this last you? The recommended application rate is 8 oz/1,000 sq ft. 1 gallon = 128 oz At the app rate of 8 oz/1,000 sq ft, you will get: 16,000 sq ft of coverage from a single gallon Storage: Store in a cool dry place away from direct sunlight. Product will store for 2 years under warehouse conditions. Review: The best if used! - This stuff works great!

I look like a pro with this product and with some self TLC I have been given my yard. #cancel true green ### ⭐⭐⭐⭐⭐ I can’t believe it *by B***Z on April 22, 2022* I was worried a bit when my grass went from green to yellowish. I thought it was lack of Fe or Iron. I was also suspecting it was fungus so I treated it with Scotts Disease Ex. Still nothing happen. More on yellowish and brown. I watched the Lawn Care Nut channel in YouTube. Bought and applied the product with my backpack sprayer on a mist spray. I can’t believe what I saw. The next day I saw the effect and after 3 days, it look like the picture I posted on this comment. It was the lack of nitrogen that causes it to look like yellow green. This product will stain, so be aware. 7:1 is the ratio mix it with water. ## Frequently Bought Together - Nitrogen Fertilizer + High Iron (6%) 7-0-0 Greene Effect by Greene County Fertilizer Deep Blue Green Color Lawn - MicroGreene 0-0-2 - Micronutrient Supplement with Bio-Stimulants - 4 Gallon Pack (512 oz) Covers up to 85,200 sq ft - Stimulate Roots and Soil Activity, Increase Plant Health, Improve Soil Fertility and Water Holding Capacity - 0-0-1 RGS Root Growth Bio-Stimulant, Sea Kelp | N-Ext --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/343249650-nitrogen-fertilizer-high-iron-6-7-0-0-greene-effect](https://www.desertcart.co.uk/products/343249650-nitrogen-fertilizer-high-iron-6-7-0-0-greene-effect) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-08*
