This product is 2.5 Gallons of MicroGreene 0-0-2 Plant and Ornamental Fertilizer and 2.5 Gallons of Greene EfFect 7-0-0 Turf and Ornamental Fertilizer plus Iron.

I call this combo the "Double Dark" because it is really all about stimulating a color pop. The term "Double Dark" was originally coined by my friend Jake The Lawn Kid in this video here

On the backside, however, this combo will even out your micronutrient load which is good for everything else the turf is trying to do. I started using this in between my regular fert apps to extend the color pop and it’s worked nicely.

This app should be done from a pump sprayer and keep it even and consistent across the lawn. Any areas you get too heavy on will be darker and if you miss any spots, you’ll be able to tell - so make sure you watch what you are doing here. This also makes a nice addition to your domination line if you want to get it just a little darker on the edges.

The rates I use for my "Double Dark" apps are:

  • 9 oz - MicroGreene
  • 6 oz - Greene Effect

So you'd combine both of these together in your pump sprayer. 

MicroGreene 0-0-2

Now if you’ve ever done a soil test you know that we care about the macronutrients and micronutrients in the soil.

The macronutrients N-P-K (Nitrogen-Phosphorus-Potassium) we can get from fertilizers.

But what about micronutrients?

That’s where the MicroGreene comes in.

MicroGreene gives us Magnesium, Sulfur, Iron, Manganese, and Zinc and is the perfect micro stack to hit all of your bases.

Plus when you throw’er down it gives you a visual response in the lawn within just a few days.

Typically the lawn turns quite dark blue-green from the heavier applications of 9 oz/gallon/1,000 sq ft.

The recommended application rate for MicroGreene is 9 oz per 1,000 sq ft.

With this product, you’ll receive one 2.5-gallon jug of MicroGreene 0-0-2.

  • 2.5 gallons = 320 oz

At the app rate of 9 oz/1,000 sq ft, you will get:

  • 35,500 sq ft of coverage from a 2.5-gallon jug

For a 5,000 sq ft lawn, this means you will get ~7 total applications: 

  • 9 oz/1,000 sq ft x 5 = 45 oz
  • 320 oz/45 oz = 7.1 total applications


7-0-0 GreeNe EfFect Turf & Ornamental Fertilizer Plus 6% Iron

Analysis: 7-0-0

This means 7% of the liquid is nitrogen (remember, the 3 numbers are your macros, N-P-K). But there is also a note that this product contains 6% Iron.

What this is literally telling you is:

  • 7% of everything in this bottle in nitrogen
  • 6% of everything in this bottle is iron

The recommended application rate on the jug is 8 oz/1,000 sq ft.

(My app rate for the Double Dark is slightly less at 6 oz/1,000 sq ft)

Here’s the end result of breaking down the math into lbs/1,000 sq ft:

You’ll get 0.04 lbs N with an 8 oz/gallon application rate. Not much to write home about right? You guys are used to putting down some real “pounds on the ground” and at least getting .5 or .75 lbs/N per 1,000… but that’s with our granular apps.

That’s where the other piece kicks in and that’s the Fe - our old buddy IRON!

Iron is what gives lawns a deeper “blue” look that really sets them off. Our best friend Milo contains iron and that’s one reason we love him… but sometimes, you need just a little boost in between and that’s where this product really does shine.

You’ll get .038 lbs Fe with an 8 oz/gallon application rate (remember, 1 gallon covers 1,000 square feet). Which also seems unimpressive until you remember the following facts.

Nitrogen is a “Macronutrient” meaning there is a lot more of it needed for optimum plant health. In fact, it’s the mack-daddy of the macros! We lawn care nuts are addicted to it!

But there are some drawbacks to too much N - namely - over-pushing of growth. I think we do just fine with our N rates, pushing them to the max using Milo of course.

Iron, on the other hand, is a “Micronutrient” meaning you only need small, spoon-fed amounts in order to push plants to optimum levels. It takes much less “pounds on the ground” of iron to get a visual response.

The recommended amount of iron in the soil is 2-4 ppm. Nitrogen on the other hand, is 8-16 ppm.

And that is where the secret weapon of the 7-0-0 GreeneEffect is revealed.

The iron is like a little liquid green bomb that you can apply in between your regular fert apps to keep everything looking double dark WITHOUT pushing a flush of growth. The N that is in the product is certainly going to help, but it’s really the iron we want.

My recommended application rate of 7-0-0 Greene Effect for the "Double Dark" is 6 oz per 1,000 sq ft.

With this product, you’ll receive one 2.5-gallon jug of 7-0-0 Greene Effect

  • 2.5 gallons = 320 oz

At the app rate of 6 oz/1,000 sq ft, you will get:

  • 53,300 sq ft of coverage from a 2.5-gallon jug

For a 5,000 sq ft lawn, this means you will get ~11 total applications: 

  • 6 oz/1,000 sq ft x 5 = 30 oz
  • 320 oz/30 oz = 10.6 total applications

Keep this in mind when you decide how much you need. If your yard is not that big, consider splitting with a neighbor or family member.
