This is 2-gallons in two 1 gallon bottles

1 Gallon of N-Ext 7-0-0 Greene Effect
1 Gallon of N-Ext 0-0-2 MicroGreene

 This is the famous iron combo that you've heard about, now available in a convenient 2-gallon pack. This is the fastest and most economical way to turn your lawn double dark blue-green and keep it that way for 4-6 weeks. With this combo, you get green through the shoots and more green through the roots - double dark! Look for results in a few days and watch it get darker and darker over the following weeks.

N-Ext 7-0-0 Greene EfFect™ combines nitrogen and iron uniquely to give you a greener lawn, without a growth push. 7-0-0 Greene EfFect™ can be absorbed directly into grass leaf tissue, which brings a faster green-up.

N-Ext 0-0-2 MicroGreene™ is a micronutrient fertilizer with humic and sea kelp. If you have a soil test showing micronutrient deficiencies then this is your go-to product to get your levels moving in the right direction.

Application Information: 

We recommend you apply this via a pump sprayer or battery sprayer and use a tip that delivers a smaller (finer) droplet size.
Fill the sprayer halfway with water first (important).
7-0-0 Greene Effect rate: 6oz/gallon
0-0-2 MicroGreene Rate: 6 oz/gallon
1 gallon of spray mix covers 1,000 sq ft.
Agitate and fill the sprayer up the rest of the way.

Spray this mix onto the grass and let it sit. You want to coat or "paint" the blades of grass. You will notice a silvery sheen on the grass blades after the application.
Let it sit for a good 45 - 60 minutes and then go ahead and water it in with 1/4" of water.

Can be applied at any time during the growing season for cool and warm-season lawns. 

These products can be used on all grass types, including the following:
Cool Season Lawns - Kentucky Bluegrass, Turf Type Tall Fescue (all fescues), Ryegrass.
Warm Season Lawns - Bermuda, St Augustine, Zoysia, Centipede, Bahia. (This is an excellent year-round application for centipede grass. Use this combo for all of your applications, all season long and you will have some happy centipede.)

Dark Green Lawn

Worked great on my Zoysia which needed a little "help" before a wedding we were having at the house. Turned the lawn a nice deep green...
