18-0-1 GreenePunch Lawn Fertilizer is a liquid fert that is the foundation of my All-Liquid lawn plan.

This is not a product for beginners. It can be a replacement for regular fertilizer applications for those of you who prefer a liquid application method. It can also be used to really "Punch Up" your lawn's color in between regular fertilizer applications but again, not for beginners.

It is recommended to be watered in immediately after application.

  • 18-0-1 GreenePunch™ Lawn Fertilizer is engineered to be a complete product for all varieties of turfgrass. It is formulated to produce a quick green-up response and maintain consistent color for 6-8 weeks. It makes a great fertilizer for those who prefer a liquid option.

  • 18-0-1 GreenePunch™ will produce a strong root mass which will grow deeply into the soil. It will stimulate soil activity necessary for building sustainable fertility. 

  • For specific 18-0-1 GreenePunch™ application instructions related to Turf Type, Season, Spray Equipment, applying with N-Ext™ specialty products, pesticides, watering-in, etc. please visit greenecountyfert.com/diy/.

The recommended application rate is 16 oz/1,000 sq ft.

We have two offerings - 4 gallons (4, 1 gallon jugs) and 5 gallons (2, 2.5 gallon jugs):

  • 1 gallon = 128 oz
  • 2.5 gallons = 320 oz
  • 4 gallons = 512 oz
  • 5 gallons = 640 oz

At the app rate of 16 oz/1,000 sq ft, you will get:

  • 8,000 sq ft of coverage from a single gallon
  • 20,000 sq ft of coverage from a 2.5-gallon jug
  • 32,000 sq ft of coverage from 4 gallons
  • 40,000 sq ft of coverage from the full 5 gallons 

For a 5,000 sq ft lawn, this means you will get ~6 total applications from 4 gallons:  

16 oz/1,000 sq ft x 5 = 80 oz

512 oz/80 oz = 6.4 total applications 

For a 5,000 sq ft lawn, this means you will get 8 total applications from 5 gallons:  

16 oz/1,000 sq ft x 5 = 80 oz

640 oz/80 oz = 8 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.

If you are not fully understanding of this part of the math, you should probably wait on this product until we get some further content out about it.

Don't rush ahead too fast - this is an advanced strategy and you will get there soon!
