Trust Badge

In the Seeding and Over-Seeding Pack, you’ll get 4-Gallons in four 1 gallon bottles

  • 1 Gallon of N-Ext 0-0-1 RGS
  • 1 Gallon of N-Ext 9-0-1 GreeneStart
  • 1 Gallon of N-Ext 16-21-2 GreenePOP
  • 1 Gallon 18-0-1 GreenePunch

This pack is everything you need for seeding and/or over-seeding with four products that provide the seeds with everything they need to thrive.  

[N-Ext] RGS Stands for Root Growth Stimulant and that’s exactly what it does. This biostimulant is packed with hormones from sea kelp that stimulate roots and stolons/rhizomes coupled with chelating humic acid.

N-Ext 9-0-1 Greene Start™ Multipurpose Fertilizer is a complete product for seeding and drought-stressed lawn situations. It also makes for a great low nitrogen spoon-feeding.

N-Ext 16-21-2 GreenePOP™ is a liquid starter fertilizer. If you are seeding or sodding your lawn, this is your foundation product. It's also great for existing lawns if you need a good dose of phosphorus to correct a deficiency. Also includes liquid aeration in the mix.

N-Ext 18-0-1 GreenePunch™ is a liquid fertilizer that is the foundation of our All-Liquid lawn plans. If you prefer to apply liquid lawn ferts vs. granular, the GreenePunch is an excellent choice.
