N-Ext GreenePunch 18-0-1 Fertilizer

"Punch Up" Your Lawn's Color

N-Ext GreenePunch 18-0-1 Logo
18-0-1 GreenePunch Lawn Fertilizer is a liquid fert that is the foundation of my All-Liquid lawn plans.
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 Milo/CX DIY applications but again, not for beginners.
