N-Ext GreenePunch™ 18-0-1 Complete Liquid Fertilizer for Lawns

N-Ext GreenePunch™ 18-0-1 Complete Liquid Fertilizer for Lawns

N-Ext 18-0-1 GreenePunch™ is a complete liquid lawn fertilizer designed for homeowners who prefer liquid applications over granular products. It combines liquid nitrogen, potassium, iron, macronutrients, micronutrients, humic acid, and sea kelp extract in one complete formula to support the grass plant and the soil beneath it.

Nitrogen supports healthy turf growth, while iron helps promote a rich green lawn color. Potassium supports overall plant health, and humic acid and sea kelp help promote healthy soil biology, nutrient availability, and root development. Together, these ingredients help deliver fast green-up, steady color, and strong root growth without encouraging excessive surge growth.

GreenePunch is the foundation of many all-liquid lawn care programs and can help maintain consistent turf color and performance for approximately 4–6 weeks after application. It is easy to apply with a backpack sprayer, a pump sprayer, or a compatible hose-end sprayer, and it can be used on all grass types throughout the growing season.
