Not All Fertilizers Are The Same.

Cheap fertilizers make big promises and deliver weak results. Why? Because particle size matters. Oversized nutrient particles can't penetrate plant tissue efficiently, so most of what you apply ends up wasted. GrowIQ+ uses micronized nutrients - ultra-fine particles engineered for maximum absorption through both leaf tissue and root uptake. The result is a highly concentrated formula that covers more ground, feeds faster, and delivers real, visible results - not just a temporary green-up.

Liquid Fertilizer for Stronger Roots, Thicker Turf & Healthier Lawns

Powered by micronized nutrient technology, GrowIQ+ is a high-efficiency 3-18-18 liquid fertilizer designed to deliver phosphorus and potassium directly where your lawn needs it most. No granules to spread, no waiting for rain to dissolve pellets, no guessing if it worked.

 

Micronized Nutrients = Maximum Absorption 

Most liquid fertilizers use oversized nutrient particles that struggle to penetrate plant tissue efficiently. GrowIQ+ uses micronized nutrients - ultra-fine particles engineered for rapid absorption through both leaf tissue and root uptake, so your lawn gets fed faster and more completely with every application.

 

More Coverage. Less Product. 

GrowIQ+'s concentrated formula covers up to 6,000 square feet per quart and a half acre per gallon - significantly more than competing products at the same size. You're not paying for water. You're paying for a professional-grade formula that goes further and delivers real, visible results.

 

Builds a Stronger, More Resilient Lawn 

High phosphorus and potassium work together to drive deep root development, improve drought resistance, and strengthen grass at the cellular level. Whether you're establishing a new lawn or hardening an existing one heading into summer or fall, GrowIQ+ delivers the nutrients your turf needs to thrive.

 

Boosts the Efficiency of Your Entire Fertilizer Program 

Phosphorus is the key to unlocking your soil's full potential. When P and K levels are dialed in, your lawn absorbs nitrogen and other nutrients more efficiently - meaning every product in your program works harder.

 

Easy Application — No Mess, No Guessing 

Apply GrowIQ+ with any sprayer. Hose-end, backpack, boom, or ATV sprayer. No heavy bags, no uneven spreading, and no waiting weeks to see results. One pass and your lawn is fed.

 

Perfect For:

  • Lawns with weak root systems or slow growth
  • New lawn establishment and sod installation
  • Pre-winter hardening and fall fertilizer programs
  • Turf recovering from drought, heat stress, or heavy traffic
  • Homeowners and landscapers who want professional-grade results

Smart Soil. Smarter Growth. GrowIQ+™ delivers the science-backed nutrition your lawn has been waiting for. Whether you're building a dense, green turf from scratch or maintaining what you've got - give your lawn the IQ boost it needs to grow stronger, deeper, and healthier.

GrowIQ+™ Application Instructions

 

Shake well before use. Apply to dry foliage. For best results, apply in the early morning or evening to avoid heat of day.

 

Backpack, Pump & Garden Sprayers

Mix 1.5 oz of GrowIQ+ per gallon of water. Apply evenly across your lawn or garden using a minimum of 2 gallons of mixed solution per 1,000 square feet. A 1-gallon sprayer treats approximately 500 square feet, a 2-gallon sprayer covers around 1,000 square feet, and a 4-gallon backpack sprayer covers up to 2,000 square feet per tank. Spray until foliage is thoroughly wet. Avoid runoff.

 

Hose-End Sprayers

Fill reservoir with GrowIQ+ concentrate and set dial to 2-3 oz per gallon. Spray evenly across lawn using a slow, sweeping motion for uniform coverage. A 1-quart reservoir treats up to 6,000 square feet. A full gallon covers up to ½ acre.

 

Application Schedule

For best results, apply every 2-4 weeks during active growing season. For maintenance on an established lawn, one application per month is sufficient. For new lawns and establishment, apply every 2-4 weeks until desired density is achieved. For nutrient deficient or stressed turf, apply every 14 days until recovery is visible.

 

Tips for Best Results

Apply in the early morning or evening when temperatures are cooler. Avoid application during drought conditions or on dormant grass. Water lawn lightly within 24 hours of application if no rain is expected. GrowIQ+ is compatible with most pesticides and other liquid fertilizers and is safe for all grass types including Bermuda, Fescue, Kentucky Bluegrass, Zoysia, St. Augustine, and Ryegrass.
