Grow More® Grow-vite 16-4-2 — 1 gal Concentrate

High-Nitrogen Liquid Concentrate With Chelated Micronutrients and a Built-In Soil Penetrant

A high-nitrogen liquid fertilizer that never reaches the root zone is wasted product, and a micronutrient package that locks out at neutral soil pH does little for leaf color. Grow More Grow-vite 16-4-2 pairs a nitrogen-forward NPK ratio with chelated iron, zinc, and manganese that stay plant-available across a wide pH range, then adds a soil penetrant that moves the whole formula past compacted or hydrophobic soil into actual root contact.

The 1 gallon concentrate dilutes into many applications, giving lawns, ornamental beds, and vegetable gardens a single liquid fertilizer that covers macronutrient feeding and micronutrient correction in one pass.

Key Features & Benefits

• 16-4-2 NPK Ratio: High-nitrogen, low-phosphorus, low-potassium formula built for vegetative growth and sustained green color in lawns, foliage, and fast-growing vegetables.
• Chelated Iron, Zinc, and Manganese: Stay plant-available across a wide range of soil pH, preventing the interveinal chlorosis that occurs when unchelated forms lock out in neutral to alkaline soils.
• Built-In Soil Penetrant: Improves water and nutrient movement through the soil profile so the formula reaches actively growing roots instead of pooling at the surface.
• Liquid Concentrate Economy: A single gallon produces many diluted applications, keeping cost per feeding low across an ongoing fertilizer program.
• Versatile Application: Suited to lawns, ornamental flowers, and vegetable gardens as one all-purpose liquid.

Who Should Use This

Home gardeners, lawn care enthusiasts, and landscape contractors who want one reliable liquid fertilizer with chelated micronutrients for lawns, beds, and vegetable gardens are the direct fit, especially in soils where iron chlorosis or zinc deficiency limit color and growth.

About Grow More Inc.

Grow More Inc. has manufactured fertilizers since 1918, starting as National Chemical Company in Hollywood, California and now based in Gardena, California, with Grow-vite serving as its chelated-micronutrient liquid concentrate for lawn and garden use.

Frequently Asked Questions

What is the purpose of the soil penetrant in Grow-vite?

The penetrant is a surfactant that reduces water surface tension and improves movement through the soil profile. That means the chelated micronutrients and macronutrients penetrate toward the root zone rather than running off the surface or pooling in the shallow soil layer.

Why are chelated iron, zinc, and manganese included in a general-purpose fertilizer?

These three micronutrients are the most commonly deficient in lawn, ornamental, and vegetable growing because they become insoluble above roughly pH 6.5 to 7.0, the range of most landscape soils. Chelating them ensures every application delivers both the primary NPK and the micronutrients most likely to be limiting.

Can I use Grow-vite on newly seeded lawns?

It can be applied to newly seeded or sodded lawns once grass is established and has been mowed at least once, starting at a reduced concentration and increasing to full strength as the lawn matures. Avoid applying to bare soil before germination, since high nitrogen concentrations can inhibit germination in some grass species.

How does the 16-4-2 ratio compare to a balanced 20-20-20 formula?

16-4-2 is strongly nitrogen-dominant, ideal for vegetative growth, dense foliage, and deep green color in lawns and leafy crops. A balanced 20-20-20 suits situations needing equal nitrogen, phosphorus, and potassium across all growth stages, including flowering and fruiting.
