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

All-Purpose Liquid Fertilizer with Chelated Micronutrients and Soil Penetrant for Lawns, Flowers, and Vegetables

Grow More® Grow-vite 16-4-2 is a concentrated liquid all-purpose fertilizer formulated with chelated iron, zinc, and manganese alongside a special soil penetrant that ensures these essential micronutrients reach the root zone effectively. The high-nitrogen 16-4-2 NPK profile drives vigorous vegetative growth and deep, lasting green color in lawns and foliage crops, while the chelated micronutrient package prevents the deficiency symptoms that commonly limit plant performance in a wide range of growing conditions.

Key Features & Benefits

• 16-4-2 NPK Ratio: High-nitrogen, low-phosphorus, low-potassium formula optimized for vegetative growth and sustained green color in lawns, ornamental foliage, and fast-growing vegetable crops.
• Chelated Iron, Zinc, and Manganese: Chelated micronutrients remain plant-available across a wide range of soil pH conditions, preventing the interveinal chlorosis and growth disorders that occur when unchelated iron, zinc, and manganese become unavailable in neutral to alkaline soils.
• Special Soil Penetrant: The integrated soil penetrant improves the movement of nutrients through the soil profile and into the root zone, ensuring the chelated micronutrients and macronutrients in the formula reach actively growing roots rather than remaining in the surface application zone.
• Liquid Concentrate: Concentrated liquid format provides excellent economy of use — a single gallon produces multiple diluted applications, making it a cost-effective choice for ongoing fertilizer programs.
• Versatile Application: Ideal for lawns, ornamental flowers, and food gardens including vegetables — a true all-purpose liquid that covers the full range of home and professional growing needs.

Who Should Use This

Grow-vite 16-4-2 is ideal for home gardeners, lawn care enthusiasts, and professional landscape contractors who want a single, reliable liquid fertilizer with chelated micronutrients that delivers consistent results on lawns, ornamental beds, and vegetable gardens. It is particularly valuable in soils where iron chlorosis and zinc deficiency are common problems that limit plant color and growth.

Compatibility

Dilute per label instructions and apply as a soil drench, through hose-end sprayers, or via drip irrigation. Can also be used as a diluted foliar spray during the vegetative growth phase. Compatible with standard lawn and garden fertilizer programs. The integrated soil penetrant provides additional benefit in compacted soils or growing media with hydrophobic tendencies.

Frequently Asked Questions

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

The soil penetrant is a surfactant that reduces water surface tension and improves water and nutrient movement through the soil profile. In lawns and garden beds, this means the chelated micronutrients and macronutrients in Grow-vite penetrate deeper into the root zone rather than running off the surface or concentrating in the shallow soil layer, improving nutrient delivery efficiency and root-zone contact.

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 situations because they become insoluble and unavailable at pH levels above 6.5–7.0 — the pH range of most landscape soils. Including them in chelated form in a general-purpose fertilizer ensures that every application delivers both the primary NPK nutrients and the micronutrients most likely to be limiting plant performance.

Can I use Grow-vite on newly seeded lawns?

Grow-vite can be applied to newly seeded or sodded lawns once grass is established and has been mowed at least once. Apply at a reduced concentration initially and increase to full strength as the lawn matures. Avoid applying to bare soil before germination as high nitrogen concentrations can inhibit germination in some grass species.

Is Grow-vite suitable for use on edible vegetable crops?

Yes. Grow-vite 16-4-2 is listed as suitable for vegetables. Apply as a soil drench around the root zone and allow a suitable pre-harvest interval per the product label before harvesting edible portions. The chelated micronutrients are particularly beneficial for fruiting vegetables that require iron and manganese for chlorophyll production and metabolic function.

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

16-4-2 is strongly nitrogen-dominant — ideal for promoting vegetative growth, dense foliage, and deep green color in lawns and leafy crops. A balanced 20-20-20 is better suited to situations where equal nitrogen, phosphorus, and potassium are needed throughout all growth stages. Use Grow-vite when the primary goal is vigorous vegetative response and color; use a balanced formula when supporting flowering and fruiting alongside vegetative growth.
