Dyna-Gro Foliage-Pro 9-3-6 Complete Liquid Nutrient for Foliage Plants – 1 Quart

Dyna-Gro Foliage-Pro 9-3-6 is a complete liquid plant nutrient formulated for the vegetative growth phase and for foliage-focused plant applications. The 9-3-6 ratio follows the 3-1-2 N-P-K proportion recommended by the Apopka Research Center in Florida — a ratio found to produce healthy, controlled vegetative growth in tropical foliage and interior scape plants without triggering excessive growth or deficiency symptoms.

Foliage-Pro 9-3-6 is urea-free. Urea is a nitrogen form that must be converted by soil microorganisms before plants can use it — in soilless systems like hydroponics or interior scape containers where microbial activity is lower, urea nitrogen can remain unavailable or convert to ammonia and create salt buildup over time. Foliage-Pro uses nitrogen forms that are directly available to plants in all growing media, making it suitable for continuous feeding programs in soil, coco, hydroponic systems, and interior scape installations.

Key Features & Benefits

• 9-3-6 High Nitrogen Ratio — 3-1-2 N-P-K proportion for steady, controlled vegetative growth.
• Urea-Free Formula — Directly available nitrogen — compatible with soil, soilless, and hydroponic growing media.
• All 16 Essential Nutrients — Complete macro and micronutrient profile in one product.
• Continuous Use Program — Designed for ongoing feeding without rotation or supplementation.
• Tropical Foliage and Interior Scape — Developed for the specific nutrient demands of foliage and interior plant production.
• Reduces Salt Buildup — Urea-free nitrogen avoids the salt accumulation associated with urea-based nutrients.
• One-Quart Size — For smaller operations or trial use.

Who Should Use Foliage-Pro 9-3-6

Foliage-Pro 9-3-6 is for growers and interior scape operators focused on vegetative health and foliage quality. It is appropriate for tropical plants, foliage houseplants, interior installations, and any production where the goal is sustained healthy green growth rather than flowering or fruiting.

Why the 3-1-2 N-P-K Ratio for Foliage

The 3-1-2 N-P-K ratio (represented in Foliage-Pro 9-3-6 as 9 parts N, 3 parts P, 6 parts K) was developed through field and laboratory research as the optimal proportion for sustained foliage production. High nitrogen supports protein synthesis and chlorophyll production, giving plants deep green color and vigorous leaf growth. Low phosphorus prevents the premature triggering of reproductive development — high phosphorus signals the plant to shift energy toward flowering, which is counterproductive in foliage applications. The balanced potassium supports overall plant function, root development, and environmental stress tolerance.

Frequently Asked Questions

What is the N-P-K ratio?

9-3-6, following the 3-1-2 N-P-K proportion.

Why is it urea-free?

Urea must be converted by soil microorganisms before plants can use it. In soilless or hydroponic systems with lower microbial activity, urea nitrogen may be unavailable or cause salt buildup. Foliage-Pro uses directly plant-available nitrogen forms.

Is it compatible with hydroponic systems?

Yes. The urea-free formula is appropriate for soil, soilless, and hydroponic growing systems.

Can it be used continuously?

Yes. Foliage-Pro is designed as a continuous-use nutrient program.
